<div><h4>Acute Coronary Occlusion in Patients With Non-ST-Segment Elevation Out-of-Hospital Cardiac Arrest.</h4><i>Spirito A, Vaisnora L, Papadis A, Iacovelli F, ... Windecker S, Räber L</i><br /><b>Background</b><br />According to current guidelines, hemodynamic status should guide the decision between immediate and delayed coronary angiography (CAG) in out-of-hospital cardiac arrest (OHCA) patients without ST-segment elevation. A delayed strategy is advised in hemodynamically stable patients, and an immediate approach is recommended in unstable patients.<br /><b>Objectives</b><br />This study sought to assess the frequency, predictors, and clinical impact of acute coronary occlusion in hemodynamically stable and unstable OHCA patients without ST-segment elevation.<br /><b>Methods</b><br />Consecutive unconscious OHCA patients without ST-segment elevation who were undergoing CAG at Bern University Hospital (Bern, Switzerland) between 2011 and 2019 were included. Frequency and predictors of acute coronary artery occlusions and their impact on all-cause and cardiovascular mortality at 1 year were assessed.<br /><b>Results</b><br />Among the 386 patients, 169 (43.8%) were hemodynamically stable. Acute coronary occlusions were found in 19.5% of stable and 24.0% of unstable OHCA patients (P = 0.407), and the presence of these occlusions was predicted by initial chest pain and shockable rhythm, but not by hemodynamic status. Acute coronary occlusion was associated with an increased risk of cardiovascular death (adjusted HR: 2.74; 95% CI: 1.22-6.15) but not of all-cause death (adjusted HR: 0.72; 95% CI: 0.44-1.18). Hemodynamic instability was not predictive of fatal outcomes.<br /><b>Conclusions</b><br />Acute coronary artery occlusions were found in 1 in 5 OHCA patients without ST-segment elevation. The frequency of these occlusions did not differ between stable and unstable patients, and the occlusions were associated with a higher risk of cardiovascular death. In OHCA patients without ST-segment elevation, chest pain or shockable rhythm rather than hemodynamic status identifies patients with acute coronary occlusion.<br /><br />Copyright © 2023 American College of Cardiology Foundation.

<div><h4>Outcomes with catheter-directed thrombolysis versus catheter-directed embolectomy among patients with high-risk pulmonary embolism: A nationwide analysis.</h4><i>Sedhom R, Elbadawi A, Megaly M, Athar A, ... Jaber W, Elgendy IY</i><br /><b>Objective</b><br />To examine the clinical outcomes with catheter-directed thrombolysis (CDT) vs. catheter-directed embolectomy (CDE) for high-risk pulmonary embolism (PE).<br /><b>Background</b><br />Comparative data on the short-term outcomes for CDE vs. CDT among patients with high-risk PE are scarce.<br /><b>Methods</b><br />The Nationwide Readmissions Database was utilized to identify hospitalizations with high-risk PE undergoing CDE or CDT from 2016 to 2019. The main outcome of interest was all-cause in-hospital mortality. Propensity score matching was used to compare the outcomes in both groups.<br /><b>Results</b><br />Among 3,216 high-risk PE hospitalizations undergoing catheter-directed interventions, 868 (27%) received CDE, 1,864 (58%) received CDT and 484 (15%) received both procedures. In the unadjusted analysis, the rate of all-cause in-hospital mortality was not between both CDE and CDT (39.6% vs. 34.2%, P = 0.07). After propensity score matching, CDE was not associated with higher mortality (adjusted odds ratio [OR] 1.28, 95% confidence interval [CI] 0.95, 1.72, P = 0.10), intracranial hemorrhage (ICH) (adjusted OR 1.57, 95% CI 0.75, 3.29, P = 0.23) or non-ICH bleeding (adjusted OR 1.17, 95% CI 0.85, 1.62, P = 0.33). There were no differences in the length of stay, cost and 30-day unplanned readmissions between both groups.<br /><b>Conclusions</b><br />In this contemporary observational analysis of patients admitted with high-risk PE undergoing CDT or CDE, the rates of in-hospital mortality, ICH and non-ICH bleeding events were not different.<br /><br />© The Author(s) 2023.

<div><h4>Quality indicators for post-resuscitation care after out-of-hospital cardiac arrest: A Joint statement from the Association for Acute CardioVascular Care (ACVC) of the European Society of Cardiology, the European Resuscitation Council (ERC), the European Society of Intensive Care Medicine (ESICM), and the European Society for Emergency Medicine (EUSEM).</h4><i>Grand J, Schiele F, Hassager C, Nolan JP, ... Price S, Jorge-Perez P</i><br /><AbstractText>Quality of care (QoC) is a fundamental tenet of modern healthcare and has become an important assessment-tool for healthcare authorities, stakeholders and the public. However, QoC is difficult to measure and quantify because it is a multifactorial and multidimensional concept. Comparison of clinical institutions can be challenging when QoC is estimated solely based on clinical outcomes. Thus, measuring quality through quality indicators (QIs) can provide a foundation for quality assessment and has become widely used in this context. QIs for the evaluation of QoC in acute myocardial infarction are now well-established, but no such indicators exist for the process from resuscitation of cardiac arrest and post-resuscitation care in Europe. In this context, the Association of Acute Cardiovascular Care of the European Society Cardiology, the European Resuscitation Council, European Society of Intensive Care Medicine and the European Society for Emergency Medicine, have reflected on the measurement of QoC in cardiac arrest. A set of QIs have been proposed, with the scope to unify and evolve QoC for the management of cardiac arrest across Europe. We present here the list of QIs (6 primary QIs and 12 secondary Qis), with descriptions of the methodology used, scientific justification and motives for the choice for each measure with the aim that this set of QIs will enable assessment of the quality of post-out-of-hospital cardiac arrest management across Europe.</AbstractText><br /><br />© The Author(s) 2023.

<div><h4>Single antiplatelet therapy directly after percutaneous coronary intervention in non-ST-segment elevation acute coronary syndrome patients: the OPTICA study.</h4><i>van der Sangen NMR, Claessen BEPM, Küçük IT, den Hartog AW, ... Appelman Y, Henriques JPS</i><br /><b>Background</b><br />Early P2Y<sub>12</sub> inhibitor monotherapy has emerged as a promising alternative to 12 months of dual antiplatelet therapy following percutaneous coronary intervention (PCI).<br /><b>Aims</b><br />In this single-arm pilot study, we evaluated the feasibility and safety of ticagrelor or prasugrel monotherapy directly following PCI in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS).<br /><b>Methods</b><br />Patients received a loading dose of ticagrelor or prasugrel before undergoing platelet function testing and subsequent PCI using new-generation drug-eluting stents. The stent result was adjudicated with optical coherence tomography in the first 35 patients. Ticagrelor or prasugrel monotherapy was continued for 12 months. The primary ischaemic endpoint was the composite of all-cause mortality, myocardial infarction, definite or probable stent thrombosis or stroke within 6 months. The primary bleeding endpoint was Bleeding Academic Research Consortium type 2, 3 or 5 bleeding within 6 months.<br /><b>Results</b><br />From March 2021 to March 2022, 125 patients were enrolled, of whom 75 ultimately met all in- and exclusion criteria (mean age 64.5 years, 29.3% women). Overall, 70 out of 75 (93.3%) patients were treated with ticagrelor or prasugrel monotherapy directly following PCI. The primary ischaemic endpoint occurred in 3 (4.0%) patients within 6 months. No cases of stent thrombosis or spontaneous myocardial infarction occurred. The primary bleeding endpoint occurred in 7 (9.3%) patients within 6 months.<br /><b>Conclusions</b><br />This study provides first-in-human evidence that P2Y<sub>12</sub> inhibitor monotherapy directly following PCI for NSTE-ACS is feasible, without any overt safety concerns, and highlights the need for randomised controlled trials comparing direct P2Y<sub>12</sub> inhibitor monotherapy with the current standard of care.<br /><br /><br /><br /><small>EuroIntervention: 03 Feb 2023; epub ahead of print</small></div>

Abstract
<div><h4>Patterns and Outcomes of Intensive Care on Acute Ischemic Stroke Patients in the US.</h4><i>Santos D, Maillie L, Dhamoon MS</i><br /><b>Background</b><br />Up to 20% of acute ischemic stroke (AIS) patients may benefit from intensive care unit (ICU)-level care; however, there are few studies evaluating ICU availability for AIS. We aim to summarize the proportion of elderly AIS patients in the United States who are admitted to an ICU and assess the national availability of ICU-level care in AIS.<br /><b>Methods</b><br />We performed a retrospective cohort study using de-identified Medicare inpatient datasets from January 1, 2016 through December 31, 2019 for US individuals aged ≥65 years. We used validated <i>International Classification of Diseases, Tenth Revision</i>, Clinical Modification codes to identify AIS admission and interventions. ICU-level care was identified by revenue center code. AIS patient characteristics and interventions were stratified by receipt of ICU-level care, comparing differences through calculated standardized mean difference score due to large sample sizes.<br /><b>Results</b><br />From 2016 through 2019, a total of 952 400 admissions by 850 055 individuals met criteria for hospital admission for AIS with 19.9% involving ICU-level care. Individuals were predominantly >75 years of age (58.5%) and identified as white (80.0%). Hospitals on average admitted 11.4% (SD 14.6) of AIS patients to the ICU, with the median hospital admitting 7.7% of AIS patients to the ICU. The ICU admissions were younger and more likely to receive reperfusion therapy but had more comorbid conditions and neurologic complications. Of the 5084 hospitals included, 1971 (38.8%) reported no ICU-level AIS care. Teaching hospitals (36.9% versus 1.6%, <i>P</i><0.0001) with larger AIS volume (<i>P</i><0.0001) or in larger metropolitan areas (<i>P</i><0.0001) were more likely to have an ICU available.<br /><b>Conclusions</b><br />We found evidence of national variation in the availability of ICU-level care for AIS admissions. Since ICUs may provide comprehensive care for the most severe AIS patients, continued effort is needed to examine ICU accessibility and utility among AIS.<br /><br /><br /><br /><small>Circ Cardiovasc Qual Outcomes: 03 Feb 2023:e008961; epub ahead of print</small></div>

<div><h4>Real-world clinical outcomes with a next-generation left atrial appendage closure device: the FLXibility Post-Approval Study.</h4><i>Betts TR, Grygier M, Kudsk JEN, Schmitz T, ... Allocco DJ, FLXibility investigators</i><br /><b>Aims</b><br />The FLXibility Post-Approval Study collected data on unselected patients implanted with a WATCHMAN FLX in a commercial clinical setting.<br /><b>Methods and results</b><br />Patients were implanted with a WATCHMAN FLX per local standard of care, with a subsequent first follow-up visit from 45 to 120 days post-implant and a final follow-up at 1-year post-procedure. A Clinical Event Committee adjudicated all major adverse events and TEE/CT imaging results were adjudicated by a core laboratory. Among 300 patients enrolled at 17 centres in Europe, the mean age was 74.6 ± 8.0 years, mean CHA2DS2-VASc score was 4.3 ± 1.6, and 62.1% were male. The device was successfully implanted in 99.0% (297/300) of patients. The post-implant medication regimen was DAPT for 87.3% (262/300). At first follow-up, core-lab adjudicated complete seal was 88.2% (149/169), 9.5% (16/169) had leak <3 mm, 2.4 (4/169) had leak ≥3 mm to ≤5 mm, and 0% had >5 mm leak. At 1 year, 93.3% (280/300) had final follow-up; 60.5% of patients were on a single antiplatelet medication, 21.4% were on DAPT, 5.6% were on direct oral anticoagulation, and 12.1% were not taking any antiplatelet/anticoagulation medication. Adverse event rates through 1 year were: all-cause death 10.8% (32/295); CV/unexplained death 5.1% (15/295); disabling and non-disabling stroke each 1.0% (3/295, all non-fatal); pericardial effusion requiring surgery or pericardiocentesis 1.0% (3/295); and device-related thrombus 2.4% (7/295).<br /><b>Conclusion</b><br />The WATCHMAN FLX device had excellent procedural success rates, high LAA seal rates, and low rates of thromboembolic events in everyday clinical practice.<br /><br />© The Author(s) 2023.

<div><h4>Clinical Outcome of Revascularization Deferral With Instantaneous Wave-Free Ratio and Fractional Flow Reserve: A 5-Year Follow-Up Substudy From the iFR-SWEDEHEART Trial.</h4><i>Berntorp K, Rylance R, Yndigegn T, Koul S, ... Erlinge D, Götberg M</i><br /><AbstractText><br /><b>Background:</b><br/>Although physiology-based assessment of coronary artery stenosis using instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) are established methods of guiding coronary revascularization, its clinical outcome in long-term deferral needs further evaluation, especially with acute coronary syndrome as a clinical presentation. The aim was to evaluate the long-term clinical outcome of deferral of revascularization based on iFR or FFR. Methods and Results This is a substudy of the iFR-SWEDEHEART (Instantaneous Wave-Free Ratio Versus Fractional Flow Reserve in Patients With Stable Angina Pectoris or Acute Coronary Syndrome) randomized clinical trial, where patients deferred from revascularization from each study arm were selected. Nine hundred eight patients deferred from coronary revascularization with iFR (n=473) and FFR (n=435) were followed for 5 years. The national quality registry, SWEDEHEART (Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies), was used for patient data collection and clinical follow-up. The end point was major adverse cardiac events and their individual components all-cause death, cardiovascular death, noncardiovascular death, nonfatal myocardial infarction, and unplanned revascularization. No significant difference was found in major adverse cardiac events (iFR 18.6% versus FFR 16.8%; adjusted hazard ratio, 1.08 [95% CI, 0.79-1.48]; <i>P</i>=0.63) or their individual components. <br /><b>Conclusions:</b><br/>No differences in clinical outcomes after 5-year follow-up were noted when comparing iFR versus FFR as methods for deferral of coronary revascularization in patients presenting with stable angina pectoris and acute coronary syndrome.

<div><h4>Impact of Impella RP Versus Vasoactive Treatment on Right and Left Ventricular Strain in a Porcine Model of Acute Cardiogenic Shock Induced by Right Coronary Artery Embolization.</h4><i>Frederiksen PH, Josiassen J, Udesen NLJ, Linde L, ... Ravn HB, Møller JE</i><br /><AbstractText><br /><b>Background:</b><br/>The response of the left ventricle to cardiogenic shock (CS) caused by right ventricular (RV) infarction and the effect of treatment with either vasoactive treatment or Impella RP are not well described. We sought to determine RV and left ventricular longitudinal strain (LS) by echocardiography after initiation of either Impella RP or vasoactive treatment for CS induced by right coronary artery embolization. Methods and Results CS was induced with microsphere embolization in the right coronary artery in 20 pigs. Shock was defined as a reduction in cardiac output of ≥50% and/or an SvO<sub>2</sub> <30%. At the time of CS either Impella RP or vasoactive treatment (norepinephrine and milrinone) was initiated. Echocardiography and conductance measures were obtained at baseline, when CS was present, and 30, 90, and 180 minutes after induction of CS. Of 20 animals, 14 completed the protocol and were treated with either vasoactive treatment (n=7) or Impella RP (n=7); 6 animals died (3 in each group). In the RV there was a significantly higher LS with the vasoactive treatment compared with Impella RP (-7.6% [4.5] to -6.0% [5.2] vs -4.5% [6.6] to -14.2% [10.6]; <i>P</i><0.006). Left ventricular LS improved with both treatments compared with shock, but with a larger effect (-9.4% [3.2] to -17.9% [3.6]) on LS with vasoactive treatment than Impella RP (-9.8% [3.1] to -12.3% [4.6]; <i>P</i><0.001). We found a significant correlation between stroke work and RV LS (r=-0.60, <i>P</i><0.001) and left ventricular LS (r=-0.62, <i>P</i><0.001). <br /><b>Conclusions:</b><br/>We found significantly higher hemodynamic effects with vasoactive treatment compared with Impella RP in both the RV and left ventricular but at a cost of increased stroke work.</AbstractText><br /><br /><br /><br /><small>J Am Heart Assoc: 03 Feb 2023:e8126; epub ahead of print</small></div>

<div><h4>Changes in absolute flow, myocardial resistance and FFR after chronic total occlusion percutaneous coronary intervention.</h4><i>Khan SA, Alsanjari O, Keulards DCJ, Vlaar PJ, ... Karamasis GV, Davies JR</i><br /><b>Background</b><br />Randomised studies of percutaneous coronary intervention (PCI) in patients with chronic total occlusion (CTO) have shown inconsistent outcomes, suggesting incomplete understanding of this cohort and their coronary physiology. To address this shortcoming, we designed a prospective observational study to measure the recovery of absolute coronary blood flow following successful CTO PCI Aims: We sought to identify patient and procedural characteristics associated with a favourable physiological outcome after CTO PCI.<br /><b>Methods</b><br />Consecutive patients with a CTO subtending viable myocardium underwent PCI utilising contemporary techniques and the hybrid algorithm. Immediately after PCI, and at 3-month follow-up, physiological measurements were performed utilising continuous thermodilution.<br /><b>Results</b><br />A total of 81 patients were included with a mean age 63.6±8.9 years, and 66 (81.5%) were male. Physiological measurements of absolute coronary blood flow in the CTO vessel increased by 30% (p<0.001) and microvascular resistance reduced by 16% (p<0.001) from immediately post-CTO PCI to follow-up assessment. Fractional flow reserve increased by 0.02 (p=0.015) in the same period. Prior coronary artery bypass graft (CABG) and a higher estimated glomerular filtration rate (eGFR) were associated with a larger change in absolute flow. An extraplaque strategy was associated with a smaller change in absolute flow.<br /><b>Conclusions</b><br />Post-CTO PCI, there is a continued augmentation in absolute coronary blood flow and reduction in microvascular resistance from baseline to follow-up at 3 months. Prior CABG and a higher baseline eGFR were predictors of a larger change in absolute coronary flow, whilst an extraplaque final wire path strategy predicted a smaller change. Lastly, the patient characteristics and comorbidities had a larger influence than procedural factors on the observed change in absolute flow.<br /><br /><br /><br /><small>EuroIntervention: 01 Feb 2023; epub ahead of print</small></div>

<div><h4>Contemporary Management Before Chronic Total Occlusion Percutaneous Coronary Interventions: Insights From the Veterans Affairs Clinical Assessment, Reporting, and Tracking Program.</h4><i>Swat SA, Hebbe A, Plomondon ME, Park KE, ... Waldo SW, Valle JA</i><br /><b>Background</b><br />Guidelines recommend maximal antianginal medical therapy before attempted coronary artery chronic total occlusion (CTO) percutaneous coronary intervention (PCI). The degree to which this occurs in contemporary practice is unknown. We aimed to characterize the frequency and variability of preprocedural use of antianginal therapy and stress testing within 3 months before PCI of CTO (CTO PCI) across a nationally integrated health care system.<br /><b>Methods</b><br />We identified patients who underwent attempted CTO PCI from January 2012 to September 2018 within the Veterans Affairs Healthcare System. Patients were categorized by management before CTO PCI: presence of ≥2 antianginals, stress testing, and ≥2 antianginals and stress testing within 3 months of PCI attempt. Multivariable logistic regression and inverse propensity weighting were used for adjustment before trimming, with median odds ratios calculated for variability estimates.<br /><b>Results</b><br />Among 4250 patients undergoing attempted CTO PCI, 40% received ≥2 antianginal medications and 24% underwent preprocedural stress testing. The odds of antianginal therapy with more than one medication before CTO PCI did not change over the years of the study (odds ratio [OR], 1.0 [95% CI, 0.97-1.04]), whereas the odds of undergoing preprocedural stress testing decreased (OR, 0.97 [95% CI, 0.93-0.99]), and the odds of antianginal therapy with ≥2 antianginals and stress testing did not change (OR, 0.98 [95% CI, 0.93-1.04]). Median odds ratios (MOR) showed substantial variability in antianginal therapy across hospital sites (MOR, 1.3 [95% CI, 1.26-1.42]) and operators (MOR, 1.35 [95% CI, 1.26-1.63]). Similarly, preprocedural stress testing varied significantly by site (MOR, 1.68 [95% CI, 1.58-1.81]) and operator (MOR, 1.80 [95% CI, 1.56-2.38]).<br /><b>Conclusions</b><br />Just under half of patients received guideline-recommended management before CTO PCI, with significant site and operator variability. These findings suggest an opportunity to reduce variability in management before CTO PCI.<br /><br /><br /><br /><small>Circ Cardiovasc Qual Outcomes: 01 Feb 2023:e008949; epub ahead of print</small></div>

<div><h4>Clinical Profile and Outcomes of Patients With Pure Aortic Regurgitation Who Underwent Surgical Aortic Valve Replacement.</h4><i>Medranda GA, Molina EJ, Rogers T, Kabir R, ... Satler LF, Waksman R</i><br /><AbstractText>Surgical aortic valve replacement (SAVR) remains the standard of care for patients with chronic severe aortic regurgitation (AR). The introduction of a dedicated transcatheter heart valve for AR has fueled interest in using transcatheter aortic valve replacement to treat patients with isolated AR. We aimed to characterize the profile and outcomes of patients with symptomatic severe AR who underwent isolated SAVR. We conducted a retrospective, observational study of patients who underwent isolated SAVR for symptomatic severe AR at our institution. The primary outcome was in-hospital all-cause mortality. Patients were followed up with 30-day clinical and echocardiographic assessment. A total of 979 patients who underwent SAVR for severe AR between January 2015 and June 2021 were screened for eligibility, of whom 112 patients (11.4%) underwent isolated SAVR for symptomatic severe AR and were included in this analysis. Approximately 25% of patients were deemed to be at intermediate or high risk (n = 26 of 112). The primary outcome occurred in 2.7% of patients (n = 3 of 112). In-hospital stroke occurred in 2.7% of patients (n = 3 of 112), and new-onset atrial fibrillation occurred in 32.1% (n = 36 of 112). At 30-day follow-up, all-cause mortality occurred in 3.6% of patients (n = 4 of 112), and 0.8% (1 of 112) had >mild AR. In conclusion, in a tertiary referral center, the number of patients who underwent isolated SAVR for pure AR represented a small fraction of the overall SAVR patients. The vast majority were low risk and younger when compared with patients with severe aortic stenosis. SAVR yielded excellent short-term mortality and echocardiographic improvements.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Infective Endocarditis After Transcatheter Aortic Valve Replacement: JACC State-of-the-Art Review.</h4><i>Del Val D, Panagides V, Mestres CA, Miró JM, Rodés-Cabau J</i><br /><AbstractText>Infective endocarditis (IE) is a rare but serious complication following transcatheter aortic valve replacement (TAVR). Despite substantial improvements in the TAVR procedure (less invasive) and its expansion to younger and healthier patients, the incidence of IE after TAVR remains stable, with incidence rates similar to those reported after surgical aortic valve replacement. Although IE after TAVR is recognized as a subtype of prosthetic valve endocarditis, this condition represents a particularly challenging scenario given its unique clinical and microbiological profile, the high incidence of IE-related complications, the uncertain role of cardiac surgery, and the dismal prognosis in most patients with TAVR-IE. The number of TAVR procedures is expected to grow exponentially in the coming years, increasing the number of patients at risk of developing this life-threatening complication. Therefore, a detailed understanding of this disease and its complications will be essential to improve clinical outcomes.</AbstractText><br /><br />Copyright © 2023 American College of Cardiology Foundation.

<div><h4>Analysis of Coronary Arterial Aneurysm Regression in Patients With Kawasaki Disease by Aneurysm Severity: Factors Associated With Regression.</h4><i>Kato T, Miura M, Kobayashi T, Kaneko T, ... Fuse S, Z‐Score Project 2nd Stage Study Group *</i><br /><AbstractText><br /><b>Background:</b><br/>Coronary arterial aneurysms (CAAs) associated with Kawasaki disease (KD) significantly affect prognosis. However, the clinical course of CAAs and factors associated with CAA regression have not been well analyzed. Methods and Results The cohort of the Z-Score 2nd Project Stage study, a multicenter, retrospective, cohort study involving 44 institutions in Japan including 1006 patients with KD, was examined. CAAs were classified by the <i>z</i> score of their internal diameter in the acute phase: small (<i>z</i><5), medium (5≤<i>z</i><10), and large (<i>z</i>≥10). The lower limit of small CAA was based on the Japanese Ministry of Health, Labour and Welfare criteria. In the right coronary artery, the CAA regression rates 10 years after diagnosis were 95.5% for small, 83.2% for medium, and 36.3% for large. In the proximal left anterior descending artery, the regression rates 10 years after diagnosis were 95.3% for small, 80.1% for medium, and 28.8% for large. Cox regression analysis showed that diagnosis under the age of 1 year and onset of KD in 2010 to 2012 for the right coronary artery and the left anterior descending artery, and female for the right coronary artery were significantly associated with a high regression rate, whereas large CAAs for the right coronary artery and the left anterior descending artery were significantly associated with a low regression rate. <br /><b>Conclusions:</b><br/>The current study, the largest Japanese study of its kind, found that small aneurysm, recent onset, and diagnosis under the age of 1 year predict regression, and that even giant aneurysms could regress. These data may contribute to long-term management of coronary aneurysms.

<div><h4>Health Status Outcomes in Older Adults Undergoing Chronic Total Occlusion Percutaneous Coronary Intervention.</h4><i>Nguyen DD, Gosch KL, El-Zein R, Chan PS, ... Salisbury AC, OPEN‐CTO Study Group *</i><br /><AbstractText><br /><b>Background:</b><br/>Although chronic total occlusions (CTOs) are common in older adults, they are less likely to be offered CTO percutaneous coronary intervention for angina relief than younger adults. The health status impact of CTO percutaneous coronary intervention in adults aged ≥75 years has not been studied. We sought to compare technical success rates and angina-related health status outcomes at 12 months between adults aged ≥75 and <75 years in the OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion) registry. Methods and Results Angina-related health status was assessed with the Seattle Angina Questionnaire (score range 0-100, higher scores denote less angina). Technical success rates were compared using hierarchical modified Poisson regression, and 12-month health status was compared using hierarchical multivariable linear regression between adults aged ≥75 and <75 years. Among 1000 participants, 19.8% were ≥75 years with a mean age of 79.5±4.1 years. Age ≥75 years was associated with a lower likelihood of technical success (adjusted risk ratio=0.92 [95% CI, 0.86-0.99; <i>P</i>=0.02]) and numerically higher rates of in-hospital major adverse cardiovascular events (9.1% versus 5.9%, <i>P</i>=0.10). There was no difference in Seattle Angina Questionnaire Summary Score at 12 months between adults aged ≥75 and <75 years (adjusted difference=0.9 [95% CI, -1.4 to 3.1; <i>P</i>=0.44]). <br /><b>Conclusions:</b><br/>Despite modestly lower success rates and higher complication rates, adults aged ≥75 years experienced angina-related health status benefits after CTO-percutaneous coronary intervention that were similar in magnitude to adults aged <75 years. CTO percutaneous coronary intervention should not be withheld based on age alone in otherwise appropriate candidates.</AbstractText><br /><br /><br /><br /><small>J Am Heart Assoc: 31 Jan 2023:e027915; epub ahead of print</small></div>

<div><h4>Intermediate Follow-Up of Balloon-Expandable Versus Self-Expanding Transcatheter Aortic Valve Implantation in Patients With Small Aortic Annuli.</h4><i>Mosleh W, Memon S, Hoover NE, Mather JF, ... Hashim S, McKay RG</i><br /><AbstractText>The clinical impact of prosthesis-patient mismatch (PPM) in patients with small aortic annuli who underwent transcatheter aortic valve (AV) implantation with either balloon-expandable (BE) or self-expanding (SE) valves remains controversial. We assessed in-hospital and intermediate clinical outcomes in 573 patients with transfemoral transcatheter AV implantation with a small AV annulus, defined as an AV annulus area ≤430 mm<sup>2</sup>. A total of 337 patients treated with a 23-mm BE valve (SAPIEN 3, Ultra) were compared with 236 patients treated with a 26-mm SE valve (Evolut series). Valve-in-valve cases were excluded, and late echo follow-up (mean 674 ± 438 days) was assessed in a subset of 292 patients (51.0%). Well-matched BE and SE cohorts did not differ with respect to major in-hospital outcomes, other than a borderline increase in vascular complications and composite bleeding in patients with SE. Patients with BE had a higher incidence of severe PPM on discharge echocardiography (16.9% vs 6.8%, p <0.002). The mean AV gradient at 30 days was higher for patients with BE (12.2 ± 4.2 vs 6.2 ± 7.9 mm Hg, p <0.001) and at late follow-up (14.0 ± 8.2 vs 7.2 ± 3.5 mm Hg, p <0.001). The follow-up left ventricular ejection fraction and incidence of >mild aortic insufficiency were similar. All-cause mortality for the 2 cohorts was similar, with an overall mean (95% confidence interval) survival time of 61.2 months (57.8 to 64.5; p = 0.98). There were no significant survival differences between combined patients with BE and SE with no, moderate, or severe PPM, with an overall mean (95% confidence interval) survival time of 32.5 (30.5 to 34.5) months combining valve types (p = 0.23). In conclusion, despite an increased incidence of PPM with higher mean AV gradients that persist on late echocardiography in the BE cohort, patients with BE and SE with small aortic annuli have similar clinical outcomes at intermediate follow-up. Moderate and severe PPM had no impact on survival at a mean follow-up of 32.5 months.</AbstractText><br /><br />Copyright © 2023 The Author(s). Published by Elsevier Inc.

<div><h4>Endothelial dysfunction predicts bleeding and cardiovascular death in acute coronary syndrome.</h4><i>Yoshii T, Matsuzawa Y, Kato S, Sato R, ... Tamura K, Kimura K</i><br /><b>Backgrounds</b><br />Recently, there has been increasing awareness that bleeding may lead to adverse outcomes. Endothelial dysfunction is associated with increased risk of cardiovascular and bleeding events. This study aimed to investigate the association of endothelial dysfunction with major bleeding and specific causes of death in addition to major adverse cardiovascular events in patients with acute coronary syndrome.<br /><b>Methods</b><br />This single-centre retrospective observational study was conducted at a tertiary-care hospital; patients with acute coronary syndrome were included between June 2010 and November 2014 (median follow-up, 6.1 years). The reactive hyperaemia index was assessed before their discharge; reactive hyperaemia index <1.67 was defined as endothelial dysfunction. The main outcomes were the incidence of major bleeding, all-cause death, cardiovascular death, non-cardiovascular death, resuscitated cardiac arrest, non-fatal myocardial infarction, non-fatal stroke, and hospitalisation for heart failure.<br /><b>Results</b><br />Among the included 674 patients with acute coronary syndrome, 264 (39.2%) had endothelial dysfunction. Multivariable Cox-hazard analyses revealed an independent predictive value of endothelial dysfunction for major bleeding (hazard ratio 2.29, 95% confidence interval 1.17-4.48, P = 0.016) and major adverse cardiovascular events (hazard ratio 2.04, 95% confidence interval 1.43-2.89, P < 0.001). The endothelial dysfunction group patients had a 2.5-fold greater risk of cardiovascular death; however, no association was found with non-cardiovascular death.<br /><b>Conclusion</b><br />Endothelial dysfunction assessed using reactive hyperaemia index predicted future major cardiovascular event as well as major bleeding and cardiovascular death in patients with acute coronary syndrome.<br /><br />Copyright © 2023.

<div><h4>Prevalence and patterns of in-stent neoatherosclerosis in lower extremity artery disease.</h4><i>Müller A, Bradaric C, Kafka A, Joner M, ... Ibrahim T, Koppara T</i><br /><b>Background</b><br />In-stent restenosis (ISR) is responsible for a rapid decline of vessel patency after stenting. To date, little is known about the role of in-stent neoatherosclerosis (NA) in stent failure in lower limb arteries.<br /><b>Aims</b><br />This study aimed to determine the prevalence and patterns of in-stent NA in patients with symptomatic ISR of the lower extremity vasculature using intravascular optical coherence tomography (OCT) imaging.<br /><b>Methods</b><br />Patients underwent endovascular revascularisation for ISR including angiography and OCT imaging. NA was defined as the presence of at least 1 fibroatheroma or fibrocalcific plaque within the neointima of a stented segment.<br /><b>Results</b><br />Using OCT, we imaged 24 symptomatic patients with lower extremity artery disease (LEAD), with a total of 30 ISR in the lower limbs, prior to their scheduled endovascular interventions. NA formation was observed in 23 (76.7%) lesions, while all stents with an implant duration >5 years (n=8) showed signs of NA. The time from stent implantation to OCT was significantly increased in lesions with NA (p=0.002). Lesions without NA had a significantly shorter duration from index procedure to OCT than those with ≥50 percent (n=9; p=0.003) or <50 percent (n=14; p=0.015) of frames exhibiting signs of NA. NA was predominantly characterised by fibroatheroma with thick fibrous caps with or without calcification.<br /><b>Conclusions</b><br />In-stent NA is frequently identified by OCT imaging after endovascular therapy in lower limb arteries; this increased both in frequency and extent the longer the duration since implantation. Our findings indicate an active atherosclerotic process that may need tailored mitigation strategies.<br /><br /><br /><br /><small>EuroIntervention: 30 Jan 2023; epub ahead of print</small></div>

<div><h4>The impact of baseline transmitral diastolic mean gradient on left atrial pressure reduction in patients undergoing transcatheter mitral valve edge-to-edge repair.</h4><i>Lugo-Fagundo N, Pierre K, Adedinsewo D, Simard T, ... Guerrero M, El Sabbagh A</i><br /><b>Background</b><br />Elevated transmitral gradient post transcatheter mitral valve edge-to-edge repair (TEER) has been associated with worse outcomes. Whether an elevated baseline transmitral diastolic mean gradient (MG) ≥5 mmHg is associated with hemodynamic outcomes after TEER is unknown.<br /><b>Methods</b><br />A total of 164 consecutive patients undergoing TEER at Mayo Clinic between June 2014 and May 2018 were analyzed in this retrospective study. Baseline demographics, as well as clinical, echocardiographic, and procedural data were obtained. Data on direct left atrial pressure (LAP) before and after TEER were recorded. Logistic regression models were constructed to evaluate the association between preprocedure transmitral diastolic mean gradient (pre-MG) and (1) improvement in LAP following TEER, (2) postprocedure transmitral diastolic mean gradient (post-MG). A decrease in LAP post TEER was considered an improvement in hemodynamic response. Pre-MG was categorized as: ≥5 and <5 mmHg.<br /><b>Results</b><br />Median age of the cohort was 81.5 years (Q1: 76.3, Q3: 87) and 34% were female. At baseline, median transmitral diastolic MG was 4 mmHg (Q1: 3, Q3: 5) and median LAP was 19 mmHg (Q1:16, Q3: 23.5). In a multivariable model, adjusted for age and sex, patients with pre-MG ≥ 5 mmHg were less likely to see an improvement in LAP post TEER (adjusted odds ratio [aOR]: 0.22, 95% confidence interval [CI]: 0.09, 0.55; p = 0.001) and more likely to have elevated post-MG (aOR; 7.08, 95% CI: 2.93, 17.13; p < 0.001).<br /><b>Conclusion</b><br />Higher pre-MG (≥5 mmHg) was associated with a lower reduction in LAP and higher residual transmitral gradient following TEER suggesting other potential contributors to increased LAP besides mitral regurgitation as a cause of elevated baseline MG.<br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 30 Jan 2023; epub ahead of print</small></div>

<div><h4>Impact of technique on bifurcation stent outcomes in the European Bifurcation Club Left Main Coronary Trial.</h4><i>Arunothayaraj S, Lassen JF, Clesham GJ, Spence MS, ... Louvard Y, Hildick-Smith D</i><br /><b>Background</b><br />Techniques for provisional and dual-stent left main bifurcation stenting require optimization.<br /><b>Aim</b><br />To identify technical variables influencing procedural outcomes and periprocedural myocardial infarction following left main bifurcation intervention.<br /><b>Methods</b><br />Procedural and outcome data were analyzed in 438 patients from the per-protocol cohort of the European Bifurcation Club Left Main Trial (EBC MAIN). These patients were randomized to the provisional strategy or a compatible dual-stent extension (T, T-and-protrude, or culotte).<br /><b>Results</b><br />Mean age was 71 years and 37.4% presented with an acute coronary syndrome. Transient reduction of side vessel thrombolysis in myocardial infarction flow occurred after initial stent placement in 5% of procedures but was not associated with periprocedural myocardial infarction. Failure to rewire a jailed vessel during any strategy was more common when jailed wires were not used (9.5% vs. 2.5%, odds ratio [OR]: 6.4, p = 0.002). In the provisional cohort, the use of the proximal optimization technique was associated with less subsequent side vessel intervention (23.3% vs. 41.9%, OR: 0.4, p = 0.048). Side vessel stenting was predominantly required for dissection, which occurred more often following side vessel preparation (15.3% vs. 4.4%, OR: 3.1, p = 0.040). Exclusive use of noncompliant balloons for kissing balloon inflation was associated with reduced need for side vessel intervention in provisional cases (20.5% vs. 38.5%, OR: 0.4, p = 0.013), and a reduced risk of periprocedural myocardial infarction across all strategies (2.9% vs. 7.7%, OR: 0.2, p = 0.020).<br /><b>Conclusion</b><br />When performing provisional or compatible dual-stent left main bifurcation intervention, jailed wire use is associated with successful jailed vessel rewiring. Side vessel preparation in provisional patients is linked to increased side vessel dissection requiring stenting. Use of the proximal optimization technique may reduce the need for additional side vessel intervention, and noncompliant balloon use for kissing balloon inflation is associated with a reduction in both side vessel stenting and periprocedural myocardial infarction.<br /><b>Clinical trial registration</b><br />ClinicalTrials.gov Identifier NCT02497014.<br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 29 Jan 2023; epub ahead of print</small></div>

<div><h4>Iliofemoral artery predilation prior to transfemoral transcatheter aortic valve implantation in patients with aortic valve stenosis and advanced peripheral artery disease.</h4><i>Alvarez-Covarrubias HA, Joner M, Cassese S, Warmbrunn M, ... Kastrati A, Xhepa E</i><br /><b>Objectives</b><br />To investigate the feasibility and safety of percutaneous transluminal angioplasty (PTA) of the iliofemoral arteries (IFA) before transfemoral transcatheter aortic valve implantation (Tf-TAVI) in patients with advanced peripheral artery disease (PAD).<br /><b>Background</b><br />Although Tf-TAVI represents the access of choice, alternative vascular access routes are preferred for patients displaying advanced PAD. PTA of the IFA represents a less invasive option, broadening the spectrum of patients eligible for Tf-TAVI.<br /><b>Methods</b><br />All patients requiring PTA of the IFA before Tf-TAVI, between 2012 and 2021, were included. Primary efficacy endpoint was the rate of successful transcatheter heart valve (THV) delivery and implantation. Primary safety endpoint was the rate of PTA and access-site-related vascular complications, procedural- and in-hospital complications.<br /><b>Results</b><br />Among 2726 Tf-TAVI procedures, 59 patients required IFA predilation. Successful THV delivery and implantation was achieved in 57 (96.6%) patients, respectively. Sheath placement was achieved in 59 (100%) patients with only one minor dissection and no major vascular complications following iliofemoral PTA. Regarding access site complications, two (3.4%) vessel perforations and one (1.7%) vessel rupture were observed, with eight (13.5%) patients requiring unplanned endovascular interventions. There was one intraprocedural death due to THV-induced vessel laceration, while in-hospital all-cause mortality was 8.5% in the present high-risk patient cohort.<br /><b>Conclusions</b><br />Predilation of IFA is safe and effective in patients with advanced PAD. Careful preprocedural planning is paramount in improving procedural safety and efficacy.

Park K, Kim HS</i><br /><b>Aims</b><br />The aim of this study was to evaluate the efficacy and safety of prasugrel-dose de-escalation therapy in patients with diabetes mellitus (DM)-acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI).<br /><b>Methods and results</b><br />This was a post-hoc analysis of the HOST-REDUCE-POLYTECH-ACS randomized trial. The efficacy and safety of prasugrel dose de-escalation therapy (prasugrel 5 mg daily) were compared with conventional therapy (prasugrel 10 mg daily) in patients with DM. The primary endpoint was net adverse clinical events (NACE), defined as a composite of all-cause death, nonfatal myocardial infarction (MI), stent thrombosis (ST), clinically driven revascularization, stroke, and BARC class ≥ 2 bleeding events. The secondary ischemic outcome was major adverse cardiovascular and cerebrovascular events (MACE), defined as the composite of cardiac death, nonfatal MI, ST, or ischemic stroke. Of 2 338 patients randomized, 990 had DM. The primary endpoint of NACE occurred in 38 patients (7.6%) receiving prasugrel dose de-escalation and in 53 patients (11.3%) receiving conventional therapy among patients with DM (HR 0.66; 95% CI 0.43-0.99; P = 0.049). Prasugrel dose de-escalation as compared with conventional therapy did not increase the risk of ischemic events (HR 1.03; 95% CI 0.56-1.88; P = 0.927) but decreased BARC class ≥ 2 bleeding in patients with DM (HR 0.44; 95% CI 0.23-0.84; P = 0.012).<br /><b>Conclusion</b><br />Prasugrel dose de-escalation compared with conventional therapy may reduce the risk of net clinical outcomes, mostly driven by a reduction in bleeding without an increase in ischemic events in patients with DM.<br /><br />© The Author(s) 2023.

<div><h4>Meta-Analysis on the Safety and Efficacy of Transradial Approach in Chronic Total Occlusion Percutaneous Coronary Intervention.</h4><i>Nguyen DV, Nguyen QN, Pham HM, Le TX, Nguyen HTT</i><br /><AbstractText>The aim of this study was to compare the efficacy and safety of transradial approach (TRA) in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) with the efficacy and safety of transfemoral approach (TFA). We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies (OS) reporting the outcomes of TRA versus TFA in CTO PCI. The primary end point was procedural success. Secondary end points included access-site complications, in-hospital adverse events, procedural efficacy outcomes, and 30-day all-cause mortality. A total of 28,754 CTO PCI cases from 19 studies were included (2 RCTs and 17 OS). The pooled mean J-CTO score is 2.3. The main analysis showed a trend toward a higher success rate for TRA (odds ratio [OR] 1.17, 95% confidence interval [CI] 1.00 to 1.38), but this was not the case in the secondary analysis, which included only RCTs and OS with moderate risk of bias (OR 0.99, 95% CI 0.81 to 1.22). TRA was associated with significant reductions in access-site complications (OR 0.33, 95% CI 0.24 to 0.45) and major bleeding (OR 0.34, 95% CI 0.20 to 0.59), and a similar risk of other in-hospital adverse events and 30-day mortality (p >0.05) to that of TFA. Moreover, there was less fluoroscopy time (minutes) and contrast volume use (ml) in the transradial CTO PCI (mean difference: -6.19 [-10.98 to -1.40] and -22.14[-34.56 to -9.72], respectively). In conclusion, the transradial PCI in appropriate CTO lesions was associated with a lower incidence of access-site complications/major bleeding than was TFA and a similar other periprocedural complications rate, without compromising procedural success.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Clinical and angiographic features of SCAD type 4.</h4><i>Mori R, Macaya-Ten F, Giacobbe F, Salinas P, ... Cerrato E, Escaned J</i><br /><b>Introduction</b><br />The angiographic type 4 in SCAD is described as a total occlusion of the coronary artery and its management may differ according to its clinical presentation. We previously have observed that these patients present a low incidence of adverse events. Our objective was to describe clinical and angiographic characteristics of this condition, according to its initial management in the DISCO registry.<br /><b>Methods</b><br />We conducted an observational study of consecutive SCAD patients from 26 centres of Italy and Spain (DISCO registry). Angiotype 4 SCAD cases were selected and classified according to the initial treatment chosen: conservative management vs. percutaneous coronary intervention (PCI). Clinical and angiographic characteristics were compared.<br /><b>Results</b><br />We recruited 81 (mean age 52.6 ± 11 years) patients with SCAD angiotype 4 out of 302 patients of the DISCO registry. Thirty-eight (46.9%) patients received conservative management and 43 (53.1%) received PCI. Nearly all patients undergoing PCI had ST-segment elevation (93% vs 47.4%, p < 0.0001), the left anterior descending artery (LAD) was more commonly involved (67.4% vs. 42.1%, p = 0.006), and they had more frequent proximal segment involvement (25.6% vs 2.7%, p = 0.004) and longer lesions (46.5 ± 23.2 mm vs 26.4 ± 18.8 mm, p = 0.017). On the other hand, non-ST-segment elevation myocardial infarction (52.6% vs 2.3%, p = 0.001) and isolated involvement of secondary branches (55.3 vs 4.7, p < 0.0001) were more common in the conservative management group.<br /><b>Conclusions</b><br />Patients with SCAD angiotype 4 who underwent PCI had a higher frequency of STEMI and involvement of proximal and longer coronary segments, particularly affecting the left anterior descending artery. NSTEMI and isolated involvement of secondary branches were more frequently found in those managed conservatively.<br /><br />Copyright © 2023 Elsevier Ireland Ltd.

AD was defined as a new-onset dissected layer of the aortic wall and diagnosed by aortography, computed tomography, or transesophageal echocardiography.<br /><b>Results</b><br />Five of the six type A AD cases (83%) were detected during TAVR versus only one of the seven type B AD cases (14%). Four of the seven type B AD cases (57%) were asymptomatic and incidentally detected on computed tomography. The presumed causes of AD were injury by the delivery sheath (39%), delivery catheter (23%), valve implantation (15%), stent edge (15%), and pre-dilation balloon (8%). Complicated AD occurred in only one patient (8%). Considering the patient\'s age and prohibitive surgical risk, all patients were treated conservatively and free of any aortic-related deaths or interventions during a follow-up of 1087 days.<br /><b>Conclusions</b><br />TAVR-related AD is a rare but life-threatening condition that may be underdiagnosed. Its optimal therapy remains unclear, and conservative management might be an option for selected patients. Further studies are needed to elucidate the incidence, risk factors, effective screening, optimal therapy, and outcomes of TAVR-related AD.<br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 26 Jan 2023; epub ahead of print</small></div>

Potential mechanisms include greater exposure to inflammatory cytokines, reactive oxygen species and oxidised low-density lipoproteins, as acute strenuous physical activity has been found to enhance their systemic release. Other possibilities include post-exercise elevations in circulating parathyroid hormone, which can modify the amount and morphology of calcific plaque, and long-term exposure to non-laminar blood flow within the coronary arteries during vigorous physical activity, particularly in individuals with pre-existing atherosclerosis. Further, although the association has only been identified in men, the role of testosterone in this process remains unclear. This brief review discusses the association between high-volume endurance exercise and CAC in older men, elaborates on the potential mechanisms underlying the increased calcification, and provides clinical implications and recommendations for those at risk.</AbstractText><br /><br />© Author(s) (or their employer(s)) 2023.

<div><h4>Routine cerebral embolic protection in transcatheter aortic valve implantation: rationale and design of the randomised British Heart Foundation PROTECT-TAVI trial.</h4><i>Kharbanda RK, Perkins AD, Kennedy J, Banning AP, ... Stables R, Clayton T</i><br /><AbstractText>Transcatheter aortic valve implantation (TAVI) is an established treatment for aortic stenosis. Cerebral embolic protection (CEP) devices may impact periprocedural stroke by capturing debris destined for the brain. However, there is a lack of high-quality randomised trial evidence supporting the use of CEP during TAVI. The British Heart Foundation (BHF) PROTECT-TAVI trial will address whether the routine use of CEP reduces the incidence of stroke in patients undergoing TAVI. BHF PROTECT-TAVI is a prospective, open-label, outcome-adjudicated, multicentre randomised controlled trial. The trial is open to all adult patients scheduled for TAVI at participating specialist cardiac centres across the United Kingdom who are able to receive the CEP device. The trial will recruit 7,730 participants. Participants will be randomised in a 1:1 ratio to undergo TAVI with CEP or TAVI without CEP (standard of care). The primary outcome is the incidence of stroke at 72 hours post-TAVI. Key secondary outcomes include the incidence of stroke and all-cause mortality up to 12 months post-TAVI, disability and cognitive outcomes, stroke severity, access site complications and a health economics analysis. The sample size of 7,730 participants has 80% power to detect a 33% relative risk reduction from a 3% incidence of the primary outcome in the controls. Trial recruitment commenced in October 2020. As of October 2022, 3,068 patients have been enrolled. BHF PROTECT-TAVI is designed to provide definitive evidence on the clinical efficacy and cost-effectiveness of using routine CEP with the SENTINEL device to reduce stroke in TAVI.</AbstractText><br /><br /><br /><br /><small>EuroIntervention: 26 Jan 2023; epub ahead of print</small></div>

Brilakis ES, Sandoval Y</i><br /><b>Background</b><br />There is limited data on the impact of a second attending operator on chronic total occlusion (CTO) percutaneous coronary intervention (PCI) outcomes.<br /><b>Methods</b><br />We analyzed the association between multiple operators (MOs) (>1 attending operator) and procedural outcomes of 9296 CTO PCIs performed between 2012 and 2021 at 37 centers.<br /><b>Results</b><br />CTO PCI was performed by a single operator (SO) in 85% of the cases and by MOs in 15%. Mean patient age was 64.4 ± 10 years and 81% were men. SO cases were more complex with higher Japan-CTO (2.38 ± 1.29 vs. 2.28 ± 1.20, p = 0.005) and Prospective Global Registry for the Study of Chronic Total Occlusion Intervention scores (1.13 ± 1.01 vs. 0.97 ± 0.93, p < 0.001) compared with MO cases. Procedural time (131 [87, 181] vs. 112 [72, 167] min, p < 0.001), fluoroscopy time (49 [31, 76] vs. 42 [25, 68] min, p < 0.001), air kerma radiation dose (2.32 vs. 2.10, p < 0.001), and contrast volume (230 vs. 210, p < 0.001) were higher in MO cases. Cases performed by MOs and SO had similar technical (86% vs. 86%, p = 0.9) and procedural success rates (84% vs. 85%, p = 0.7), as well as major adverse complication event rates (MACE 2.17% vs. 2.42%, p = 0.6). On multivariable analyses, MOs were not associated with higher technical success or lower MACE rates.<br /><b>Conclusion</b><br />In a contemporary, multicenter registry, 15% of CTO PCI cases were performed by multiple operators.

<div><h4>Impact of complex percutaneous coronary intervention features on clinical outcomes in patients with or without chronic kidney disease.</h4><i>Chen H, Spirito A, Sartori S, Nicolas J, ... Dangas G, Mehran R</i><br /><b>Background</b><br />Patients with chronic kidney disease (CKD) are at higher risk of ischemic and bleeding events after percutaneous coronary intervention (PCI). Complex PCI (CPCI) is associated with higher rates of ischemic complications. Whether CPCI confers an additive risk of adverse events in CKD patients is unclear.<br /><b>Methods</b><br />Patients who underwent PCI at a single tertiary-care-center between 2012 and 2019 were stratified by CKD status and CPCI. The primary outcome was major adverse cardiac events (MACE), a composite of all-cause death, myocardial infarction (MI), and target-vessel revascularization (TVR) at 1-year follow-up. Secondary outcomes included the individual components of the primary outcome and major bleeding.<br /><b>Results</b><br />Out of 15,071 patients, 4537 (30.1%) had CKD and 10,534 (69.9%) had no CKD. Patients undergoing CPCI were 1151 (25.4%) and 2983 (28.3%) in the two cohorts, respectively. At one year, CPCI compared with no CPCI was associated with higher risk of MACE in both CKD (Adj. HR 1.72, 95% confidence interval [CI] 1.45-2.06, p < 0.001) and no-CKD patients (Adj. hazard ratios [HR] 2.19, 95% CI 1.91-2.51, p < 0.001; p of interaction 0.057), determined by an excess of death, MI and TVR in CKD patients and of TVR and MI only in no-CKD. CPCI was related with a consistent increase of major bleeding in the CKD (Adj. HR 1.49, 95% CI 1.18-1.87, p < 0.001) and no-CKD group (Adj. HR 1.23, 95% CI 0.98-1.54, p = 0.071, p of interaction 0.206).<br /><b>Conclusion</b><br />At 1-year follow-up, CPCI was associated with higher risk of MACE and major bleeding irrespective of concomitant CKD.

Abstract
<div><h4>Novel dual guiding catheter technique for kissing balloon inflation in percutaneous coronary intervention for bifurcated chronic total occlusive lesion.</h4><i>Kawamura Y, Yoshimachi F, Kasai S, Ikari Y</i><br /><AbstractText>Traditionally, two bigger-sized guiding catheters (GCs) via the femoral artery have been used in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO). However, those GCs are associated with an increased incidence of bleeding. Therefore, the use of smaller GCs (e.g., 5-Fr) may lessen the invasiveness of this procedure. However, the use of 5-Fr GCs in PCI is complicated by device limitations. A novel technique was developed to overcome the challenges with regard to kissing balloon inflation. This approach involves simultaneous balloon inflation through a dual 5-Fr GC technique for CTO-PCI. In our hospital, this technique was successfully performed in 9 cases of CTO with 10 bifurcated lesions (including four left main-related bifurcations). During the study period, there was no requirement for an additional invasive procedure or occurrence of complications related to the PCI procedure. This technique may be a good option for performing KBI during CTO-PCI through the use of two 5-Fr GCs.</AbstractText><br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 24 Jan 2023; epub ahead of print</small></div>

<div><h4>Mitral valve transcatheter edge-to-edge repair.</h4><i>Hausleiter J, Stocker TJ, Adamo M, Karam N, Swaans MJ, Praz F</i><br /><AbstractText>Mitral regurgitation (MR) is the most prevalent valvular heart disease and, when left untreated, results in reduced quality of life, heart failure, and increased mortality. Mitral valve transcatheter edge-to-edge repair (M-TEER) has matured considerably as a non-surgical treatment option since its commercial introduction in Europe in 2008. As a result of major device and interventional improvements, as well as the accumulation of experience by the interventional cardiologists, M-TEER has emerged as an important therapeutic strategy for patients with severe and symptomatic MR in the current European and American guidelines. Herein, we provide a comprehensive up-do-date overview of M-TEER. We define preprocedural patient evaluation and highlight key aspects for decision-making. We describe the currently available M-TEER systems and summarise the evidence for M-TEER in both primary mitral regurgitation (PMR) and secondary mitral regurgitation (SMR). In addition, we provide recommendations for device selection, intraprocedural imaging and guiding, M-TEER optimisation and management of recurrent MR. Finally, we provide information on major unsolved questions and \"grey areas\" in M-TEER.</AbstractText><br /><br /><br /><br /><small>EuroIntervention: 23 Jan 2023; 18:957-976</small></div>

<div><h4>The 5 Phenotypes of Tricuspid Regurgitation: Insight From Cluster Analysis of Clinical and Echocardiographic Variables.</h4><i>Anand V, Scott CG, Hyun MC, Lara-Breitinger K, ... Schulte PJ, Pislaru SV</i><br /><b>Background</b><br />The recent morphologic classification of tricuspid regurgitation (TR) (ie, atrial functional, ventricular functional, lead related, and primary) does not capture underlying comorbidities and clinical characteristics.<br /><b>Objectives</b><br />This study aimed to identify the different phenotypes of TR using unsupervised cluster analysis and to determine whether differences in clinical outcomes were associated with these phenotypes.<br /><b>Methods</b><br />We included 13,611 patients with ≥moderate TR from January 2004 to April 2019 in the final analyses. Baseline demographic, clinical, and echocardiographic data were obtained from electronic medical records and echocardiography reports. Ward\'s minimum variance method was used to cluster patients based on 38 variables. The analysis of all-cause mortality was performed using the Kaplan-Meier method, and groups were compared using log-rank test.<br /><b>Results</b><br />The mean age of patients was 72 ± 13 years, and 56% were women. Cluster analysis identified 5 distinct phenotypes: cluster 1 represented \"low-risk TR\" with less severe TR, a lower prevalence of right ventricular enlargement, atrial fibrillation, and comorbidities; cluster 2 represented \"high-risk TR\"; and clusters 3, 4, and 5 represented TR associated with lung disease, coronary artery disease, and chronic kidney disease, respectively. Cluster 1 had the lowest mortality followed by clusters 2 (HR: 2.22 [95% CI: 2.1-2.35]; P < 0.0001) and 4 (HR: 2.19 [95% CI: 2.04-2.35]; P < 0.0001); cluster 3 (HR: 2.45 [95% CI: 2.27-2.65]; P < 0.0001); and, lastly, cluster 5 (HR: 3.48 [95% CI: 3.07-3.95]; P < 0.0001).<br /><b>Conclusions</b><br />Cluster analysis identified 5 distinct novel subgroups of TR with differences in all-cause mortality.

<div><h4>The Relationship Between Hospital Stroke Center Designation and TVT Reported Stroke: The Michigan TAVR Experience.</h4><i>Grossman PM, Sukul D, Lall SC, Villablanca PA, ... Patel HJ, Deeb GM</i><br /><b>Background</b><br />The 30-day rate of stroke after transcatheter aortic valve replacement (TAVR) has been suggested as a hospital quality metric. Thirty-day stroke rates for nonsurgical, high, and moderate-risk TAVR trials were 3.4% to 6.1%, whereas those in the national Transcatheter Valve Therapy (TVT) Registry for the same patient population were much lower. Hospital comprehensive stroke center (CSC) is the highest designation for integrated acute stroke recognition, management, and care.<br /><b>Objectives</b><br />Using Michigan TVT data, we assessed whether in-hospital post-TAVR stroke rates varied between CSC and non-CSC institutions.<br /><b>Methods</b><br />TVT data submitted from the 22 Michigan Transcatheter Aortic Valve Replacement Collaborative participating institutions between January 1, 2016, and June 30, 2019, were included (N = 6,231). Bayesian hierarchical regression models accounting for patient clinical characteristics and hospital clustering were fitted to assess the association between hospital CSC accreditation and in-hospital post-TAVR stroke. Adjusted ORs and 95% credible intervals were estimated. The University of Michigan Institutional Review Board has waived the need for the approval of studies based on the data collected by the Blue Cross Blue Shield of Michigan Cardiovascular Consortium registry.<br /><b>Results</b><br />There were 3,882 (62.3%) patients at 9 CSC sites and 2,349 (37.7%) patients at 13 non-CSC sites. CSC sites had significantly higher rates of in-hospital post-TAVR stroke (CSC: 2.65% vs non-CSC: 1.15%; P < 0.001). After adjustment, patients who underwent TAVR at a CSC hospital had a significantly higher risk of in-hospital stroke (adjusted OR: 2.21; 95% CI: 1.03-4.62). However, CSC designation was not significantly associated with other important post-TAVR clinical outcomes including 30-day mortality.<br /><b>Conclusions</b><br />Reported Michigan Transcatheter Aortic Valve Replacement Collaborative TVT stroke rates were significantly higher at sites with Joint Hospital Commission stroke designation status; however, other reported important clinical outcomes did not differ significantly based on this designation. CSC designation is a possible factor in stroke rate detection differences between TAVR institutions and might be a factor in the observed differences in stroke rates between TAVR trials and those reported in TVT. In addition, these data suggest that comparison between hospitals based on post-TAVR stroke rates is potentially problematic.<br /><br />Copyright © 2023 American College of Cardiology Foundation.

Olesen JB, Fosbøl EL</i><br /><b>Background</b><br />Loss of autonomy associated with nursing home admission (NHA) is a concern for patients. Yet the incidence of NHA after transcatheter aortic valve replacement (TAVR) is unknown.<br /><b>Objectives</b><br />The aim of this study was to investigate the incidence and factors associated with NHA following TAVR compared with the general population.<br /><b>Methods</b><br />Through Danish registries, patients alive at discharge after TAVR were identified from January 2014 to October 2021. Patients were matched 1:5 on sex, age, and calendar year to the general population. The 3-year cumulative incidence and 95% CI of NHA were estimated using the Aalen-Johansen estimator, accounting for the competing risk for death. Through multivariate cause-specific Cox regression models, factors associated with NHA were examined.<br /><b>Results</b><br />In total, 5,312 TAVR patients were matched to 26,560 control subjects with a median age of 81 years and 56.1% males. Comorbidity burden was higher for TAVR patients. The 3-year cumulative incidence of NHA was 6.3% (95% CI: 5.5%-7.1%) for TAVR patients compared with 5.8% (95% CI: 5.4%-6.1%) for the general population. For TAVR patients >85 years of age, the cumulative incidence of NHA was 11.6% (95% CI: 9.5%-13.8%), and the risk for death was 23.3% (95% CI: 20.4%-26.2%). Factors associated with NHA were increasing age, frailty, living alone, and atrial fibrillation.<br /><b>Conclusions</b><br />TAVR was not associated with an increased incidence of NHA compared with the general population. Despite the increased incidence of NHA for TAVR patients >85 years of age, approximately 2 in 3 patients were still alive and not admitted to nursing homes 3 years after TAVR.<br /><br />Copyright © 2023 The Authors.

<div><h4>Role of the retrograde Carlino technique for chronic total occlusion percutaneous coronary intervention.</h4><i>Azzalini L, Boudou N, Avran A, Kane J, ... Kearney KE, Carlino M</i><br /><b>Background</b><br />There is scarce data on the outcomes of the Carlino technique for chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We aimed to investigate the indications and outcomes of the Carlino technique as performed in the context of the retrograde approach.<br /><b>Methods</b><br />We pooled CTO PCI cases where a retrograde Carlino technique was performed from high-volume operators at four centers. The Carlino technique was characterized according to its indication (achieving plaque/cap modification, clarifying microcatheter location within the vessel, resolving distal cap ambiguity) and was considered successful when it led to the desired outcome.<br /><b>Results</b><br />A total of 43 patients were included. Occlusion complexity was very high (mean J-CTO score 3.3 ± 0.8). The two most common indications were understanding the anatomy of the occlusion and clarifying gear location (37.2%) and impenetrable distal cap (34.9%). The Carlino technique was successful in 88.4% of cases. Overall technical and procedural success was 86.0%. The most common successful crossing technique was reverse controlled antegrade and retrograde subintimal tracking (70.3%). No complications were attributed to the Carlino technique.<br /><b>Conclusions</b><br />We observed a high success rate of the retrograde Carlino technique, as well as overall technical and procedural success rates. No Carlino technique-related complications were observed. Additional data from larger registries are warranted to further confirm the safety and efficacy of this technique.<br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 22 Jan 2023; epub ahead of print</small></div>

<div><h4>Left atrial appendage closure in end-stage renal disease and hemodialysis: Data from a German multicenter registry.</h4><i>Fink T, Paitazoglou C, Bergmann MW, Sano M, ... Sandri M, Eitel I</i><br /><b>Background</b><br />Left atrial appendage closure (LAAC) has emerged as an alternative to oral anticoagulation (OAC) for stroke prevention in patients with atrial fibrillation (AF). OAC treatment has been proven feasible in mild-to-moderate chronic kidney disease (CKD). In contrast, the optimal antithrombotic management of AF patients with end-stage renal disease (ESRD) is unknown and LAAC has not been proven in these patients in prospective randomized clinical trials.<br /><b>Objectives</b><br />The objective of this study is to evaluate safety and efficacy of LAAC in patients with ESRD.<br /><b>Methods</b><br />Patients undergoing LAAC were collected in a German multicenter real-world observational registry. A composite endpoint consisting of the occurrence of ischemic stroke/transient ischemic attack, systemic embolism, and/or major clinical bleeding was assessed. Patients with ESRD were compared with propensity score-matched patients without severe CKD. ESRD was defined as a glomerular filtration rate < 15 ml/min/1.73 m<sup>2</sup> or chronic hemodialysis treatment.<br /><b>Results</b><br />A total of 604 patients were analyzed, including 57 with ESRD and 57 propensity-matched patients.

Abstract
<div><h4>Percutaneous coronary intervention with drug-coated balloon-only strategy combined with single antiplatelet treatment in patients at high bleeding risk: Single center experience of a novel concept.</h4><i>Räsänen A, Kärkkäinen JM, Eranti A, Eränen J, Rissanen TT</i><br /><b>Objectives</b><br />At least 1 month of dual antiplatelet therapy is required after coronary stenting. The aim of this all-comers retrospective registry study was to assess the efficacy and safety of percutaneous coronary intervention (PCI) using drug-coated balloon (DCB) with single antiplatelet treatment (SAPT).<br /><b>Methods</b><br />Between 2011 and 2020, 232 PCIs were performed in 172 patients using the DCB-only strategy and discharged with SAPT.<br /><b>Results</b><br />The mean age of the patients was 75 ± 11 years and 59% were male. The clinical presentation was stable coronary artery disease (CAD) in 42% of the patients and acute coronary syndrome (ACS) in 58%. The lesions were mainly de novo (96%). The majority (58%) of treated lesions were in large coronary arteries (≥3.0 mm). Most (87%) of the patients were at high bleeding risk (HBR) with at least one major or two minor Academic Research Consortium (ARC) risk factors for bleeding. Periprocedural DAPT was used in 49% of the patients. The 12-month major adverse cardiac events (MACE, the composition of cardiovascular death, nonfatal myocardial infarction, and target-lesion revascularization) rate was 1.4% in stable CAD and 7.1% in ACS. The 12-month all-cause mortality after DBC only + SAPT strategy was 4.1% in stable CAD and 12.1% in ACS. The rate of ischemia-driven target lesion revascularisation (TLR) was 0% in stable CAD and 3.0% in ACS at 12 months. The 12-month rate of significant bleeding (BARC type 2-5) was 10.5%. There were no acute or subacute vessel closures.<br /><b>Conclusions</b><br />Despite the aged patient population with comorbidities, the TLR, MACE, and bleeding rates were low with DCB-only PCI combined with SAPT. This novel approach could reduce the post-PCI bleeding risk in patients with CAD and HBR compared to stenting.<br /><br />© 2023 The Authors.

Abstract
<div><h4>Sex-specific aortic valve calcifications in patients undergoing transcatheter aortic valve implantation.</h4><i>Hokken TW, Veulemans V, Adrichem R, Ooms JF, ... Zeus T, Van Mieghem NM</i><br /><b>Aims</b><br />To study sex-specific differences in the amount and distribution of aortic valve calcification (AVC) and to correlate the AVC load with paravalvular leakage (PVL) post-transcatheter aortic valve intervention (TAVI).<br /><b>Methods and results</b><br />This registry included 1801 patients undergoing TAVI with a Sapien3 or Evolut valve in two tertiary care institutions. Exclusion criteria encompassed prior aortic valve replacement, suboptimal multidetector computed tomography (MDCT) quality, and suboptimal transthoracic echocardiography images. Calcium content and distribution were derived from MDCT. In this study, the median age was 81.7 (25th-75th percentile 77.5-85.3) and 54% male. Men, compared to women, were significantly younger [81.2 (25th-75th percentile 76.5-84.5) vs. 82.4 (78.2-85.9), P ≤ 0.01] and had a larger annulus area [512 mm2 (25th-75th percentile 463-570) vs. 405 mm2 (365-454), P < 0.01] and higher Agatston score [2567 (25th-75th percentile 1657-3913) vs. 1615 (25th-75th percentile 905-2484), P < 0.01]. In total, 1104 patients (61%) had none-trace PVL, 648 (36%) mild PVL, and 49 (3%) moderate PVL post-TAVI. There was no difference in the occurrence of moderate PVL between men and women (3% vs. 3%, P = 0.63). Cut-off values for the Agatston score as predictor for moderate PVL based on the receiver-operating characteristic curve were 4070 (sensitivity 0.73, specificity 0.79) for men and 2341 (sensitivity 0.74, specificity 0.73) for women.<br /><b>Conclusion</b><br />AVC is a strong predictor for moderate PVL post-TAVI. Although the AVC load in men is higher compared to women, there is no difference in the incidence of moderate PVL. Sex-specific Agatston score cut-offs to predict moderate PVL were almost double as high in men vs. women.<br /><br />© The Author(s) 2023.

<div><h4>Prediction of conduction disturbances in patients undergoing transcatheter aortic valve replacement.</h4><i>Pavlicek V, Mahfoud F, Bubel K, Fries P, ... Scheller B, Ukena C</i><br /><b>Aim</b><br />Transcatheter aortic valve replacement (TAVR) can cause intraventricular conduction disturbances (ICA), particularly left bundle branch block (BBB) and high-degree atrioventricular block (HAVB). The aim of this study was to investigate clinical, anatomical, procedural, and electrophysiological parameters predicting ICA after TAVR.<br /><b>Methods</b><br />Patients with severe aortic stenosis (n = 203) without pacing devices undergoing TAVR with a self-expanding (n = 103) or balloon-expanding (n = 100) valve were enrolled. Clinical and anatomical parameters, such as length of the membranous septum (MS) and implantation depth, were assessed. His-ventricular interval (HVi) before and after implantation was determined. 12-lead-electrocardiograms (ECG) before, during and after 3 and 30 days after TAVR were analyzed for detection of any ICA.<br /><b>Results</b><br />Among 203 consecutive patients (aortic valve area 0.78 ± 0.18 cm<sup>2</sup>, age 80 ± 6 years, 54% male, left ventricular ejection fraction 52 ± 10%), TAVR led to a significant prolongation of infranodal conduction in all patients from 49 ± 10 ms to 59 ± 16 ms (p = 0.01). The HVi prolongation was independent of valve types, occurrence of HAVB or ICA. Fifteen patients (7%) developed HAVB requiring permanent pacemaker (PPM) implantation and 63 patients (31%) developed ICA within 30 days. Pre-existing BBB (OR 11.64; 95% CI 2.87-47.20; p = 0.001), new-onset left BBB (OR 15.72; 95% CI 3.05-81.03; p = 0.001), and diabetes mellitus (OR 3.88; 95% CI 1.30-15.99; p = 0.02) independently predicted HAVB requiring PPM. Neither pre-existing right BBB, a prolonged postHVi, increases in PR duration, any of the TAVR implantation procedural and anatomic nor echocardiographic characteristics were predictive for later HAVB.<br /><b>Conclusions</b><br />New-onset left BBB and diabetes mellitus independently predicted HAVB requiring PPM after TAVR and helped to identify patients at risk. Electrophysiologic study (EPS) of atrioventricular conduction was neither specific nor predictive of HAVB and can be skipped.<br /><b>Trial registration number</b><br />NCT04128384 ( https://www.<br /><b>Clinicaltrials</b><br />gov ).<br /><br />© 2023.

<div><h4>Comparison of vessel fractional flow reserve with invasive resting full-cycle ratio in patients with intermediate coronary lesions.</h4><i>Lake P, Halbach M, Kardasch M, Mauri V, ... Adam M, Wienemann H</i><br /><b>Background</b><br />Vessel fractional flow reserve (vFFR) is a novel angiography-derived index for the assessment of myocardial ischemia without the need for pressure wires and hyperemic agents. vFFR has demonstrated very good diagnostic performance compared with the hyperemic index fractional flow reserve (FFR). The aim of this study was to compare vFFR to the non-hyperemic pressure ratio resting full-cycle ratio (RFR).<br /><b>Methods</b><br />This was a retrospective, observational, single-center study of an all-comer cohort undergoing RFR assessment. Invasive coronary angiography was obtained without a dedicated vFFR acquisition protocol, and vFFR calculation was attempted in all vessels interrogated by RFR (1483 lesions of 1030 patients).<br /><b>Results</b><br />vFFR could be analyzed in 986 lesions from 705 patients. Median diameter stenosis was 37% (interquartile range (IQR): 30.0-44.0%), vFFR 0.86 (IQR: 0.81-0.91) and RFR 0.94 (IQR: (0.90-0.97). The correlation between vFFR and RFR was strong (r = 0.70, 95% confidence interval (CI): 0.66-0.74, p < 0.001). Using RFR ≤0.89 as reference, the sensitivity, specificity, positive predictive value, negative predictive value, and overall diagnostic accuracy for vFFR were 77%, 93%, 77%, and 92% and 89%. vFFR yielded a high area under the curve (AUC) of 0.92 (95% CI: 0.90-0.94). The good diagnostic performance of vFFR was confirmed among subgroups of patients with diabetes, severe aortic stenosis, female gender and lesions located in the left anterior descending.<br /><b>Conclusion</b><br />vFFR has a high diagnostic performance taking RFR as the reference standard for evaluating the functional significance of coronary stenoses.<br /><br />Copyright © 2023.

<div><h4>Serum lipoprotein(a) and bioprosthetic aortic valve degeneration.</h4><i>Botezatu SB, Tzolos E, Kaiser Y, Cartlidge TRG, ... Zheng KH, Dweck MR</i><br /><b>Aims</b><br />Bioprosthetic aortic valve degeneration demonstrates pathological similarities to aortic stenosis. Lipoprotein(a) [Lp(a)] is a well-recognized risk factor for incident aortic stenosis and disease progression. The aim of this study is to investigate whether serum Lp(a) concentrations are associated with bioprosthetic aortic valve degeneration.<br /><b>Methods and results</b><br />In a post hoc analysis of a prospective multimodality imaging study (NCT02304276), serum Lp(a) concentrations, echocardiography, contrast-enhanced computed tomography (CT) angiography, and 18F-sodium fluoride (18F-NaF) positron emission tomography (PET) were assessed in patients with bioprosthetic aortic valves. Patients were also followed up for 2 years with serial echocardiography. Serum Lp(a) concentrations [median 19.9 (8.4-76.4) mg/dL] were available in 97 participants (mean age 75 ± 7 years, 54% men). There were no baseline differences across the tertiles of serum Lp(a) concentrations for disease severity assessed by echocardiography [median peak aortic valve velocity: highest tertile 2.5 (2.3-2.9) m/s vs. lower tertiles 2.7 (2.4-3.0) m/s, P = 0.204], or valve degeneration on CT angiography (highest tertile n = 8 vs. lower tertiles n = 12, P = 0.552) and 18F-NaF PET (median tissue-to-background ratio: highest tertile 1.13 (1.05-1.41) vs. lower tertiles 1.17 (1.06-1.53), P = 0.889]. After 2 years of follow-up, there were no differences in annualized change in bioprosthetic hemodynamic progression [change in peak aortic valve velocity: highest tertile [0.0 (-0.1-0.2) m/s/year vs. lower tertiles 0.1 (0.0-0.2) m/s/year, P = 0.528] or the development of structural valve degeneration.<br /><b>Conclusion</b><br />Serum lipoprotein(a) concentrations do not appear to be a major determinant or mediator of bioprosthetic aortic valve degeneration.<br /><br />© The Author(s) 2023.

<div><h4>Trends in Intra-Aortic Balloon Pump Use in Cardiogenic Shock After the SHOCK-II Trial.</h4><i>Nan Tie E, Dinh D, Chan W, Clark DJ, ... Duffy SJ, Melbourne Interventional Group Investigators</i><br /><AbstractText>Myocardial infarction complicated by cardiogenic shock (MI-CS) has a poor prognosis, even with early revascularization. Previously, intra-aortic balloon pump (IABP) use was thought to improve outcomes, but the IABP-SHOCK-II (Intra-aortic Balloon Pump in Cardiogenic Shock-II study) trial found no survival benefit. We aimed to determine the trends in IABP use in patients who underwent percutaneous intervention over time. Data were taken from patients in the Melbourne Interventional Group registry (2005 to 2018) with MI-CS who underwent percutaneous intervention. The primary outcome was the trend in IABP use over time. The secondary outcomes included 30-day mortality and major adverse cardiovascular and cerebrovascular events (MACCEs). Of the 1,110 patients with MI-CS, IABP was used in 478 patients (43%). IABP was used more in patients with left main/left anterior descending culprit lesions (62% vs 46%), lower ejection fraction (<35%; 18% vs 11%), and preprocedural inotrope use (81% vs 73%, all p <0.05). IABP use was associated with higher bleeding (18% vs 13%) and 30-day MACCE (58% vs 51%, both p <0.05). The rate of MI-CS per year increased over time; however, after 2012, there was a decrease in IABP use (p <0.001). IABP use was a predictor of 30-day MACCE (odds ratio 1.6, 95% confidence interval 1.18 to 2.29, p = 0.003). However, IABP was not associated with in-hospital, 30-day, or long-term mortality (45% vs 47%, p = 0.44; 46% vs 50%, p = 0.25; 60% vs 62%, p = 0.39). In conclusion, IABP was not associated with reduced short- or long-term mortality and was associated with increased short-term adverse events. IABP use is decreasing but is predominately used in sicker patients with greater myocardium at risk.</AbstractText><br /><br />Copyright © 2022 Elsevier Inc.

Sicouri S, Ramlawi B</i><br /><b>Background</b><br />Permanent pacemaker implantation (PPI) is a common complication after transcatheter aortic valve implantation (TAVI). The cusp-overlap view (COV) was adopted to reduce PPI risk after TAVI with self-expandable valves (SEVs); however, the evidence remains scarce. We performed a systematic review with meta-analysis comparing COV and the standard coplanar view (CPV) technique to evaluate their effectiveness and safety.<br /><b>Methods</b><br />Following the PRISMA statement, data were extracted from studies published by August 2022 and found in PubMed/MEDLINE, EMBASE, CENTRAL/CCTR, ClinicalTrials.gov, SciELO, LILACS, and Google Scholar. The primary outcome of interest was post-procedural PPI and the secondary outcomes were new left bundle branch block (LBBB), moderate/severe paravalvular leak (PVL), valve dislocation (pop-out); need of second transcatheter heart valve, 30-day mortality, stroke, conversion to surgery, coronary obstruction, implantation depth (mm), and post-TAVI mean gradients (mmHg).<br /><b>Results</b><br />Eleven studies met our eligibility criteria and included 1464 patients in the COV group and 1743 patients in the CPV group. Patients who underwent TAVI with COV had lower risk of PPI (odds ratio 0.48; 95% confidence interval [CI] 0.33-0.70; p = 0.001) and higher implantation depths with COV (mean difference -0.83; 95% CI -1.2 to -0.45; p < 0.001). We did not observe any statistically significant differences in the rates of new LBBB, moderate/severe PVL, valve dislocation, need of second transcatheter heart valve, 30-day mortality, stroke, conversion to surgery, coronary obstruction, and post-TAVI mean gradients (mmHg).<br /><b>Conclusion</b><br />In TAVI with SEVs, the application of COV is associated with lower risk of PPI compared with the standard CPV without increasing risk for adverse outcomes.<br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 19 Jan 2023; epub ahead of print</small></div>

Frerker C, Schmidt T</i><br /><b>Background</b><br />The need for permanent pacemaker (PPM) implantation is a common complication after transcatheter aortic valve replacement (TAVR). Deep implantation position is a risk factor for PPM implantation. Thus, in the field of self-expandable (SE) transcatheter heart valves (THV) cusp overlap projection (COP) technique was implemented to reduce parallax, allowing a more precise guidance of implantation depth.<br /><b>Aims</b><br />This meta-analysis aims to report the outcome of patients undergoing TAVR with SE THV using COP versus conventional implantation technique (CIT).<br /><b>Methods</b><br />Systematical search in MEDLINE and EMBASE yielded five observational controlled studies comparing both implantation techniques for the SE Evolut prosthesis (Medtronic Intern. Ltd., CA, USA) and fulfilling the inclusion criteria for meta-analysis.<br /><b>Results</b><br />Totally, 1227 patients were included, comprising 641 who underwent COP and 586 CIT TAVR. Incidence of post-procedural need for PPM implantation was significantly lower in COP group (9.8% vs 20.6%; OR = 0.43; p < 0.00001). This was accompanied by significantly higher implantation position in COP group (mean difference distance from distal end of the intraventricular portion of the THV to the non-coronary cusp (NCC): - 1.03 mm; p = 0.00001). Incidence of new-onset left bundle branch block did not differ. Regarding procedural and 30-day mortality, technical success, post-procedural aortic regurgitation, and rates of multiple device implantation, no difference between COP and CIT was found.<br /><b>Conclusion</b><br />COP is an effective and safe implantation technique to reduce the need for a permanent pacemaker implantation during TAVR with SE Evolut prosthesis.<br /><br />© 2023.

<div><h4>Prognostic impact and diagnostic value of invasively derived hemodynamic measures in patients with severe aortic stenosis undergoing TAVI.</h4><i>Grundmann D, Goßling A, Schmidt L, Voigtlaender L, ... Seiffert M, Schofer N</i><br /><b>Background</b><br />Ejection time (ET), acceleration time (AT) and time between left ventricular and aortic systolic pressure peaks (T-LVAo) might be of diagnostic and prognostic use in patients with aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI).<br /><b>Aim</b><br />We aimed to assess the diagnostic value and prognostic impact of invasively measured ET, AT, and T-LVAo in patients undergoing TAVI.<br /><b>Methods</b><br />A total of 1274 patients received invasive measurement of ET, AT and T-LVAo prior to TAVI. Anatomic AS severity was assessed by CT-derived aortic valve calcification density (AVC<sub>d</sub>). Impact on all-cause mortality was retrospectively analyzed.<br /><b>Results</b><br />In multivariable linear regression, T-LVAo showed the strongest correlation with AVC<sub>d</sub>. No prognostic impact of T-LVAo was found according to uni- and multivariable analyses. In contrast, using an individual C-statistic derived cutoff (C<sub>D</sub>), patients with ET or AT ≥ C<sub>D</sub> showed lower mortality rates compared to patients with ET or AT < C<sub>D</sub> (1-year mortality: ET ≥ vs. < C<sub>D</sub>: 15.01vs. 33.1%, AT ≥ vs < C<sub>D</sub> 16.3 vs. 26.5%, p < 0.001). Moreover, multivariable analysis identified ET ≥ C<sub>D</sub> (HR 0.61 [95% CI 0.43-0.87; p < 0.007]) to be associated with beneficial outcome after TAVI, independent from clinical risk factors and echocardiography-derived parameters.<br /><b>Conclusion</b><br />Among the studied hemodynamic parameters T-LVAo provides the highest diagnostic value, whereas ET is an outcome predictor beyond clinical risk factors and echocardiographic parameters in AS patients following TAVI. These parameters could be of considerable use in diagnostic evaluation and risk assessment of patients scheduled for TAVI.

<div><h4>Ticagrelor or prasugrel versus clopidogrel in patients undergoing percutaneous coronary intervention for chronic coronary syndromes.</h4><i>Koshy AN, Giustino G, Sartori S, Hooda A, ... Mehran R, Sharma SK</i><br /><b>Background</b><br />Potent P2Y<sub>12</sub> inhibitors such as ticagrelor and prasugrel are superior to clopidogrel in acute coronary syndrome (ACS) patients treated with percutaneous coronary intervention (PCI). Whether this benefit extends to a patient population with chronic coronary syndromes (CCS) is unclear.<br /><b>Aims</b><br />We sought to compare the safety and efficacy of prasugrel and ticagrelor versus clopidogrel in patients undergoing PCI for CCS.<br /><b>Methods</b><br />Consecutive patients undergoing PCI for CCS at a tertiary centre between 2014 and 2019 who were discharged on prasugrel or ticagrelor were compared with those on clopidogrel. The primary endpoint was the composite of death and myocardial infarction (MI), with secondary outcomes including rates of bleeding, stroke, and target vessel revascularisation at 1 year.<br /><b>Results</b><br />Overall, 11,508 patients were included in the study (ticagrelor/prasugrel n=2,860 [24.9%], clopidogrel n=8,648 [75.1%]) with an increasing frequency of potent P2Y<sub>12</sub> inhibitor use over the study period (p<sub>trend</sub><0.001). Clopidogrel was used more frequently in patients with multimorbid risk factors, whereas anatomical or procedural complexity was associated with ticagrelor/prasugrel use (left main PCI, bifurcation PCI, number of lesions, rotational atherectomy). No difference in the incidence of death or MI was noted across the groups (ticagrelor/prasugrel vs clopidogrel: 2.7% vs 3.1%, adjusted hazard ratio [adjHR] 0.86, 95% confidence interval [CI]: 0.62-1.17; p=0.33) or secondary outcomes including bleeding (adjHR 0.75, 95% CI: 0.46-1.21; p=0.23) on propensity score stratification analysis. Additionally, no difference in the primary outcome was observed across subgroups, including those undergoing complex PCI.<br /><b>Conclusions</b><br />Ticagrelor and prasugrel are increasingly used in patients with CCS undergoing PCI with similar 1-year efficacy and safety when compared to clopidogrel. Whether use of these agents can be beneficial in patients undergoing PCI for CCS with a high thrombotic and low bleeding risk warrants further study.<br /><br /><br /><br /><small>EuroIntervention: 19 Jan 2023; epub ahead of print</small></div>

<div><h4>Association with carotid plaque parameters detected on contrast-enhanced ultrasound and coronary artery plaque progression in non-culprit lesions: A retrospective study.</h4><i>Ren L, Han Y, Long M, Yan L, ... Fei X, Luo Y</i><br /><b>Aim</b><br />To investigate the correlation between carotid plaque parameters detected on contrast-enhanced ultrasound(CEUS) and the plaque progression in non-culprit coronary lesions (NCCLs) after percutaneous coronary intervention (PCI).<br /><b>Methods</b><br />In this retrospective cross-sectional study, we analyzed 173 patients who underwent PCI. Patients were stratified into two groups (progression and non-progression groups) by comparing the coronary angiography (CAG) results at baseline and follow-up. The correlation between carotid plaque parameters and plaque progression in NCCLs was analyzed by multivariate logistic regression analysis. A logistic regression model was established to predict NCCLs progression.<br /><b>Results</b><br />Overall, 55 of 173 patients exhibited NCCLs progression (31.79%). Univariate comparisons showed that plaque thickness, plaque length, and IPN score were significantly higher in the progressive group than in the non-progressive group (P < 0.01). Multivariate logistic regression analysis revealed that carotid plaque length (OR = 3.418, 95% CI =1.101-10.610) and IPN score (OR = 7.395, 95% CI =3.154-17.342) were strongly associated with plaque progression in NCCLs. After adjusting for confounders, the history of previous PCI, plaque length, and IPN score were independent predictors of the NCCLs progression (P < 0.05). The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of the logistic regression model in predicting the NCCLs progression were 62.50%, 90.53%, 81.12%, 76.92%, and 82.69%, respectively, and the area under the receiver operating characteristic (ROC) curve was 0.882 (95% CI: 0.826-0.939).<br /><b>Conclusions</b><br />Carotid plaque length and IPN score were strongly correlated with plaque progression in NCCLs. Combining the history of previous PCI can reasonably predict the NCCLs progression.<br /><br />Copyright © 2023.

Abstract
<div><h4>Long-term follow-up of contemporary drug-eluting stent implantation in diabetic patients: Subanalysis of a randomized controlled trial.</h4><i>van Hemert ND, Voskuil M, Rozemeijer R, Kraaijeveld AO, ... Stella PR, ReCre8 Study Investigators</i><br /><b>Objective</b><br />The elevated risk of adverse events following percutaneous coronary intervention in diabetic patients persists with newer-generation DES. The polymer-free amphilimus-eluting stent (PF-AES) possesses characteristics with a potentially enhanced performance in patients with diabetes. Data from the 1-year follow-up period has been previously published. The aim of this subanalysis was to assess long-term performance of two contemporary drug-eluting stents (DES) in a diabetic population.<br /><b>Methods</b><br />In the ReCre8 trial, patients were stratified for diabetes and troponin status, and randomized to implantation of a permanent polymer zotarolimus-eluting stent (PP-ZES) or PF-AES. The primary endpoint was target-lesion failure (TLF), a composite of cardiac death, target-vessel myocardial infarction and target-lesion revascularization. Clinical outcomes between discharge and 3 years follow-up were assessed.<br /><b>Results</b><br />A total of 302 patients with diabetes were included in this analysis. After 3 years, TLF occurred in 12.5% of PP-ZES patients versus 10.0% in PF-AES patients (p = 0.46). Similarly, the separate components of TLF were comparable between the two study arms. The secondary composite endpoint of NACE was higher in the PP-ZES arm with 45 cases (29.6%) versus 30 cases (20.0%) in the PF-AES arm (p = 0.036). In the insulin-dependent diabetic population, TLF occurred in 19.1% of PP-ZES patients versus 10.4% of PF-AES patients (p = 0.21). NACE occurred in 40.4% of PP-ZES patients versus 27.1% of PF-AES patients (p = 0.10).<br /><b>Conclusions</b><br />This subanalysis shows that the use of PF-AES results in similar clinical outcomes as compared to PP-ZES, yet some benefits of use of PF-AES in diabetic patients may prevail. Future dedicated trials should confirm these findings.<br /><br />© 2023 The Authors.

<div><h4>Comparison of Echocardiographic and Catheter Mean Gradient to Assess Stenosis After Transcatheter Aortic Valve Implantation.</h4><i>DeSa TB, Tecson KM, Lander SR, Stoler RC, ... Henry AC, Grayburn PA</i><br /><AbstractText>Discordance exists between Doppler-derived and left heart catheterization (LHC)-derived mean gradient (MG) in transcatheter aortic valve implantation (TAVI). We compared echocardiographic parameters of prosthetic valve stenosis and LHC-derived MG in new TAVIs. In a retrospective, single-center study, intraoperative transesophageal echocardiogram (TEE)-derived MG, LHC-derived MG, and acceleration time (AT) were obtained before and after TAVI in 362 patients. Discharge MG, AT, and Doppler velocity index (DVI) using transthoracic echocardiogram (TTE) were also obtained. MG ≥10 mm Hg was defined as abnormal. During native valve assessment with pre-TAVI TEE and pre-TAVI LHC, Pearson correlation coefficient revealed a nearly perfect linear relation between both methods\' MGs (r = 0.97, p <0.0001). Intraoperatively, after TAVI, Spearman correlation coefficient revealed a weak-to-moderate relation between post-TAVI TEE and LHC MGs (r = 0.33, p <0.0001). Significant differences were observed in categorizations between post-TAVI TEE MG and post-TAVI AT (McNemar test p = 0.0003) and between post-TAVI TEE MG and post-TAVI LHC MG (signed-rank test p <0.0001), with TEE MG more likely to misclassify a patient as abnormal. At discharge, 30% of patients had abnormal TTE MG, whereas 0% and 0.8% of patients had abnormal DVI and AT, respectively. Discharge TTE MG was not associated with death or hospitalization for heart failure at a median follow-up of 862 days. Post-TAVI Doppler-derived MG by intraoperative TEE was higher than LHC, despite being virtually identical before implantation. At discharge, patients were more likely to be classified as abnormal using MG than DVI and AT. Elevated MG at discharge was not associated with death or hospitalization for heart failure.</AbstractText><br /><br />Copyright © 2022 Elsevier Inc.

<div><h4>Serial Magnetic Resonance Imaging for Aortic Dilation in Tetralogy of Fallot With Pulmonary Stenosis.</h4><i>Lyon SM, Ofner S, Cheng P, Powell S, ... Herrmann JL, Patel JK</i><br /><AbstractText>Aortic dilation occurs in patients with repaired tetralogy of Fallot (TOF), but the rate of growth is incompletely characterized. The aim of this study was to assess the rates of growth of the aortic root and ascending aorta in a cohort of pediatric and adult patients with sequential magnetic resonance angiography Magnetic Resonance Imaging (MRI) data. Using serial MRI data from pediatric and adult patients with repaired TOF, we performed a retrospective analysis of the rates of growth and associations with growth of the aortic root and ascending aorta. Patients with pulmonary atresia or absent pulmonary valve were excluded. Between years 2005 to 2021, a total of 99 patients were enrolled. A follow-up MRI was performed an average of 5.9 ± 3.7 years from the initial study. For the cohort aged ≥16 years, the mean rate of change in diameter was 0.2 ± 0.5 mm/year at the ascending aorta and 0.2 ± 0.6 mm/year at the sinus of Valsalva. For the entire cohort, the mean change in cross-sectional area indexed to height at the ascending aorta was 7 ± 12 mm<sup>2</sup>/m/year and at the sinus of Valsalva was 10 ± 16 mm<sup>2</sup>/m/year. Younger age was associated with higher rates of growth of the sinus of Valsalva while the use of β blockers or angiotensin-converting enzyme inhibitors was associated with a slower rate of growth. There were no cases of aortic dissection in this cohort. We conclude that serial MRI demonstrates a slow rate of growth of the aorta in the TOF.</AbstractText><br /><br />Copyright © 2022 Elsevier Inc.

<div><h4>Dual or single antiplatelet therapy after coronary surgery for acute coronary syndrome (TACSI trial): Rationale and design of an investigator-initiated, prospective, multinational, registry-based randomized clinical trial.</h4><i>Malm CJ, Alfredsson J, Erlinge D, Gudbjartsson T, ... Tønnessen T, Jeppsson A</i><br /><AbstractText>The TACSI trial (ClinicalTrials.gov Identifier: NCT03560310) tests the hypothesis that one-year treatment with dual antiplatelet therapy (DAPT) with acetylsalicylic acid (ASA) and ticagrelor is superior to only ASA after isolated coronary artery bypass grafting (CABG) in patients with acute coronary syndrome. The TACSI trial is an investor-initiated pragmatic, prospective, multinational, multicenter, open-label, registry-based randomized trial with 1:1 randomization to DAPT with ASA and ticagrelor or ASA only, in patients undergoing first isolated CABG, with a planned enrollment of 2200 patients at Nordic cardiac surgery centers. The primary efficacy endpoint is a composite of time to all cause death, myocardial infarction, stroke, or new coronary revascularization within 12 months after randomization. The primary safety endpoint is time to hospitalization due to major bleeding. Secondary efficacy endpoints include time to the individual components of the primary endpoint, cardiovascular death and rehospitalization due to cardiovascular causes. High-quality health-care registries are used to assess primary and secondary endpoints. The patients will be followed for 10 years. The TACSI trial will give important information useful for guiding the antiplatelet strategy in acute coronary syndrome patients treated with CABG.</AbstractText><br /><br />Copyright © 2023.

<div><h4>Cardiac computed tomography based analysis of mitral annulus, coronary sinus and left circumflex artery in patients with mitral regurgitation: Implications for transcatheter mitral annuloplasty techniques.</h4><i>Lin F, Wang Q, Meng L, Liang Y, ... Zhang Q, Gu X</i><br /><b>Introduction</b><br />CT imaging analysis of mitral annulus (MA), coronary sinus (CS) and left circumflex artery (LCX) is critical to transcatheter mitral annuloplasty (TMA), which, however, is scantly reported. We aimed to comprehensively assess MA, CS and LCX anatomy and geometry in mitral regurgitation (MR) based on 3-D reconstruction of cardiac CT images.<br /><b>Methods</b><br />Patients with primary or secondary MR and patients without MR were recruited and underwent cardiac CT examination. MR severity was evaluated by echocardiography. 3-D reconstruction of cardiac CT images was done by the Mimics Research 21.0 software. A MA-centered two dimensional coordinate system, a CS plane, a MA plane and a series of auxiliary planes along the posterior MA were created for the measurement of parameters defining MA, CS and LCX anatomy and geometry during the cardiac cycle.<br /><b>Results</b><br />The secondary MR group had a significantly higher MA perimeter index than the other two groups during the cardiac cycle. The CS diameters at most sites, and the posterior MA radian were substantially greater in the two MR groups. Distances between the CS and MA at some locations were significant different among the three groups. The secondary MR group had a significantly smaller CS-MA plane angle than the other two groups during systole, and than control group during diastole. The site where the CS crossed LCX was pinpointed.<br /><b>Conclusion</b><br />The comprehensive information from this study may help improve the results of TMA and enhance the design of devices for a better annuloplasty effect.<br /><br />Copyright © 2023.

<div><h4>Quantitative flow ratio versus fractional flow reserve for guiding percutaneous coronary intervention: design and rationale of the randomised FAVOR III Europe Japan trial.</h4><i>Andersen BK, Sejr-Hansen M, Westra J, Campo G, ... Christiansen EH, Holm NR</i><br /><AbstractText>Quantitative flow ratio (QFR) is a computation of fractional flow reserve (FFR) based on invasive coronary angiographic images. Calculating QFR is less invasive than measuring FFR and may be associated with lower costs. Current evidence supports the call for an adequately powered randomised comparison of QFR and FFR for the evaluation of intermediate coronary stenosis. The aim of the FAVOR III Europe Japan trial is to investigate if a QFR-based diagnostic strategy yields a non-inferior 12-month clinical outcome compared with a standard FFR-guided strategy in the evaluation of patients with intermediary coronary stenosis. FAVOR III Europe Japan is an investigator-initiated, randomised, clinical outcome, non-inferiority trial scheduled to randomise 2,000 patients with either 1) stable angina pectoris and intermediate coronary stenosis, or 2) indications for functional assessment of at least 1 non-culprit lesion after acute myocardial infarction. Up to 40 international centres will randomise patients to either a QFR-based or a standard FFR-based diagnostic strategy. The primary endpoint of major adverse cardiovascular events is a composite of all-cause mortality, any myocardial infarction, and any unplanned coronary revascularisation at 12 months. QFR could emerge as an adenosine- and wire-free alternative to FFR, making the functional evaluation of intermediary coronary stenosis less invasive and more cost-effective.</AbstractText><br /><br /><br /><br /><small>EuroIntervention: 17 Jan 2023; epub ahead of print</small></div>

<div><h4>Trajectory and correlates of pulmonary congestion by lung ultrasound in patients with acute myocardial infarction: Insights from PARADISE-MI.</h4><i>Platz E, Claggett B, Jering KS, Kovacs A, ... Pfeffer MA, Shah A</i><br /><b>Background</b><br />PARADISE-MI examined the efficacy of sacubitril/valsartan in acute myocardial infarction (AMI) complicated by reduced left ventricular ejection fraction (LVEF), pulmonary congestion or both. We sought to assess the trajectory of pulmonary congestion using lung ultrasound (LUS) and its association with cardiac structure and function in a prespecified substudy.<br /><b>Methods</b><br />Patients without prior heart failure (HF) underwent 8-zone LUS and echocardiography at baseline (±2 days of randomization) and after 8 months. B-lines were quantified offline, blinded to treatment, clinical findings, timepoint and outcomes.<br /><b>Results</b><br />Among 152 patients (median age 65, 32% women, mean LVEF 41%), B-lines were detectable in 87% at baseline (median B-line count: 4 [IQR 2-8]). Among 115 patients with LUS data at baseline and follow-up, B-lines decreased significantly from baseline (mean ± SD: -1.6 ± 7.3; p=0.018). The proportion of patients without pulmonary congestion at follow-up was significantly higher in those with fewer B-lines at baseline. Adjusted for baseline, B-lines at follow-up were on average 6 (95% CI: 3, 9) higher in patients who experienced an intercurrent HF event vs. those who did not (p=0.001). A greater number of B-lines at baseline was associated with larger left atrial size, higher E/e\' and E/A ratios, greater degree of mitral regurgitation, worse right ventricular systolic function, and higher tricuspid regurgitation velocity (p trend <0.05 for all).<br /><b>Conclusions</b><br />In this AMI cohort, B-lines, indicating pulmonary congestion, were common at baseline and, on average, decreased significantly from baseline to follow-up. Worse pulmonary congestion was associated with prognostically important echocardiographic markers.<br /><br />© The Author(s) 2023.

<div><h4>Ticagrelor With or Without Aspirin in High-Risk Patients With Anemia Undergoing Percutaneous Coronary Intervention: a subgroup analysis of the TWILIGHT trial.</h4><i>Spirito A, Kastrati A, Cao D, Baber U, ... Pocock S, Mehran R</i><br /><b>Aim</b><br />The aim of this study was to assess the effect of ticagrelor monotherapy among high-risk patients with anemia undergoing percutaneous coronary intervention (PCI).<br /><b>Methods and results</b><br />In the TWILIGHT trial (Ticagrelor With Aspirin or Alone in High-Risk Patients after Coronary Intervention), after 3 months of ticagrelor plus aspirin, high-risk patients were maintained on ticagrelor and randomized to aspirin or placebo for 1 year. Anemia was defined as hemoglobin <13 g/dL for men and <12 g/dL for women. The primary endpoint was Bleeding Academic Research Consortium (BARC) 2, 3, or 5 bleeding. The key secondary endpoint was a composite of all-cause death, myocardial infarction, or stroke.Out of 6 828 patients, 1 329 (19.5%) had anemia and were more likely to have comorbidities, multivessel disease, and to experience bleeding or ischemic complications than non-anemic patients. Among anemic patients, BARC 2, 3, or 5 bleeding occurred less frequently with ticagrelor monotherapy than with ticagrelor plus aspirin (6.4% vs. 10.7%; HR 0.60; 95% CI 0.41 to 0.88; p = 0.009); the rate of the key secondary endpoint was similar in the two arms (5.2% vs. 4.8%; HR 1.07; 95% CI 0.66 to 1.74; p = 0.779). These effects were consistent in patients without anemia (interaction p-value 0.671 and 0.835, respectively).<br /><b>Conclusions</b><br />In high-risk patients undergoing PCI, ticagrelor monotherapy after 3 months of ticagrelor-based DAPT was associated with a reduced risk of clinically relevant bleeding without any increase in ischemic events irrespective of anemia status.

<div><h4>Matched comparison between external aortic root support and valve-sparing root replacement.</h4><i>Van Hoof L, Lamberigts M, Noé D, El-Hamamsy I, ... Verbrugghe P, Aortic Valve Repair Research Network Investigators from the Heart Valve Society</i><br /><b>Objectives</b><br />Differences in indication and technique make a randomised comparison between valve-sparing root replacement (VSRR) and personalised external aortic root support (PEARS) challenging. We performed a propensity score (PS)-matched comparison of PEARS and VSRR for syndromic root aneurysm.<br /><b>Methods</b><br />Patients in the PEARS 200 Database and Aortic Valve Insufficiency and ascending aorta Aneurysm InternATiOnal Registry (undergoing VSRR) with connective tissue disease operated electively for root aneurysm <60 mm with aortic regurgitation (AR) <1/4 were included. Using a PS analysis, 80 patients in each cohort were matched. Survival, freedom from reintervention and from AR ≥2/4 were estimated using a Kaplan-Meier analysis.<br /><b>Results</b><br />Median follow-up was 25 and 55 months for 159 PEARS and 142 VSRR patients. Seven (4.4%) patients undergoing PEARS required an intervention for coronary injury or impingement, resulting in one death (0.6%). After VSRR, there were no early deaths, 10 (7%) reinterventions for bleeding and 1 coronary intervention. Survival for matched cohorts at 5 years was similar (PEARS 98% vs VSRR 99%, p=0.99). There was no difference in freedom from valve or ascending aortic/arch reintervention between matched groups. Freedom from AR ≥2/4 at 5 years in the matched cohorts was 97% for PEARS vs 92% for VSRR (p=0.55). There were no type A dissections.<br /><b>Conclusions</b><br />VSRR and PEARS offer favourable mid-term survival, freedom from reintervention and preservation of valve function. Both treatments deserve their place in the surgical repertoire, depending on a patient\'s disease stage.

<div><h4>Long-Term Outcomes and Duration of Dual Antiplatelet Therapy After Coronary Intervention With Second-Generation Drug-Eluting Stents: The Veterans Affairs Extended DAPT Study.</h4><i>Kinlay S, Young MM, Sherrod R, Gagnon DR</i><br /><AbstractText><br /><b>Background:</b><br/>Recent guidelines on dual antiplatelet therapy (DAPT) duration after percutaneous coronary intervention (PCI) balance the subsequent risks of major bleeding with ischemic events. Although generally favoring shorter DAPT duration with second-generation drug-eluting stents, the effects on long-term outcomes in the wider population are uncertain. Methods and Results We tracked all patients having PCI with second-generation drug-eluting stents in the Veterans Affairs Healthcare System between 2006 and 2016 for death, myocardial infarction, stroke, and major bleeding up to 13 years. We compared these outcomes with 4 DAPT durations of 1 to 5, 6 to 9, 10 to 12, and 13 to 18 months after the index PCI using hazard ratios (HRs) and 95% CIs from Cox proportional hazards models adjusted by inverse probability weighting. A total of 40 882 subjects with PCI were followed up for a median of 4.3 (25%-75%: 2.4-6.5) years. DAPT discontinuation was rare early after PCI (5.8% at 1-5 months and 6.3% at 6-9 months) but increased (19% and 44%) >9 months. The risk of cardiovascular and noncardiovascular death was higher (HR, 2.03-3.41) with DAPT discontinuation <9 months, likely reflecting premature cessation from factors related to early death. DAPT discontinuation after 9 months following PCI was associated with lower risks of death (HR, 0.93 [95% CI, 0.88-0.99]), cardiac death (HR, 0.79 [95% CI, 0.70-0.90]), myocardial infarction (HR, 0.75 [95% CI, 0.69-0.82]), and major bleeding (HR, 0.82 [95% CI, 0.74-0.91]). Results were similar with an index PCI for an acute coronary syndrome. <br /><b>Conclusions:</b><br/>Stopping DAPT after 9 months is associated with lower long-term risks of adverse ischemic and bleeding events and supports recent guidelines of shorter duration DAPT after PCI with second-generation drug-eluting stents.</AbstractText><br /><br /><br /><br /><small>J Am Heart Assoc: 16 Jan 2023:e027055; epub ahead of print</small></div>

<div><h4>Heart-Brain Team Approach of Acute Myocardial Infarction Complicating Acute Stroke: Characteristics of Guideline-Recommended Coronary Revascularization and Antithrombotic Therapy and Cardiovascular and Bleeding Outcomes.</h4><i>Suzuki T, Kataoka Y, Shiozawa M, Morris K, ... Tsujita K, Noguchi T</i><br /><AbstractText><br /><b>Background:</b><br/>Acute myocardial infarction (AMI) infrequently occurs after acute stroke. The Heart-brain team approach has a potential to appropriately manage this poststroke cardiovascular complication. However, clinical outcomes of AMI complicating acute stroke (AMI-CAS) with the heart-brain team approach have not been characterized. The current study investigated cardiovascular outcomes in patients with AMI-CAS managed by a heart-brain team. Methods and Results We retrospectively analyzed 2390 patients with AMI at our institute (January 1, 2007-September 30, 2020). AMI-CAS was defined as the occurrence of AMI within 14 days after acute stroke. Major adverse cerebral/cardiovascular events (cardiac-cause death, nonfatal myocardial infarction, and nonfatal stroke) and major bleeding events were compared in subjects with  AMI-CAS and those without acute stroke. AMI-CAS was identified in 1.6% of the subjects. Most AMI-CASs (37/39=94.9%) presented ischemic stroke. Median duration of AMI from the onset of acute stroke was 2 days. Patients with AMI-CAS less frequently received primary percutaneous coronary intervention (43.6% versus 84.7%; <i>P</i><0.001) and dual-antiplatelet therapy (38.5% versus 85.7%; <i>P</i><0.001), and 33.3% of them did not receive any antithrombotic agents (versus 1.3%; <i>P</i><0.001). During the observational period (median, 2.4 years [interquartile range, 1.1-4.4 years]), patients with AMI-CAS exhibited a greater likelihood of experiencing major adverse cerebral/cardiovascular events (hazard ratio [HR], 3.47 [95% CI, 1.99-6.05]; <i>P</i><0.001) and major bleeding events (HR, 3.30 [95% CI, 1.34-8.10]; <i>P</i>=0.009). These relationships still existed even after adjusting for clinical characteristics and medication use (major adverse cerebral/cardiovascular event: HR, 1.87 [95% CI, 1.02-3.42]; <i>P</i>=0.04; major bleeding: HR, 2.67 [95% CI, 1.03-6.93]; <i>P</i>=0.04). <br /><b>Conclusions:</b><br/>Under the heart-brain team approach, AMI-CAS was still a challenging disease, reflected by less adoption of primary percutaneous coronary intervention and antithrombotic therapies, with substantially elevated cardiovascular and major bleeding risks. Our findings underscore the need for a further refined approach to mitigate their ischemic/bleeding risks.</AbstractText><br /><br /><br /><br /><small>J Am Heart Assoc: 16 Jan 2023:e8140; epub ahead of print</small></div>

<div><h4>Circulating Progenitor Cells Are Associated With Bioprosthetic Aortic Valve Deterioration: A Preliminary Study.</h4><i>Kanaji Y, Ozcan I, Toya T, Gulati R, ... Lerman LO, Lerman A</i><br /><AbstractText><br /><b>Background:</b><br/>Mechanisms underlying bioprosthetic valve deterioration are multifactorial and incompletely elucidated. Reparative circulating progenitor cells, and conversely calcification-associated osteocalcin expressing circulating progenitor cells, have been linked to native aortic valve deterioration. However, their role in bioprosthetic valve deterioration remains elusive. This study sought to evaluate the contribution of different subpopulations of circulating progenitor cells in bioprosthetic valve deterioration. Methods and Results This single-center prospective study enrolled 121 patients who had peripheral blood mononuclear cells isolated before bioprosthetic aortic valve replacement and had an echocardiographic follow-up ≥2 years after the procedure. Using flow cytometry, fresh peripheral blood mononuclear cells were analyzed for the surface markers CD34, CD133, and osteocalcin. Bioprosthetic valve deterioration was evaluated by hemodynamic valve deterioration (HVD) using echocardiography, which was defined as an elevated mean transprosthetic gradient ≥30 mm Hg or at least moderate intraprosthetic regurgitation. Sixteen patients (13.2%) developed HVD during follow-up for a median of 5.9 years. Patients with HVD showed significantly lower levels of reparative CD34<sup>+</sup>CD133<sup>+</sup> cells and higher levels of osteocalcin-positive cells than those without HVD (CD34<sup>+</sup>CD133<sup>+</sup> cells: 125 [80, 210] versus 270 [130, 420], <i>P</i>=0.002; osteocalcin-positive cells: 3060 [523, 5528] versus 670 [180, 1930], <i>P</i>=0.005 respectively). Decreased level of CD34<sup>+</sup>CD133<sup>+</sup> cells was a significant predictor of HVD (hazard ratio, 0.995 [95% CI, 0.990%-0.999%]). <br /><b>Conclusions:</b><br/>Circulating levels of CD34<sup>+</sup>CD133<sup>+</sup> cells and osteocalcin-positive cells were significantly associated with the subsequent occurrence of HVD in patients undergoing bioprosthetic aortic valve replacement. Circulating progenitor cells might play a vital role in the mechanism, risk stratification, and a potential therapeutic target for patients with bioprosthetic valve deterioration.</AbstractText><br /><br /><br /><br /><small>J Am Heart Assoc: 16 Jan 2023:e027364; epub ahead of print</small></div>

<div><h4>Antithrombotic Therapy and Cardiovascular Outcomes After Transcatheter Aortic Valve Implantation in Patients Without Indications for Chronic Oral Anticoagulation: A systematic review and network meta-analysis of randomized controlled trials.</h4><i>Guedeney P, Roule V, Mesnier J, Chapelle C, ... Montalescot G, Collet JP</i><br /><b>Aims</b><br />As the antithrombotic regimen which may best prevent ischemic complications along with the lowest bleeding risk offset following transcatheter aortic valve implantation (TAVI) remains unclear, we aimed to compare the safety and efficacy of antithrombotic regimens in patients without having an indication for chronic oral anticoagulation.<br /><b>Methods and results</b><br />We conducted a Prospero-registered (CRD42021247924) systematic review and network meta-analysis of randomized controlled trials evaluating post-TAVI antithrombotic regimens up to April 2022. We estimated the relative risk (RR) and 95% confidence intervals (95%CI) using a random-effects model in a frequentist pairwise and network metanalytic approach. We included 7 studies comprising of 4 006 patients with a mean weighted follow-up of 12.9 months. Risk of all-cause death was significantly reduced with dual antiplatelet therapy (DAPT) compared to low-dose rivaroxaban + 3-month single antiplatelet therapy (SAPT) (RR 0.60, 95%CI 0.41-0.88) while no significant reduction was observed with SAPT versus DAPT (RR 1.02 95%CI 0.67-1.58) and SAPT and DAPT compared to apixaban or edoxaban (RR:0.60 95%CI:0.32-1.14 and RR:0.59 95%CI 0.34-1.02, respectively). SAPT was associated with a significant reduction of life-threatening, disabling, or major bleeding compared to DAPT (RR 0.45 95%CI 0.29-0.70), apixaban or edoxaban alone (RR 0.45, 95%CI 0.25-0.79) and low-dose rivaroxaban + 3-month SAPT (RR 0.30, 95%CI 0.16-0.57). There were no differences between the various regimens with respect to myocardial infarction, stroke, or systemic embolism.<br /><b>Conclusion</b><br />Following TAVI in patients without an indication for chronic oral anticoagulant, SAPT more than halved the risk of bleeding compared to DAPT and direct oral anticoagulant-based regimens without significant ischemic offset.<br /><br />© The Author(s) 2023.

<div><h4>Transcatheter aortic valve implantation in patients with anomalous coronary artery.</h4><i>Bajoras V, Diečkus L, Wong I, Laurinavičienė A, Davidavičius G, Čėsna S</i><br /><b>Objectives</b><br />The aim of this review was to analyze literature and provide systematic algorithm to guide decision making during TAVI procedure.<br /><b>Background</b><br />Transcatheter aortic valve implantation (TAVI) is growing in popularity and expanding to younger patients with lower risk profiles. Currently, there is no concise guideline on the management strategy during TAVI in patients with anomalous coronary artery (ACA) anatomy undergoing this procedure.<br /><b>Methods</b><br />A systematic search was conducted for relevant case reports of TAVI in patients who had confirmed ACA anatomy. Twenty-four case reports, that met the criteria for this review, were identified and included in the final study size.<br /><b>Results</b><br />TAVI was successful in 23 out of 24 cases. Half of the cases (12) described performing balloon aortic valvuloplasty (BAV) before TAVI. The majority (15) reported using angiogram Postimplantation. Only one-third of cases (8) reported performing coronary protection (with either wire, wire and stent or wire and balloon). Two-third of case reports (16/24, 67%) mentioned using Edwards SAPIEN balloon expandable transcatheter heart valves (THV).<br /><b>Conclusions</b><br />Preprocedural diagnostic imaging tests play important role in determining the ACA anatomy and its relation to the aortic valve. BAV with simultaneous coronary arteries angiography or aortography should be performed before implantation of THV, as it could potentially predict whether the ACA would be compressed. Using at least a coronary wire for ACA protection is recommended in case there is high risk of ACA obstruction. Management strategy should be individualized when performing TAVI in patients with ACA.<br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 14 Jan 2023; epub ahead of print</small></div>

<div><h4>Effect of randomized prophylactic nitroglycerin on radial artery spasm during transradial catheterization: An analysis based on operator experience.</h4><i>da Silva RL, Dangas GD, de Andrade PB, Joaquim RM, ... Feres F, Costa JR</i><br /><AbstractText>One limitation to transradial access (TRA) is the occurrence of spasms (RAS), for which the use of prophylactic medications is recommended. Improvement in TRA material combined with the increase in operators\' expertise, might mitigate this benefit. We assess the effect of preventive nitroglycerin on RAS during TRA, evaluating the role of the operator\'s experience. Patients received 500 μg nitroglycerin or placebo. The operator\'s expertise was classified as: inexperienced (I), intermediate (M), and experienced (E). 2040 patients were included. Prophylactic use of nitroglycerin did not reduce RAS (10.8% vs. 13.4% (placebo), p = 0.07). RAS incidence was 14.5% in I, 12.5% in M, and 9.7% in E (p = 0.01). In group I, nitroglycerin reduced RAS (17.4% vs. 11.1%, p = 0.04), which was not observed in other groups. Overall, nitroglycerin does not prevent RAS, which is more common among inexperienced operators. More experienced operators could abolish preventive nitroglycerin use.</AbstractText><br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 14 Jan 2023; epub ahead of print</small></div>

<div><h4>A very rare vascular complication of the Edwards expandable eSheath during transcatheter aortic valve replacement.</h4><i>Savvoulidis P, Nadir AM, Mechery A, Doshi SN</i><br /><AbstractText>Transcatheter aortic valve replacement (TAVR) has revolutionized the management of severe symptomatic aortic valve stenosis. TAVR is now indicated as an alternative to surgical replacement in a wide risk profile ranging from high to low surgical risk. Although vascular complications have decreased in frequency over time, with the introduction of lower profile delivery systems and sheaths, they remain one of the most frequently encountered and serious complications of TAVR. Patient-specific predisposing factors have been well characterized. However, much less is known about device-specific complications. Awareness of the possible device-related complications may lead to earlier identification, prompt management, and better outcomes. We report a previously unreported complication of the Edwards expandable eSheath that lead to avulsion of the external iliac artery following successful TAVR with a 29-mm Edwards Sapien 3 transcatheter heart valve. Bleeding was promptly controlled with an occlusion balloon and emergency surgical repair was required with a favorable outcome.</AbstractText><br /><br />© 2023 The Authors.

<div><h4>Timing of sedation and patient-reported pain outcomes during cardiac catheterization: Results from the UNTAP-intervention study.</h4><i>Mall A, Girton TA, Yardley K, Ronn M, ... Jones WS, Granger BB</i><br /><b>Background</b><br />Invasive cardiac catheterization (CC) temporarily increases pain, discomfort, and anxiety. Procedural sedation is deployed to mitigate these symptoms, though practice varies. Research evaluating peri-procedural patient-reported outcomes is lacking.<br /><b>Methods and results</b><br />We randomized 175 patients undergoing CC to short interval ([SI] group, <6 min) or long interval ([LI] group, ≥6 min) time intervals between initial intravenous sedation and local anesthetic administration. Outcomes included: (1) total pain medication use, (2) patient-reported and behaviorally assessed pain and (3) patient satisfaction during outpatient CC. Generalized linear mixed effect models were used to evaluate the impact of treatment time interval on total medication utilization, pain, and satisfaction. Among enrollees the mean age was 62 (standard deviation [SD] = 13.4), a majority were male (66%), white (74%), and overweight (mean body mass index = 28.5 [SD = 5.6]). Total pain medication use did not vary between treatment groups (p = 0.257), with no difference in total fentanyl (p = 0.288) or midazolam (p = 0.292). Post-treatment pain levels and nurse-observed pain were not statistically significant between groups (p = 0.324 & p = 0.656, respectively. No significant differences with satisfaction with sedation were found between the groups (p = 0.95) Patient-reported pain, satisfaction and nurse-observed measures of pain did not differ, after adjustment for demographic and procedural factors. Analyses of treatment effect modification revealed that postprocedure self-reported pain levels varied systematically between individuals undergoing percutaneous coronary intervention (PCI) (SI = 2.2 [0.8, 3.6] vs. LI = 0.7 [-0.6, 2.0]) compared with participants not undergoing PCI (SI = 0.4 [-0.8, 1.7] vs. LI = 0.7 [-0.3, 1.6]) (p = 0.043 for interaction).<br /><b>Conclusion</b><br />No consistent treatment differences were found for total medication dose, pain, or satisfaction regardless of timing between sedation and local anesthetic. Treatment moderations were seen for patients undergoing PCI.

<div><h4>Temporary balloon occlusion test can overestimate the risk of acute pulmonary edema after transcatheter atrial septal defect closure.</h4><i>Nakagawa K, Akagi T, Takaya Y, Miki T, ... Morita H, Ito H</i><br /><b>Background</b><br />Atrial septal defect (ASD) closure can cause acute pulmonary edema. Before transcatheter closure is performed, temporary balloon occlusion test (BOT) is recommended in patients with left ventricular dysfunction to predict the risk of pulmonary edema. However, the accuracy of BOT has not been verified. This study aimed to compare hemodynamic differences between BOT and transcatheter closure.<br /><b>Methods</b><br />A total of 42 patients with a single ASD over age 18 years who underwent BOT before transcatheter ASD closure between October 2010 and May 2020 were analyzed. Pulmonary capillary wedge pressure (PCWP) was measured using a Swan-Ganz catheter placed in the pulmonary artery at baseline, after 10 min of BOT, and after transcatheter closure. Amplatzer septal occluder was used for all transcatheter closures.<br /><b>Results</b><br />Mean patient age was 64 ± 18 years (range, 18-78). Mean ASD diameter and pulmonary to systemic flow ratio were 18 ± 5 and 2.8 ± 1.0 mm, respectively. Mean PCWP at baseline, during BOT, and after transcatheter closure was 8.9 ± 2.9, 13.5 ± 4.2, and 9.5 ± 2.6 mmHg, respectively. The difference between BOT and after transcatheter closure values was significant (p < 0.001). During BOT, PCWP increased ≥18 mmHg in 7 patients, whereas after ASD closure, PCWP was <18 mmHg in all 7 and none developed acute pulmonary edema.<br /><b>Conclusion</b><br />Temporary balloon occlusion of an ASD and transcatheter ASD closure result in different hemodynamic change. BOT overestimates increase of PCWP after transcatheter ASD closure and requires careful interpretation. Well-designed, larger studies in higher-risk patients are warranted to verify the clinical implications of BOT in more detail.<br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 14 Jan 2023; epub ahead of print</small></div>

<div><h4>Coronary Artery Calcium Dispersion and Cause-Specific Mortality.</h4><i>Dudum R, Dardari ZA, Feldman DI, Berman DS, ... Patel J, Blaha MJ</i><br /><AbstractText>Coronary artery calcium (CAC) measures subclinical atherosclerosis and improves risk stratification. CAC characteristics-including vessel(s) involved, number of vessels, volume, and density-have been shown to differentially impact risk. We assessed how dispersion-either the number of calcified vessels or CAC phenotype (diffuse, normal, and concentrated)-impacted cause-specific mortality. The CAC Consortium is a retrospective cohort of 66,636 participants without coronary heart disease (CHD) who underwent CAC scoring. This study included patients with CAC >0 (n = 28,147). CAC area, CAC density, and CAC phenotypes (derived from the index of diffusion = 1 - [CAC in most concentrated vessel/total Agatston score]) were calculated. The associations between CAC characteristics and cause-specific mortality were assessed. The participant details included (n = 28,147): mean age 58.3 years, 25% female, 89.6% White, and 66% had 2+ calcified vessels. Diabetes, hypertension, and hyperlipidemia were predictors of multivessel involvement (p <0.001). After controlling for the overall CAC score, those with 4-vessel CAC involvement had more CAC area and less dense calcifications than those with 1-vessel. There was a graded increase in all-cause and cardiovascular disease (CVD)- and CHD-specific mortality as the number of calcified vessels increased. Among those with ≥2 vessels involved (n = 18,516), a diffuse phenotype was associated with a higher CVD-specific mortality and had a trend toward higher all-cause and CHD-specific mortality than a concentrated CAC phenotype. Diffuse CAC involvement was characterized by less dense calcification, more CAC area, multiple coronary vessel involvement, and presence of certain traditional risk factors. There is a graded increase in all-cause and CVD- and CHD-specific mortality with increasing CAC dispersion.</AbstractText><br /><br />Copyright © 2022 Elsevier Inc.

<div><h4>Immature neutrophil is associated with coronary plaque vulnerability based on optical coherence tomography analysis.</h4><i>Wan M, Lu Y, Mao B, Yu S, ... Li X, Zhuang J</i><br /><b>Introduction</b><br />High neutrophil to lymphocyte ratio is considered to predict poor prognosis of acute coronary syndrome (ACS). However, the association of neutrophil subpopulation with plaque vulnerability and the incidence of ACS remains unknown.<br /><b>Methods and results</b><br />Blood samples from 48 patients with unstable angina (UA), 31 with ST-segment elevation myocardial infarction (STEMI) and 33 healthy controls were collected at admission. The morphology of coronary plaques in 48 UA patients were further evaluated by optical coherence tomography (OCT). According to maturation stages of neutrophils and the expression of CD10 and CD101, circulating neutrophils could be divided into pre-neutrophils (CD101<sup>-</sup>CD10<sup>-</sup>), immature neutrophils (CD101<sup>+</sup>CD10<sup>-</sup>) and mature neutrophils (CD101<sup>+</sup>CD10<sup>+</sup>). While the number of pre-neutrophil was quite low in blood and comparable among three groups, the absolute counts and percentage of CD10<sup>-</sup> immature neutrophils were higher in peripheral bloods of UA and STEMI patients compared with those in healthy controls. The concentration of plasma myeloperoxidase was positively associated with the percentage of CD10<sup>-</sup> immature neutrophils. Furthermore, UA patients with thin-cap fibroatheroma (TCFA) observed by OCT had a higher proportion and larger number of immature neutrophils as compared to those without TCFA. The percentage of immature neutrophils also closely correlated with plaque rupture and the feature of vulnerable plaque, including thinner fibrous cap and larger lipid core, but did not associate with percent lumen stenosis.<br /><b>Conclusion</b><br />Our findings emphasize that the abnormally increased level of CD10<sup>-</sup> immature neutrophils may sever as a promising marker of the incidence of ACS and plaque vulnerability.<br /><br />Copyright © 2023 The Author.

<div><h4>Estimation of adverse events associated with P2Y12 receptor inhibitors stratified by academic research consortium for high bleeding risk criteria in acute coronary syndrome.</h4><i>Fujii T, Endo S, Tsuchiya R, Nagamatsu H, ... Yoshimachi F, Ikari Y</i><br /><b>Background</b><br />The usefulness of the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria in the selection of P2Y12 receptor inhibitors for acute coronary syndrome is unknown. This study investigated whether the selection of antiplatelet agents according to the ARC-HBR criteria could improve clinical outcomes.<br /><b>Methods</b><br />This multicenter retrospective study included 1261 patients with acute coronary syndrome who received dual antiplatelet therapy, namely clopidogrel (75 mg, n = 529) or prasugrel (3.75 mg, n = 732) in addition to aspirin. The primary endpoint was net adverse clinical events (NACE) after hospital admission, including ischemic (death, myocardial infarction, ischemic stroke) and bleeding events (Bleeding Academic Research Consortium 3 or 5). Secondary outcomes were ischemic and bleeding events. For each patient, the observation period was defined as the duration of dual antiplatelet therapy after admission.<br /><b>Results</b><br />During the observation period (average: 313 days), the rate of NACE was lower in the prasugrel group than the clopidogrel group (20.6% vs. 12.6%, respectively, P < 0.01). In patients who satisfied or did not satisfy the ARC-HBR criteria, prasugrel was associated with a 3.7% and 2.1% lower incidence of NACE, respectively, versus clopidogrel. Ischemic and bleeding events were less frequent in the prasugrel group than the clopidogrel group (11.5% vs. 7.9%, respectively, P = 0.03; 10.6% vs. 5.2%, respectively, P < 0.01). The estimated incidence models for NACE suggested that the difference between clopidogrel and prasugrel was greater in patients who satisfied the ARC-HBR criteria than in those who did not.<br /><b>Conclusions</b><br />Prasugrel is preferable to clopidogrel regardless of the ARC-HBR.<br /><br />Copyright © 2023.

Another DREAMS 3G was implanted into one mini swine for crystallinity analysis of the degradation end product after 730 days. Degradation kinetics were determined at 28, 90, 120, 180, and 365 days.<br /><b>Results</b><br />Discontinuity density in DREAMS 3G was significantly lower than that in Magmaris scaffolds for the follow-up timepoints of 90 and 120 days. Planimetric analysis indicated 99.6% backbone degradation for DREAMS 3G at 12 months. Compared to the Magmaris scaffold, individual strut degradation in DREAMS 3G showed less variability and the remaining backbone core was more homogeneous. The degradation end product of DREAMS 3G manifested as calcium phosphate with a minor share of aluminium phosphate.<br /><b>Conclusions</b><br />DREAMS 3G showed almost complete degradation after one year, with amorphous calcium and aluminium phosphate as the end products of degradation. Despite its thinner struts, scaffold discontinuity was significantly lower in the DREAMS 3G than in the Magmaris scaffold, likely providing a longer scaffolding time.

<div><h4>CTA-determined tricuspid annular dilatation is associated with persistence of tricuspid regurgitation after transcatheter aortic valve replacement.</h4><i>Löw K, Steffen J, Theiss H, Orban M, ... Braun D, Deseive S</i><br /><b>Aim</b><br />The aim of this study was to analyse the predictive value of CTA-determined tricuspid annular dilatation (TAD) on the persistence of tricuspid regurgitation (TR) in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS) and concomitant at least moderate TR.<br /><b>Methods and results</b><br />288 consecutive patients treated with TAVR due to severe AS and concomitant at least moderate TR at baseline were included in the analysis. As cutoff for TAD, the median value of the CTA-determined, to the body surface area-normalized tricuspid annulus diameter (25.2 mm/m<sup>2</sup>) was used. TAD had no impact on procedural characteristics or outcomes, including procedural death and technical or device failure according to the Valve Academic Research Consortium 3 criteria. However, the primary outcome of the study-TR persistence after TAVR was significantly more frequent in patients with compared to patients without TAD (odds ratio 2.60, 95% confidence interval 1.33-5.16, p < 0.01). Multivariable logistic regression analysis, adjusting for clinical and echocardiographic baseline characteristics, which are known to influence aetiology or severity of TR, confirmed TAD as an independent predictor of TR persistence after TAVR (adjusted odds ratio 2.30, 95% confidence interval 1.20-4.46, p = 0.01). Moreover, 2 year all-cause mortality was significantly higher in patients with persistence or without change of TR compared to patients with TR improvement (log-rank p < 0.01).<br /><b>Conclusion</b><br />In patients undergoing TAVR for severe AS and concomitant at least moderate TR at baseline, TAD is a predictor of TR persistence, which is associated with increased 2-year all-cause mortality.<br /><br />© 2023.

Peng JR, See LC</i><br /><b>Aims</b><br />Patients with type 2 diabetes (T2D) who undergo percutaneous coronary intervention (PCI) are at higher risk of adverse cardiovascular and renal events than nondiabetic patients. However, limited evidence is available regarding the cardiovascular, renal, and limb outcomes of patients with T2D after PCI and who were treated with sodium-glucose cotransporter-2 inhibitors (SGLT2i). We compare the specified outcomes in patients with T2D after PCI who were treated with SGLT2i versus dipeptidyl peptidase-4 inhibitors (DPP4i).<br /><b>Methods and results</b><br />In this nationwide retrospective cohort study, we identified 4,248 and 37,037 consecutive patients with T2D who underwent PCI with SGLT2i and DPP4i, respectively, for May 1, 2016, to December 31, 2019. We used propensity score matching (PSM) to balance the covariates between study groups. After PSM, SGLT2i and DPP4i were associated with comparable risks of ischemic stroke, acute myocardial infarction, and lower limb amputation. However, SGLT2i was associated with significantly lower risks of heart failure hospitalization (HFH; 1.35% per year vs. 2.28% per year; hazard ratio [HR]: 0.60; P = 0.0001), coronary revascularization (2.33% per year vs. 3.36% per year; HR: 0.69; P = 0.0003), composite renal outcomes (0.10% per year vs. 1.05% per year; HR: 0.17; P < 0.0001), and all-cause mortality (2.27% per year vs. 3.80% per year, HR: 0.60; P < 0.0001) than were DPP4i.<br /><b>Conclusions</b><br />Our data indicated that SGLT2i, compared with DPP4i, were associated with lower risks of HFH, coronary revascularization, composite renal outcomes, and all-cause mortality for patients with T2D after PCI.

Other objectives were to evaluate 1) whether PMAE affect mortality predicted by the SYNTAX score II 2020 (SSII-2020) and 2) whether optimal medical therapy (OMT) positively affects the prognosis of patients with non-fatal PMAE.<br /><b>Methods</b><br />The association between 10-year mortality and non-fatal PMAE occurring within 30 days of PCI or CABG in patients with three-vessel disease and/or left main disease enrolled in the SYNTAXES study was investigated.<br /><b>Results</b><br />The main findings are that non-fatal PMAE occurred less frequently following PCI than CABG (11.2% vs 28.2%; p<0.001) and that non-fatal PMAE were an independent predictor of all-cause mortality in the first year post-procedure, but not at 5 or 10 years, in both treatment modalities. PMAE substantially alter the individual predictions of 10-year mortality by the SSII-2020. In patients with non-fatal PMAE, OMT may provide survival benefits during the first year post-procedure as well as in the long term.<br /><b>Conclusions</b><br />In patients with complex CAD, non-fatal PMAE were more common following CABG than PCI, but their prognostic impact was similar, being significant in the first year and then diminishing out to 10 years. Patients with non-fatal PMAE may therefore require more careful follow-up and additional preventive treatment in the first year post-procedure.<br /><br /><br /><br /><small>EuroIntervention: 12 Jan 2023; epub ahead of print</small></div>

<div><h4>PRECISE-DAPT and ARC-HBR Predict in-Hospital Outcomes in Patients Who Underwent Percutaneous Coronary Intervention.</h4><i>Kadiyala V, Long S, Has P, Lima FV, ... Aronow HD, Abbott JD</i><br /><AbstractText>Bleeding events result in morbidity and mortality in patients who underwent percutaneous coronary intervention (PCI). There are limited data on the predicting bleeding complications in patients who underwent stent implantation and subsequent dual antiplatelet therapy (PRECISE-DAPT) and Academic Research Consortium for High Bleeding Risk (ARC-HBR) scores\' ability to predict in-hospital outcomes in patients who underwent PCI. Consecutive patients who underwent PCI at tertiary centers from January 2016 to March 2018 were identified and the bleeding risk scores were calculated. The primary end point was the National Cardiovascular Data Registry-defined in-hospital bleeding stratified by low versus high predicted bleeding risk. The major and net adverse cardiovascular events were also examined. The discriminatory ability of the risk models was determined using receiver operating characteristic curves. Among 3,659 patients studied, the in-hospital major bleeding was 3.3% (n = 121). The patients characterized as high bleeding risk by either criterion had significantly higher bleeding rates than those meeting the low-risk criteria (ARC-HBR 5.4% vs 3.3%, p <0.001; PRECISE-DAPT 5.8% vs 2.4%, p <0.001), and higher major adverse cardiovascular events and net adverse clinical events. These risk estimates showed moderate and similar predictive ability (ARC-HBR high-risk area under the receiver operating characteristic curve [AUC] 0.62, PRECISE-DAPT ≥25 AUC 0.61, p = 0.49), with no incremental benefit to adding the estimates (AUC 0.60). The subgroup analysis revealed that women had higher bleeding rates than men (5.53% vs 2.39%, p <0.001); however, the predictive ability of the criteria were similar in women and men. The patients identified as having a high bleeding risk by the PRECISE-DAPT and the ARC-HBR criteria before PCI are at high risk for in-hospital bleeding and adverse outcomes independent of gender. The 2 scores have moderate predictive ability for bleeds. Further study is needed to determine strategies to reduce risk in this population.</AbstractText><br /><br />Copyright © 2022 Elsevier Inc.

<div><h4>Incidence, Predictors, and Outcomes of Major Bleeding Among Patients Hospitalized With Acute Heart Failure.</h4><i>Abramov D, Kobo O, Gorodeski EZ, Rana JS, ... Sauer AJ, Mamas MA</i><br /><AbstractText>Acute heart failure (AHF) is a common etiology of hospitalization and is associated with morbidity, including bleeding. In this study, the authors sought to assess the incidence, types, and associates of major bleeding in patients hospitalized with AHF. The National Inpatient Sample from October 2015 to December 2018 was used to identify patients with AHF. The incidence of common bleeding etiologies, and patient demographics, co-morbidities, associated acute cardiac diagnoses, and invasive procedures, were identified. The multivariable logistic regression was used to identify predictors of bleeding and the association of bleeding episodes with inpatient mortality. During the study period, 1,106,634 patients were admitted with a primary diagnosis of AHF, of whom 58,955 (5.3%) had an episode of bleeding. Common bleeding sources were gastrointestinal (25.7%), hematuria (24%), respiratory (23.6%), and procedure-related bleeding (2.5%). Major bleeding was more common in patients with AHF with preserved ejection fraction (odds ratio 1.14, confidence interval 1.12 to 1.16, p <0.001) versus AHF with reduced ejection fraction and in men (odds ratio 1.3, confidence interval 1.29 to 1.31, p <0.001). Major bleeding was associated with higher mortality (7.0% vs 2.4%, p <0.001), longer length of stay (7 vs 4 days, p <0.001), and higher inpatient costs ($49,658 vs $27,636, p <0.001). In conclusion, major bleeding occurs in 5.3% of patients hospitalized with AHF and is associated with higher inpatient mortality and costs and longer length of stay.</AbstractText><br /><br />Copyright © 2022 The Author(s).

<div><h4>Comparing a strategy of sirolimus-eluting balloon treatment to drug-eluting stent implantation in de novo coronary lesions in all-comers: Design and rationale of the SELUTION DeNovo Trial.</h4><i>Spaulding C, Krackhardt F, Bogaerts K, Urban P, ... Morice MC, Eccleshall S</i><br /><b>Background</b><br />Drug eluting stents (DES) are associated with a 2% to 4% annual rate of target lesion failure through 5-to-10-year follow-up. The presence of a metallic protheses is a trigger for neo-atherosclerosis and very late stent thrombosis. A \"leave nothing behind\" strategy using Drug Coated Balloons has been suggested; however, paclitaxel coated balloons are only recommended in selected indications. Recently a novel sirolimus eluting balloon, the SELUTION SLR <sup>TM</sup> 014 PTCA balloon (SEB) (M.A. MedAlliance SA, Nyon, Switzerland) has been developed.<br /><b>Hypothesis</b><br />A strategy of percutaneous coronary intervention (PCI) with SEB and provisional DES is non-inferior to a strategy of systematic DES on target vessel failure (TVF) at one and five years. If non-inferiority is met at 5 years, superiority will be tested.<br /><b>Design</b><br />SELUTION DeNovo is a multi-center international open-label randomized trial. Subjects meeting eligibility criteria are randomized 1:1 to treatment of all lesions with either SEB and provisional DES or systematic DES. Major inclusion criteria are PCI indicated for ≥1 lesion considered suitable for treatment by either SEB or DES and clinical presentation with chronic coronary syndrome, unstable angina or non-ST segment elevation (NSTEMI). There is no limitation in the number of lesions to be treated. Target lesions diameters are between 2 and 5 mm. Major exclusion criteria are lesions in the left main artery, chronic total occlusions, ST segment elevation myocardial infarction and unstable NSTEMI. 3326 patients will be included in 50 sites in Europe and Asia. TVF rates and their components will be determined at 30 days, 6 months and annually up to 5 years post-intervention. Among secondary endpoints, bleeding events, cost-effectiveness data and net clinical benefits will be assessed.<br /><b>Summary</b><br />SELUTION DeNovo trial is an open-label, multi-center international randomized trial comparing a strategy of PCI with SEB and provisional DES to a strategy of PCI with systematic DES on TVF at one and five years. Non-inferiority will be tested at one and five years. If non-inferiority is met at five years, superiority will be tested.<br /><br />Copyright © 2023.

<div><h4>Plasma levels of CCL21, but not CCL19, independently predict future coronary events in a prospective population-based cohort.</h4><i>Katra P, Hennings V, Nilsson J, Engström G, ... Bengtsson E, Björkbacka H</i><br /><b>Background:</b><br/>and aims</b><br />The homeostatic chemokines CCL21 and CCL19 have been explored as biomarkers in cardiovascular disease prediction in patients with established cardiovascular disease, but associations between these chemokines and first-time coronary event incidence have not been investigated before. Here, we explored associations between CCL21 or CCL19 and first-time incident coronary events in the general population-based Malmö Diet and Cancer cohort with two decades of follow-up.<br /><b>Methods</b><br />CCL21 and CCL19 levels in plasma were analysed with ELISA and proximity extension assay and associations with disease incidence were explored with conditional logistic regression in a nested case-control cohort (CCL21; n = 676) and with Cox regression in a population-based cohort (CCL19; n = 4636).<br /><b>Results</b><br />High CCL21 levels in plasma were associated with incident first-time coronary events independently of traditional risk factors (odds ratio of 2.64 with 95% confidence interval 1.62-4.31, p < 0.001, comparing the highest versus the lowest tertile of CCL21), whereas CCL19 was not. CCL19 was, however, associated with incident heart failure, as well as increased all-cause, cardiovascular and cancer mortality independently of age and sex.<br /><b>Conclusions</b><br />Even though CCL21 and CCL19 both signal through CCR7, these chemokines may not be interchangeable as disease predictors and CCL21 could be used for prediction of future coronary events in individuals without any previous coronary heart disease history.<br /><br />Copyright © 2023 The Authors.

<div><h4>Nonobstructive coronary atherosclerosis is associated with adverse prognosis among patients diagnosed with myocardial infarction without obstructive coronary arteries.</h4><i>Tsaban G, Peles I, Barrett O, Abramowitz Y, ... Zahger D, Koifman E</i><br /><b>Background:</b><br/>and aims</b><br />The prognostic impact of nonobstructive coronary artery disease (CAD), as opposed to normal coronary arteries, on long-term outcomes of patients with myocardial infarction with no obstructive coronary arteries (MINOCA) is unclear. We aimed to address the association between nonobstructive-CAD and major adverse events (MAE) following MINOCA.<br /><b>Methods</b><br />We conducted a retrospective cohort study of consecutive MINOCA patients admitted to a large referral medical center between 2005 and 2018. Patients were classified according to coronary angiography as having either normal-coronaries or nonobstructive-CAD. The primary outcome was MAE, defined as the composite of all-cause mortality and recurrent acute coronary syndrome (ACS).<br /><b>Results</b><br />Of the 1544 MINOCA patients, 651 (42%) had normal coronaries, and 893 (58%) had CAD. The mean age was 61.2 ± 12.6 years, and 710 (46%) were females. Nonobstructive-CAD patients were older and less likely to be females, with higher rates of diabetes, hypertension, dyslipidemia, atrial fibrillation, and chronic renal-failure (p < 0.05). At a median follow-up of 7 years, MAE occurred in 203 (23%) patients and 67 (10%) patients in the nonobstructive-CAD and normal-coronaries groups, respectively (p < 0.01). In multivariable models, nonobstructive -CAD was significantly associated with long-term MAE [adjusted-hazard-ratio (aHR):1.67, 95% confidence-interval (95%CI):1.25-2.23; p < 0.001]. Other factors associated with a higher MAE-risk were older-age (aHR:1.05,95%CI:1.03-1.06; p < 0.001) and left ventricular ejection-fraction<40% (aHR:3.04,95%CI:2.03-4.57; p < 0.001), while female-sex (aHR:0.72, 95%CI: 0.56-0.94; p=0.014) and sinus rhythm at presentation (aHR:0.66, 95%CI: 0.44-0.98; p=0.041) were associated with lower MAE-risk.<br /><b>Conclusions</b><br />In MINOCA, nonobstructive-CAD is independently associated with a higher MAE-risk than normal-coronaries. This finding may promote risk-stratification of patients with nonobstructive-CAD-MINOCA who require tighter medical follow-up and treatment optimization.<br /><br />Copyright © 2023 Elsevier B.V.

<div><h4>Aortic Valve Reconstruction With Autologous Pericardium Versus a Bioprosthesis: The Ozaki Procedure in Perspective.</h4><i>Unai S, Ozaki S, Johnston DR, Saito T, ... Blackstone EH, Pettersson GB</i><br /><AbstractText><br /><b>Background:</b><br/>We assessed the Ozaki procedure, aortic valve reconstruction using autologous pericardium, with respect to its learning curve, hemodynamic performance, and durability compared with a stented bioprosthesis. Methods and Results From January 2007 to January 2016, 776 patients underwent an Ozaki procedure at Toho University Ohashi Medical Center. Learning curves, aortic regurgitation (AR), and peak gradient, assessed by serial echocardiograms, valve rereplacement, and survival were investigated. Valve performance and durability were compared with 627 1:1 propensity-matched patients receiving stented bovine pericardial valves implanted from 1982 to 2011 at Cleveland Clinic. Learning curves were observed for aortic clamp and cardiopulmonary bypass times, AR prevalence, and early mortality. Decreased aortic clamp time was observed over the first 300 cases. New surgeons performing parts of the procedure after case 400 resulted in a slight increase in aortic clamp and cardiopulmonary bypass times. Among matched patients, the Ozaki cohort had more AR than the PERIMOUNT cohort (severe AR at 1 and 6 years, 0.58% and 3.6% versus 0.45% and 1.0%, respectively; <i>P</i>[trend]=0.006), although with a steep learning curve. Peak gradient showed the opposite trend: 14 and 17 mm Hg for Ozaki and 24 and 28 mm Hg for PERIMOUNT at these times (<i>P</i>[trend]<i><</i>0.001). Freedom from rereplacement was similar (<i>P</i>=0.491). Survival of the Ozaki cohort was 85% at 6 years. <br /><b>Conclusions:</b><br/>Patients undergoing the Ozaki procedure had lower gradients but more recurrent AR than those receiving PERIMOUNT bioprostheses. Although recurrent AR is concerning, results confirm low risk and good midterm performance of the Ozaki procedure, supporting its continued use.</AbstractText><br /><br /><br /><br /><small>J Am Heart Assoc: 11 Jan 2023:e027391; epub ahead of print</small></div>

Williams MC, Lee KK</i><br /><b>Objective</b><br />In patients with acute chest pain who have had myocardial infarction excluded, plasma cardiac troponin I concentrations ≥5 ng/L are associated with risk of future adverse cardiovascular events. We aim to evaluate the association between cardiac troponin and coronary plaque composition in such patients.<br /><b>Methods</b><br />In a prespecified secondary analysis of a prospective cohort study, blinded quantitative plaque analysis was performed on 242 CT coronary angiograms of patients with acute chest pain in whom myocardial infarction was excluded. Patients were stratified by peak plasma cardiac troponin I concentration ≥5 ng/L or <5 ng/L. Associations were assessed using univariable and multivariable logistic regression analyses.<br /><b>Results</b><br />The cohort was predominantly middle-aged (62±12 years) men (69%). Patients with plasma cardiac troponin I concentration ≥5 ng/L (n=161) had a higher total (median 33% (IQR 0-47) vs 0% (IQR 0-33)), non-calcified (27% (IQR 0-37) vs 0% (IQR 0-28)), calcified (2% (IQR 0-8) vs 0% (IQR 0-3)) and low-attenuation (1% (IQR 0-3) vs 0% (IQR 0-1)) coronary plaque burden compared with those with concentrations <5 ng/L (n=81; p≤0.001 for all). Low-attenuation plaque burden was independently associated with plasma cardiac troponin I concentration ≥5 ng/L after adjustment for clinical characteristics (adjusted OR per doubling 1.62 (95% CI 1.17 to 2.32), p=0.005) or presence of any visible coronary artery disease (adjusted OR per doubling 1.57 (95% CI 1.07 to 2.37), p=0.026).<br /><b>Conclusion</b><br />In patients with acute chest pain but without myocardial infarction, plasma cardiac troponin I concentrations ≥5 ng/L are associated with greater burden of low-attenuation coronary plaque.<br /><br />© Author(s) (or their employer(s)) 2023.

Su P, Zhao L</i><br /><b>Background</b><br />Thrombospondin-1, a large matricellular glycoprotein, exerts multifaced biological effects on the cardiovascular system and is correlated with cardiovascular diseases. Its plasma levels and correlation with in-hospital prognosis are yet unclear in the acute coronary syndrome population. The present study aimed to evaluate the correlation between thrombospondin-1 plasma levels and in-hospital adverse events in patients with acute coronary syndrome.<br /><b>Methods</b><br />This is a cross-sectional study. A total of 341 inpatients with acute coronary syndrome were recruited in Beijing Chaoyang Hosipital from May 2021 to November 2021. The thrombospondin-1 plasma levels were measured, and the in-hospital major adverse cardiovascular events, including all-cause death, recurrent ischemia, arrhythmias, and heart failure, were recorded. This correlation was assessed by logistic regression analysis.<br /><b>Results</b><br />The thrombospondin-1 plasma levels were higher in patients with non-ST-elevation myocardial infarction and ST-elevation myocardial infarction compared to those in unstable angina (P < 0.001), while the differences between the two different types of myocardial infarction were not statistically different. Thrombospondin-1 plasma levels were correlated with GRACE score, leukocytes, neutrophils, platelets, troponin I, creatine kinase-MB, D-dimer, C-reactive protein, erythrocyte sedimentation rate, and log10 brain natriuretic peptide. Furthermore, thrombospondin-1 plasma levels were associated with the in-hospital major adverse cardiovascular events in patients with acute coronary syndrome (P = 0.001).<br /><b>Conclusions</b><br />Thrombospondin-1 plasma levels were higher in patients with myocardial infarction than those in unstable angina.

Escaned J, Piek JJ</i><br /><b>Objective</b><br />The role of combined FFR/CFR measurements in decision-making on coronary revascularization remains unclear. DEFINE-FLOW prospectively assessed the relationship of FFR/CFR agreement with 2-year major adverse cardiac event (MACE) and target vessel failure (TVF) rates, and uniquely included core-laboratory analysis of all pressure and flow tracings. We aimed to document the impact of core-laboratory analysis on lesion classification, and the relationship between core-laboratory fractional flow reserve (FFR) and coronary flow reserve (CFR) values with clinical outcomes and angina burden during follow-up.<br /><b>Methods</b><br />In 398 vessels (348 patients) considered for intervention, ≥1 coronary pressure/flow tracing was approved by the core-laboratory. Revascularization was performed only when both FFR(≤0.80) and CFR(<2.0) were abnormal, all others were treated medically.<br /><b>Results</b><br />MACE was lowest for concordant normal FFR/CFR, but was not significantly different compared with either discordant group (low FFR/normal CFR: HR:1.63; 95%CI:0.61-4.40; P = 0.33; normal FFR/low CFR: HR:1.81; 95%CI:0.66-4.98; P = 0.25). Moreover, MACE did not differ between discordant groups treated medically and the concordant abnormal group undergoing revascularization (normal FFR/low CFR: HR:0.63; 95%CI:0.23-1.73;P = 0.37; normal FFR/low CFR: HR:0.70; 95%CI:0.22-2.21;P = 0.54). Similar findings applied to TVF.<br /><b>Conclusions</b><br />Patients with concordantly normal FFR/CFR have very low 2-year MACE and TVF rates. Throughout follow-up, there were no differences in event rates between patients in whom revascularization was deferred due to preserved CFR despite reduced FFR, and those in whom PCI was performed due to concordantly low FFR and CFR. These findings question the need for routine revascularization in vessels showing low FFR but preserved CFR.<br /><b>Clinical trial registration</b><br />ClinicalTrials.govNCT02328820.<br /><br />Copyright © 2023.

<div><h4>Acute aortic dissection.</h4><i>Carrel T, Sundt TM, von Kodolitsch Y, Czerny M</i><br /><AbstractText>Although substantial progress has been made in the prevention, diagnosis, and treatment of acute aortic dissection, it remains a complex cardiovascular event, with a high immediate mortality and substantial morbidity in individuals surviving the acute period. The past decade has allowed a leap forward in understanding the pathophysiology of this disease; the existing classifications have been challenged, and the scientific community moves towards a nomenclature that is likely to unify the current definitions according to morphology and function. The most important pathophysiological pathway, namely the location and extension of the initial intimal tear, which causes a disruption of the media layer of the aortic wall, together with the size of the affected aortic segments, determines whether the patient should undergo emergency surgery, an endovascular intervention, or receive optimal medical treatment. The scientific evidence for the management and follow-up of acute aortic dissection continues to evolve. This Seminar provides a clinically relevant overview of potential prevention, diagnosis, and management of acute aortic dissection, which is the most severe acute aortic syndrome.</AbstractText><br /><br />Copyright © 2023 Elsevier Ltd.

This study aimed to investigate the use of VersaCross RF transseptal wire system (Baylis Medical) to improve procedural efficiency of left atrial appendage closure (LAAC) compared to the standard RF needle-based workflow.<br /><b>Methods</b><br />Eighty-one LAAC procedures using WATCHMAN FLX were retrospectively analyzed comparing the standard RF needle-based workflow to a RF wire-based workflow. Study primary endpoint was time to WATCHMAN device release, and secondary endpoints were transseptal puncture time, LAAC success, fluoroscopy use, and procedural complications.<br /><b>Results</b><br />Twenty-five cases using standard RF needle-based workflow were compared to 56 cases using the RF wire-based workflow. Baseline patient characteristics were similar between both groups. LAAC was successful in all patients with no differences in intraprocedural complication rates (p = 0.40). Transseptal puncture time was 1.3 min faster using the RF wire-based workflow compared to the standard RF needle-based workflow (6.5 ± 2.3  vs. 7.8 ± 2.3 min, p = 0.02). Overall, time to final WATCHMAN device release was 4.5 min faster with the RF wire-based workflow compared to the RF needle-based workflow (24.6 ± 5.6 vs. 29.1 ± 9.6 min, p = 0.01). Fluoroscopy time was 21% lower using the RF wire-based workflow (7.6 ± 2.8 vs. 9.6 ± 4.4 min; p = 0.05) and fluoroscopy dose was 67% lower (47.1 ± 35.3 vs. 144.9 ± 156.9 mGy, p = 0.04) and more consistent (F-test, p ˂ 0.0001).<br /><b>Conclusions</b><br />The RF wire-based workflow streamlines LAAC procedures, improving LAAC efficiency and safety by reducing fluoroscopy, device exchanges, and delivery sheath manipulation.<br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 10 Jan 2023; epub ahead of print</small></div>

Clinical guidelines call for documenting ischaemia in patients with SAP prior to elective PCI. The Japanese Ministry of Health, Labour and Welfare introduced a new reimbursement policy in April 2018 to promote the appropriate and judicious implementation of PCI. The 2018 reimbursement changes clarified the required proof of ischaemia. Tests to evaluate functional ischaemia and coronary stenosis have been added as a requirement for reimbursement. We examined whether this reimbursement revision had an impact on PCI procedures for SAP in Japan.<br /><b>Methods</b><br />We used administrative claims data in Japan\'s Diagnosis Procedure Combination database from April 2014 through March 2020. We used interrupted time series analyses with a control to ascertain the impacts on elective PCI procedures before and after the Japanese reimbursement revision. The primary outcome was the change in elective PCI procedures per month. Emergent PCI procedures served as a control group.<br /><b>Results</b><br />A total of 773 240 PCI procedures were identified between April 2014 and March 2020: 388 817 and 180 462 elective PCIs before and after the reimbursement revision, respectively. After the 2018 reimbursement revision, significant trend changes were found in elective PCI procedures per month (-106.3, 95% CI -155.8 to -56.8, p<0.01), while the number of emergent PCIs remained stable throughout the study period.<br /><b>Conclusions</b><br />After revising the reimbursement tariff for elective PCIs in 2018, there was a significant reduction in elective PCI procedures per month.<br /><br />© Author(s) (or their employer(s)) 2023.
