<div><h4>Periprocedural Mortality in Chronic Total Occlusion Percutaneous Coronary Intervention: Insights From the PROGRESS-CTO Registry.</h4><i>Simsek B, Rempakos A, Kostantinis S, Karacsonyi J, ... Burke MN, Brilakis ES</i><br /><b>Background</b><br />Death is a rare but devastating complication of chronic total occlusion (CTO) percutaneous coronary intervention.<br /><b>Methods</b><br />We examined the clinical characteristics and procedural outcomes of patients who died periprocedurally in the Prospective Global Registry for the Study of CTO Interventions (PROGRESS-CTO).<br /><b>Results</b><br />Of the 12 928 patients who underwent CTO percutaneous coronary intervention between 2012 and 2022, 52 (0.4%) died during the index hospitalization. Patients who died were more likely to have a history of heart failure (43% versus 28%; <i>P</i>=0.023). The J-CTO ([Multicenter CTO Registry of Japan]; 2.8±1.1 versus 2.4±1.3; <i>P</i>=0.019), PROGRESS-CTO mortality (2.6±0.9 versus 1.6±1.1; <i>P</i>&lt;0.001), and PROGRESS-CTO pericardiocentesis (2.9±1.1 versus 1.9±1.3; <i>P</i>&lt;0.001) scores were higher in patients who died. In these patients, the use of left ventricular assist devices was also higher (41% versus 3.5%; <i>P</i>&lt;0.001), and retrograde crossing was more often the first crossing strategy (33% versus 13%; <i>P</i>&lt;0.001). The cause of death was cardiac in 43 patients (83%) and noncardiac in 9 patients (17%). Complications leading to cardiac death were: tamponade in 30 patients (58%), acute myocardial infarction in 9 (17.3%), and cardiac arrest/shock in 4 (7.7%). Noncardiac causes of death were: stroke in 3 (5.8%), renal failure in 2 (3.8%), respiratory distress in 2 (3.8%), and hemorrhagic shock in 2 (3.8%).<br /><b>Conclusions</b><br />Approximately 0.4% of patients who underwent CTO percutaneous coronary intervention died during the index hospitalization. The main cause of death was tamponade in 58%. PROGRESS-CTO complication scores might help in risk stratification and procedural planning in patients undergoing CTO percutaneous coronary intervention.<br /><b>Registration</b><br />URL: https://www.<br /><b>Clinicaltrials</b><br />gov; Unique Identifier: NCT02061436.<br /><br /><br /><br /><small>Circ Cardiovasc Interv: 01 Jun 2023:e012977; epub ahead of print</small></div>

<div><h4>Coronary Microvascular Disease in Contemporary Clinical Practice.</h4><i>Smilowitz NR, Toleva O, Chieffo A, Perera D, Berry C</i><br /><AbstractText>Coronary microvascular disease (CMD) causes myocardial ischemia in a variety of clinical scenarios. Clinical practice guidelines support routine testing for CMD in patients with ischemia with nonobstructive coronary artery disease. Invasive testing to identify CMD requires Doppler or thermodilution measures of flow to determine the coronary flow reserve and measures of microvascular resistance. Acetylcholine coronary reactivity testing identifies concomitant endothelial dysfunction, microvascular spasm, or epicardial coronary spasm. Comprehensive testing may improve symptoms, quality of life, and patient satisfaction by establishing a diagnosis and guiding-targeted medical therapy and lifestyle measures. Beyond ischemia with nonobstructive coronary artery disease, testing for CMD may play a role in patients with acute myocardial infarction, angina following coronary revascularization, heart failure with preserved ejection fraction, Takotsubo syndrome, and after heart transplantation. Additional education and provider awareness of CMD and its role in cardiovascular disease is needed to improve patient-centered outcomes of ischemic heart disease.</AbstractText><br /><br /><br /><br /><small>Circ Cardiovasc Interv: 01 Jun 2023:e012568; epub ahead of print</small></div>

<div><h4>Interventional Versus Conservative Strategy in Patients With Spontaneous Coronary Artery Dissections: Insights From DISCO Registry.</h4><i>Benenati S, Giacobbe F, Zingarelli A, Macaya F, ... Porto I, DISCO Collaborators</i><br /><b>Background</b><br />The optimal management of patients with spontaneous coronary artery dissection remains debated.<br /><b>Methods</b><br />Patients enrolled in the DISCO (Dissezioni Spontanee Coronariche) Registry up to December 2020 were included. The primary end point was major adverse cardiovascular events, a composite of all-cause death, nonfatal myocardial infarction, and repeat percutaneous coronary intervention (PCI). Independent predictors of PCI and medical management were investigated.<br /><b>Results</b><br />Among 369 patients, 129 (35%) underwent PCI, whereas 240 (65%) were medically managed. ST-segment-elevation myocardial infarction (68% versus 35%, <i>P</i>&lt;0.001), resuscitated cardiac arrest (9% versus 3%, <i>P</i>&lt;0.001), proximal coronary segment involvement (32% versus 7%, <i>P</i>&lt;0.001), and Thrombolysis in Myocardial Infarction flow 0 to 1 (54% versus 20%, <i>P</i>&lt;0.001) were more frequent in the PCI arm. In-hospital event rates were similar. Between patients treated with PCI and medical therapy, there were no differences in terms of major adverse cardiovascular events at 2 years (13.9% versus 11.7%, <i>P</i>=0.467), all-cause death (0.7% versus 0.4%, <i>P</i>=0.652), myocardial infarction (9.3% versus 8.3%, <i>P</i>=0.921) and repeat PCI (12.4% versus 8.7%, <i>P</i>=0.229). ST-segment-elevation myocardial infarction at presentation (odds ratio [OR], 3.30 [95% CI, 1.56-7.12]; <i>P</i>=0.002), proximal coronary segment involvement (OR, 5.43 [95% CI, 1.98-16.45]; <i>P</i>=0.002), Thrombolysis in Myocardial Infarction flow grade 0 to 1 and 2 (respectively, OR, 3.22 [95% CI, 1.08-9.96]; <i>P</i>=0.038; and OR, 3.98 [95% CI, 1.38-11.80]; <i>P</i>=0.009) and luminal narrowing (OR per 5% increase, 1.13 [95% CI, 1.01-1.28]; <i>P</i>=0.037) were predictors of PCI, whereas the 2B-angiographic subtype predicted medical management (OR, 0.25 [95% CI, 0.07-0.83]; <i>P</i>=0.026).<br /><b>Conclusions</b><br />Clinical presentation and procedural variables drive the choice of the initial therapeutic approach in spontaneous coronary artery dissection. If PCI is needed, it seems to be associated with a similar risk of short-to-mid-term adverse events compared to medical treatment.<br /><b>Registration</b><br />URL: https://www.<br /><b>Clinicaltrials</b><br />gov; Unique identifier: NCT04415762.<br /><br /><br /><br /><small>Circ Cardiovasc Interv: 01 Jun 2023:e012780; epub ahead of print</small></div>

<div><h4>Sex and age-related differences in outcomes of patients with acute myocardial infarction: MINOCA versus MIOCA.</h4><i>Canton L, Fedele D, Bergamaschi L, Foà A, ... Paolisso P, Pizzi C</i><br /><b>Background</b><br />To evaluate the impact of sex on acute myocardial infarction (AMI) patients\' clinical presentation and outcomes, comparing those with non-obstructive and obstructive coronary arteries (MINOCA vs MIOCA).<br /><b>Methods</b><br />We enrolled 2455 patients with AMI undergoing coronary angiography from January 2017 to September 2021. Patients were divided according to the type of AMI and sex: male (n=1593) and female (n=607) in MIOCA; male (n=87) and female (n=168) in MINOCA. Each cohort was further stratified based on age (≤/&gt; 70 years). The primary endpoint (MAE) was a composite of all-cause death, recurrent AMI, and hospitalization for heart failure (HF) at follow-up. Secondary outcomes included: all-cause and cardiovascular death, recurrent AMI, HF re-hospitalization and stroke.<br /><b>Results</b><br />MINOCA patients were more likely to be females compared to MIOCA ones (p&lt;0.001). The median follow-up was 28 [15-41] months. The unadjusted incidence of MAE was significantly higher in females compared to males, both in MINOCA [45 (26.8%) vs 12 (13.8%); p=0.018] and MIOCA cohorts [203 (33.4%) vs 428 (26.9%); p=0.002]. Age was an independent predictor of MAE in both cohorts. Among MINOCA patients, females ≤70-year-old had a higher incidence of MAE [18 (23.7%) vs 4 (5.9%); p=0.003] compared to male peers, mainly driven by a higher rate of re-hospitalization for HF (p=0.045) and recurrence of AMI (p=0.006). Only in this sub-group of MINOCA patients, female sex was an independent predictor of MAE (HR=3.09; 95%CI: 1.02-9.59; p=0.040). MINOCA females ≤70-year-old had worse outcomes than MIOCA female peers.<br /><b>Conclusion</b><br />MINOCA females ≤70-year-old had a significantly higher incidence of MAE, compared to males and MIOCA female peers, likely due to the different pathophysiology of the ischemic event.<br /><b>Trial registration</b><br />data were part of the ongoing observational study AMIPE: Acute Myocardial Infarction, Prognostic and Therapeutic Evaluation.

<div><h4>IL-6 helps weave the inflammatory web during acute coronary syndromes.</h4><i>Nakao T, Libby P</i><br /><AbstractText>The cytokine IL-6 has well-known proinflammatory roles in aging and ischemic heart disease. In this issue of the JCI, Alter and colleagues used mouse experiments and human tissue to investigate the source of IL-6 following myocardial infarction. The authors showed that cardiac fibroblasts produced IL-6 after coronary ligation in mice and proposed the existence of a pathway involving adenosine signaling via the adenosine A2b receptor. The findings underscore the complexity of IL-6 biology in ischemic heart disease and identify an adenosine/IL-6 pathway that warrants consideration for targeting as a modulator of cardiovascular risk.</AbstractText><br /><br /><br /><br /><small>J Clin Invest: 01 Jun 2023; 133</small></div>

<div><h4>Coronary microvascular health in symptomatic patients with prior COVID-19 infection: an updated analysis.</h4><i>Ahmed AI, Al Rifai M, Alahdab F, Saad JM, ... Zoghbi WA, Al-Mallah MH</i><br /><b>Aims</b><br />Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is associated with endothelial dysfunction. We aimed to determine the effects of prior coronavirus disease 2019 (COVID-19) on the coronary microvasculature accounting for time from COVID-19, disease severity, SARS-CoV-2 variants, and in subgroups of patients with diabetes and those with no known coronary artery disease.<br /><b>Methods and results</b><br />Cases consisted of patients with previous COVID-19 who had clinically indicated positron emission tomography (PET) imaging and were matched 1:3 on clinical and cardiovascular risk factors to controls having no prior infection. Myocardial flow reserve (MFR) was calculated as the ratio of stress to rest myocardial blood flow (MBF) in mL/min/g of the left ventricle. Comparisons between cases and controls were made for the odds and prevalence of impaired MFR (MFR &lt; 2). We included 271 cases matched to 815 controls (mean ± SD age 65 ± 12 years, 52% men). The median (inter-quartile range) number of days between COVID-19 infection and PET imaging was 174 (58-338) days. Patients with prior COVID-19 had a statistically significant higher odds of MFR &lt;2 (adjusted odds ratio 3.1, 95% confidence interval 2.8-4.25 P &lt; 0.001). Results were similar in clinically meaningful subgroups. The proportion of cases with MFR &lt;2 peaked 6-9 months from imaging with a statistically non-significant downtrend afterwards and was comparable across SARS-CoV-2 variants but increased with increasing severity of infection.<br /><b>Conclusion</b><br />The prevalence of impaired MFR is similar by duration of time from infection up to 1 year and SARS-CoV-2 variants, but significantly differs by severity of infection.<br /><br />© The Author(s) 2023.

<div><h4>Percutaneous Coronary Intervention vs Coronary Artery Bypass Graft Surgery for Left Main Disease in Patients With and Without Acute Coronary Syndromes: A Pooled Analysis of 4 Randomized Clinical Trials.</h4><i>Gaba P, Christiansen EH, Nielsen PH, Murphy SA, ... Holm NR, Bergmark BA</i><br /><b>Importance</b><br />Patients with left main coronary artery disease presenting with an acute coronary syndrome (ACS) represent a high-risk and understudied subgroup of patients with atherosclerosis.<br /><b>Objective</b><br />To assess clinical outcomes after PCI vs CABG in patients with left main disease with vs without ACS.<br /><b>Design, setting, and participants</b><br />Data were pooled from 4 trials comparing PCI with drug-eluting stents vs CABG in patients with left main disease who were considered equally suitable candidates for either strategy (SYNTAX, PRECOMBAT, NOBLE, and EXCEL). Patients were categorized as presenting with or without ACS. Kaplan-Meier event rates through 5 years and Cox model hazard ratios were generated, and interactions were tested. Patients were enrolled in the individual trials from 2004 through 2015. Individual patient data from the trials were pooled and reconciled from 2020 to 2021, and the analyses pertaining to the ACS subgroup were performed from March 2022 through February 2023.<br /><b>Main outcomes and measures</b><br />The primary outcome was death through 5 years. Secondary outcomes included cardiovascular death, spontaneous myocardial infarction (MI), procedural MI, stroke, and repeat revascularization.<br /><b>Results</b><br />Among 4394 patients (median [IQR] age, 66 [59-73] years; 3371 [76.7%] male and 1022 [23.3%] female) randomized to receive PCI or CABG, 1466 (33%) had ACS. Patients with ACS were more likely to have diabetes, prior MI, left ventricular ejection fraction less than 50%, and higher SYNTAX scores. At 30 days, patients with ACS had higher all-cause death (hazard ratio [HR], 3.40; 95% CI, 1.81-6.37; P &lt; .001) and cardiovascular death (HR, 3.21; 95% CI, 1.69-6.08; P &lt; .001) compared with those without ACS. Patients with ACS also had higher rates of spontaneous MI (HR, 1.70; 95% CI, 1.25-2.31; P &lt; .001) through 5 years. The rates of all-cause mortality through 5 years with PCI vs CABG were 10.9% vs 11.5% (HR, 0.93; 95% CI, 0.68-1.27) in patients with ACS and 11.3% vs 9.6% (HR, 1.19; 95% CI, 0.95-1.50) in patients without ACS (P = .22 for interaction). The risk of early stroke was lower with PCI vs CABG (ACS: HR, 0.39; 95% CI, 0.12-1.25; no ACS: HR, 0.35; 95% CI, 0.16-0.75), whereas the 5-year risks of spontaneous MI and repeat revascularization were higher with PCI vs CABG (spontaneous MI: ACS: HR, 1.74; 95% CI, 1.09-2.77; no ACS: HR, 3.03; 95% CI, 1.94-4.72; repeat revascularization: ACS: HR, 1.57; 95% CI, 1.19-2.09; no ACS: HR, 1.90; 95% CI, 1.54-2.33), regardless of ACS status.<br /><br /><b>Conclusion:</b><br/>and relevance</b><br />Among largely stable patients undergoing left main revascularization and with predominantly low to intermediate coronary anatomical complexity, those with ACS had higher rates of early death. Nonetheless, rates of all-cause mortality through 5 years were similar with PCI vs CABG in this high-risk subgroup. The relative advantages and disadvantages of PCI vs CABG in terms of early stroke and long-term spontaneous MI and repeat revascularization were consistent regardless of ACS status.<br /><b>Trial registration</b><br />ClinicalTrials.gov Identifiers: NCT00114972, NCT00422968, NCT01496651, NCT01205776.<br /><br /><br /><br /><small>JAMA Cardiol: 31 May 2023; epub ahead of print</small></div>

<div><h4>Cardiovascular Health by Life\'s Essential 8 and Associations With Coronary Artery Calcium in South Asian American Adults in the MASALA Study.</h4><i>Shah NS, Talegawkar SA, Jin Y, Hussain BM, Kandula NR, Kanaya AM</i><br /><AbstractText>South Asian Americans experience high cardiovascular disease risk. We evaluated the distribution and correlates of cardiovascular health (CVH) summarized by the Life\'s Essential 8 (LE8) score among South Asian adults. In participants of the MASALA (Mediators of Atherosclerosis in South Asians Living in America) study, the association of demographic, social, and cultural factors with LE8 score was evaluated with t tests and analysis of variance. The association of LE8 score with coronary artery calcium (CAC) was evaluated with adjusted logistic regression. There were 556 women (mean age 55.9 years [SD 8.7], mean LE8 score 67.2 (SD 12.6) and 608 men (mean age 57.5 years [SD 9.9], mean LE8 score 61.9 (SD 13.1). Among women and men, the LE8 CVH score was higher in participants with higher annual family income, higher educational attainment, and fewer depressive symptoms. Overall, there was 26% lower odds of any CAC for each 10-point higher LE8 score (odds ratios [OR] 0.74, 95% confidence intervals [CI] 0.66 to 0.83), with similar magnitude of association in women and men. Participants with a high LE8 CVH score had 82% lower odds of CAC (OR 0.18, 95% CI 0.09 to 0.33), and participants with an intermediate LE8 CVH score had 38% lower odds of CAC (OR 0.62, 95% CI 0.41 to 0.94) than did participants with a low LE8 CVH score, with similar findings stratified by gender. In conclusion, in this cohort of South Asian Americans, most adults had suboptimal CVH assessed by the LE8 score. Higher LE8 score correlated with lower odds of any CAC.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Long-Term Outcomes of Patients With Carotid and Aortic Body Tumors.</h4><i>Verghis NM, Brown JA, Yousef S, Aranda-Michel E, ... Singh M, Sultan I</i><br /><AbstractText>Chemodectomas are tumors derived from parasympathetic nonchromaffin cells and are often found in the aortic and carotid bodies. They are generally benign but can cause mass-effect symptoms and have local or distant spread. Surgical excision has been the main curative treatment strategy. The National Cancer Database was reviewed to study all patients with carotid or aortic body tumors from 2004 to 2015. Demographic data, tumor characteristics, treatment strategies, and patient outcomes were examined, split by tumor location. Kaplan-Meier survival estimates were generated for both locations. In total, 248 patients were examined, with 151 having a tumor in the carotid body and 97 having a tumor in the aortic body. Many variables were similar between both tumor locations. However, aortic body tumors were larger than those in the carotid body (477.80 ± 477.58 mm vs 320.64 ± 436.53 mm, p = 0.008). More regional lymph nodes were positive in aortic body tumors (65.52 ± 45.73 vs 35.46 ± 46.44, p &lt;0.001). There were more distant metastases at the time of diagnosis in carotid body tumors (p = 0.003). Chemotherapy was used more for aortic body tumors (p = 0.001); surgery was used more for carotid body tumors (p &lt;0.001). There are slight differences in tumor characteristics and response to treatment. Surgical resection is the cornerstone of management, and radiation can often be considered. In conclusion, chemodectomas are generally benign but can present with metastasis and compressive symptoms that make understanding their physiology and treatment important.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Outcomes of Transcatheter Aortic Valve Implantation in Nonagenarians and Octogenarians (Analysis from the National Inpatient Sample Database).</h4><i>Ismayl M, Aboud Abbasi M, Al-Abcha A, Robertson S, ... Guerrero M, Anavekar NS</i><br /><AbstractText>Risks among nonagenarian (age ≥90 years) and octogenarian (age 80 to 89 years) patients who underwent transcatheter aortic valve implantation (TAVI) compared with clinically similar septuagenarian (age 70 to 79 years) patients remain unclear. This study aimed to assess the outcomes of TAVI in nonagenarians and octogenarians compared with septuagenarians. We conducted a retrospective cohort study using the National Inpatient Sample database to identify patients aged ≥70 years hospitalized for TAVI from 2016 to 2020 and to compare outcomes in nonagenarians and octogenarians versus septuagenarians. The primary outcome was in-hospital mortality. Secondary outcomes included procedural complications, length of stay (LOS), and total costs. The trends in in-hospital outcomes were evaluated. Results were adjusted for demographic/clinical factors. The total cohort included 263,325 patients hospitalized for TAVI, of whom 11.9% were nonagenarians, 51.1% octogenarians, and 37.0% septuagenarians. After adjustment, nonagenarians and octogenarians had higher odds of in-hospital mortality (adjusted odds ratio 1.80, 95% confidence interval 1.34 to 2.41 for nonagenarians; adjusted odds ratio 1.65, 95% confidence interval 1.35 to 2.01 for octogenarians), heart block, permanent pacemaker insertion, stroke, major bleeding, blood transfusion, and palliative care consultation than septuagenarians (all p &lt;0.01). LOS was longer and the total costs were higher for nonagenarians and octogenarians (both p &lt;0.01). Over the study period, in-hospital mortality decreased in nonagenarians (p<sub>trend</sub> = 0.04), and major bleeding, permanent pacemaker insertion, LOS, and costs decreased in all patients aged ≥70 years (p<sub>trend</sub> &lt;0.01). In conclusion, nonagenarians and octogenarians who underwent TAVI have higher rates of mortality and procedure-related complications than clinically similar septuagenarians. Further research is necessary to optimize outcomes in this frail population.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Predictors of target lesion failure after treatment of left main, bifurcation, or chronic total occlusion lesions with ultrathin-strut drug-eluting coronary stents in the ULTRA registry.</h4><i>de Filippo O, Bruno F, Pinxterhuis TH, Gąsior M, ... D\'Ascenzo F, ULTRA Collaborators</i><br /><b>Background</b><br />Data about the long-term performance of new-generation ultrathin-strut drug-eluting stents (DES) in challenging coronary lesions, such as left main (LM), bifurcation, and chronic total occlusion (CTO) lesions are scant.<br /><b>Methods</b><br />The international multicenter retrospective observational ULTRA study included consecutive patients treated from September 2016 to August 2021 with ultrathin-strut (&lt;70 µm) DES in challenging de novo lesions. Primary endpoint was target lesion failure (TLF): composite of cardiac death, target-lesion revascularization (TLR), target-vessel myocardial infarction (TVMI), or definite stent thrombosis (ST). Secondary endpoints included all-cause death, acute myocardial infarction (AMI), target vessel revascularization, and TLF components. TLF predictors were assessed with Cox multivariable analysis.<br /><b>Results</b><br />Of 1801 patients (age: 66.6 ± 11.2 years; male: 1410 [78.3%]), 170 (9.4%) experienced TLF during follow-up of 3.1 ± 1.4 years. In patients with LM, CTO, and bifurcation lesions, TLF rates were 13.5%, 9.9%, and 8.9%, respectively. Overall, 160 (8.9%) patients died (74 [4.1%] from cardiac causes). AMI and TVMI rates were 6.0% and 3.2%, respectively. ST occurred in 11 (1.1%) patients while 77 (4.3%) underwent TLR. Multivariable analysis identified the following predictors of TLF: age, STEMI with cardiogenic shock, impaired left ventricular ejection fraction, diabetes, and renal dysfunction. Among the procedural variables, total stent length increased TLF risk (HR: 1.01, 95% CI: 1-1.02 per mm increase), while intracoronary imaging reduced the risk substantially (HR: 0.35, 95% CI: 0.12-0.82).<br /><b>Conclusions</b><br />Ultrathin-strut DES showed high efficacy and satisfactory safety, even in patients with challenging coronary lesions. Yet, despite using contemporary gold-standard DES, the association persisted between established patient- and procedure-related features of risk and impaired 3-year clinical outcome.<br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 26 May 2023; epub ahead of print</small></div>

Clinical follow-up was available in all subjects. At multivariate analysis, neither a ppMG &gt; 4 mmHg nor a ppMG ≥ 5 mmHg were independently associated with the outcome. Notably, the risk of elevated residual MR (rMR &gt; 2+) was significantly higher in patients belonging to the highest tertile of ppMG (p = 0.009). The association of ppMG &gt; 4 mmHg and rMR ≥ 2+ was strongly and independently associated with adverse events (hazard ratio: 1.98; 95% confidence interval: [1.10-3.58]).<br /><b>Conclusions</b><br />In a real-world cohort of patients suffering DMR and treated with MV-TEER, isolated ppMG was not associated with the outcome at 1-year follow-up.

<div><h4>Reducing Long-Term Mortality Post Transcatheter Aortic Valve Replacement Requires Systemic Differentiation of Patient-Specific Coronary Hemodynamics.</h4><i>Khodaei S, Garber L, Abdelkhalek M, Maftoon N, Emadi A, Keshavarz-Motamed Z</i><br /><AbstractText><br /><b>Background:</b><br/>Despite the proven benefits of transcatheter aortic valve replacement (TAVR) and its recent expansion toward the whole risk spectrum, coronary artery disease is present in more than half of the candidates for TAVR. Many previous studies do not focus on the longer-term impact of TAVR on coronary arteries, and hemodynamic changes to the circulatory system in response to the anatomical changes caused by TAVR are not fully understood. Methods and Results We developed a multiscale patient-specific computational framework to examine the effect of TAVR on coronary and cardiac hemodynamics noninvasively. Based on our findings, TAVR might have an adverse impact on coronary hemodynamics due to the lack of sufficient coronary blood flow during diastole phase (eg, maximum coronary flow rate reduced by 8.98%, 16.83%, and 22.73% in the left anterior descending, left circumflex coronary artery, and right coronary artery, respectively [N=31]). Moreover, TAVR may increase the left ventricle workload (eg, left ventricle workload increased by 2.52% [N=31]) and decrease the coronary wall shear stress (eg, maximum time averaged wall shear stress reduced by 9.47%, 7.75%, 6.94%, 8.07%, and 6.28% for bifurcation, left main coronary artery, left anterior descending, left circumflex coronary artery, and right coronary artery branches, respectively). <br /><b>Conclusions:</b><br/>The transvalvular pressure gradient relief after TAVR might not result in coronary flow improvement and reduced cardiac load. Optimal revascularization strategy pre-TAVR and progression of coronary artery disease after TAVR could be determined by noninvasive personalized computational modeling.</AbstractText><br /><br /><br /><br /><small>J Am Heart Assoc: 26 May 2023:e029310; epub ahead of print</small></div>

<div><h4>Impact of Preoperative Quantitative Flow Ratio of the Left Anterior Descending Artery on Internal Mammary Artery Graft Patency and Midterm Patient Outcomes After Coronary Artery Bypass Grafting.</h4><i>Wang C, Hu Z, Hou Z, Wang Y, ... Feng W, Zhang Y</i><br /><AbstractText><br /><b>Background:</b><br/>In coronary artery bypass grafting, grafting a target vessel with nonsignificant stenosis increases the risk of graft failure. The present study aims to investigate the impact of preoperative quantitative flow ratio (QFR), a novel functional assessment of the coronary artery, on internal mammary artery graft failure rate and midterm patient outcomes. Methods and Results Between January 2016 and January 2020, we retrospectively included 419 patients who underwent coronary artery bypass grafting who had received preoperative angiography and postoperative coronary computed tomographic angiography in our center. QFR of the left anterior descending (LAD) artery was computed based on preoperative angiograms. The primary end point was the failure of the graft on the LAD artery assessed by coronary computed tomographic angiography at 1 year, and the secondary end point was major adverse cardiac and cerebrovascular events including death from any cause, myocardial infarction, stroke, or repeat revascularization. Grafts on functionally nonsignificant LAD arteries (QFR &gt;0.80) had a significantly higher failure rate than those on functionally significant LAD arteries (31.4% versus 7.2%, <i>P</i>&lt;0.001). QFR outperforms degree of stenosis in discriminating graft failure (C statistic, 0.76 versus 0.58). Clinical follow-up (3.6 years, interquartile range [3.3-4.1]) was accomplished in 405 patients, and the rate of major adverse cardiac and cerebrovascular events was significantly higher among patients with functionally nonsignificant LAD arteries (10.1% versus 4.2%; adjusted hazard ratio, 3.08 [95% CI, 1.18-8.06]; <i>P</i>=0.022). <br /><b>Conclusions:</b><br/>In patients receiving internal mammary artery to LAD artery coronary artery bypass grafting, preoperative QFR of the LAD artery of &gt;0.80 was associated with a higher graft failure rate at 1 year and worse patient outcomes at the 3.6-year follow-up.</AbstractText><br /><br /><br /><br /><small>J Am Heart Assoc: 26 May 2023:e029134; epub ahead of print</small></div>

<div><h4>Midterm Outcomes in Patients With Aortic Stenosis Treated With Contemporary Balloon-Expandable and Self-Expanding Valves: Does Valve Size Have an Impact on Outcome?</h4><i>Kalogeras K, Jabbour RJ, Pracon R, Kabir T, ... Dalby M, Panoulas V</i><br /><AbstractText><br /><b>Background:</b><br/>No data currently exist comparing the contemporary iterations of balloon-expandable (BE) Edwards SAPIEN 3/Ultra and the self-expanding (SE) Medtronic Evolut PRO/R34 valves. The aim of the study was the comparison of these transcatheter heart valves with emphasis on patients with small aortic annulus. Methods and Results In this retrospective registry, periprocedural outcomes and midterm all-cause mortality were analyzed. A total of 1673 patients (917 SE versus 756 BE) were followed up for a median of 15 months. A total of 194 patients died (11.6%) during follow-up. SE and BE groups showed similar survival at 1 (92.6% versus 90.6%) and 3 (80.3% versus 85.2%) years (<i>P</i><sub>log-rank</sub>=0.136). Compared with the BE group, patients treated with the SE device had lower peak (16.3±8 mm Hg SE versus 21.9±8 mm Hg BE) and mean (8.8±5 mm Hg SE versus 11.5±5 mm Hg BE) gradients at discharge. Conversely, the BE group demonstrated lower rates of at least moderate paravalvular regurgitation postoperatively (5.6% versus 0.7% for SE and BE valves, respectively; <i>P</i>&lt;0.001). In patients treated with small transcatheter heart valves (≤26 mm for SE and ≤23 mm for BE; N=284 for SE and N=260 for BE), survival was higher among patients treated with SE valves at both 1 (96.7% SE versus 92.1% BE) and 3 (91.8% SE versus 82.2% BE) years (<i>P</i><sub>log-rank</sub>=0.042). In propensity-matched patients treated with small transcatheter heart valve, there remained a trend for higher survival among the SE group at both 1 (97% SE versus 92.3% BE) and 3 years (91.8% SE versus 78.7% BE), <i>P</i><sub>log-rank</sub>=0.096). <br /><b>Conclusions:</b><br/>Real-world comparison of the latest-generation SE and BE devices demonstrated similar survival up to 3 years\' follow-up. In patients with small transcatheter heart valves, there may be a trend for improved survival among those treated with SE valves.</AbstractText><br /><br /><br /><br /><small>J Am Heart Assoc: 26 May 2023:e028038; epub ahead of print</small></div>

Cuculi F, Toggweiler S</i><br /><b>Background</b><br />Growing interest in neuroprotection in transcatheter aortic valve replacement (TAVR) has catalyzed the development of cerebral protection systems (CPS).<br /><b>Objectives</b><br />Report insights from consecutive real-world patients undergoing TAVR with the Sentinel-CPS.<br /><b>Methods</b><br />Patients with severe aortic stenosis undergoing TAVR from April 2019 to May 2022 were enrolled in a prospective registry. The reason for unsuccessful Sentinel-CPS deployment and the amount of debris captured by the filters were prospectively recorded.<br /><b>Results</b><br />The Sentinal CPS was successfully deployed in 330 patients (85%, Group 1). Deployment was not attempted, unsuccessful or only partially successful in 59 patients (15%, Group 2), caused by anatomical factors such as tortuosity, heavy calcification or small dimensions of radial or brachial artery in 46, technical aspects such as puncture failure or dissection in 5 or use of right radial access for the pigtail in 6. Debris was captured in 98% of patients in Group 1. In 40%, the amount of debris was graded moderate or extensive. Predictors for moderate/extensive debris were moderate/severe aortic calcification (OR 1.50, CI 1.05-2.15, p = 0.03), pre- and postdilatation (OR 1.97, CI 1.02-3.79, p = 0.04 and OR 1.71, CI 1.01-2.89, p = 0.048). The risk of stroke was numerically lower in patients who underwent TAVR with the Sentinel CPS (2.1 vs. 5.1%, respectively, p = 0.15). There was no stroke during CPS deployment, but one patient had a stroke immediately after device retrieval.<br /><b>Conclusions</b><br />The Sentinel-CPS was successfully deployed in 85% of patients.

<div><h4>Culprit lesion plaque characterization and thrombus grading by high-definition intravascular ultrasound in patients with ST-segment elevation myocardial infarction.</h4><i>Groenland FTW, Ziedses des Plantes AC, Neleman T, Scoccia A, ... Van Mieghem NM, Daemen J</i><br /><b>Background</b><br />Dedicated prospective studies investigating high-definition intravascular ultrasound (HD-IVUS)-guided primary percutaneous coronary intervention (PCI) are lacking. The aim of this study was to qualify and quantify culprit lesion plaque characteristics and thrombus using HD-IVUS in patients presenting with ST-segment elevation myocardial infarction (STEMI).<br /><b>Methods</b><br />The SPECTRUM study is a prospective, single-center, observational cohort study investigating the impact of HD-IVUS-guided primary PCI in 200 STEMI patients (NCT05007535). The first 100 study patients with a de novo culprit lesion and a per-protocol mandated preintervention pullback directly after vessel wiring were subject to a predefined imaging analysis. Culprit lesion plaque characteristics and different thrombus types were assessed. An IVUS-derived thrombus score, including a 1-point adjudication for a long total thrombus length, long occlusive thrombus length, and large maximum thrombus angle, was developed to differentiate between low (0-1 points) and high (2-3 points) thrombus burden. Optimal cut-off values were obtained using receiver operating characteristic curves.<br /><b>Results</b><br />The mean age was 63.5 (±12.1) years and 69 (69.0%) patients were male. The median culprit lesion length was 33.5 (22.8-38.9) mm. Plaque rupture and convex calcium were appreciated in 48 (48.0%) and 10 (10.0%) patients, respectively. Thrombus was observed in 91 (91.0%) patients (acute thrombus 3.3%; subacute thrombus 100.0%; organized thrombus 22.0%). High IVUS-derived thrombus burden was present in 37/91 (40.7%) patients and was associated with higher rates of impaired final thrombolysis in myocardial infarction flow (grade 0-2) (27.0% vs. 1.9%, p &lt; 0.001).<br /><b>Conclusions</b><br />HD-IVUS in patients presenting with STEMI allows detailed culprit lesion plaque characterization and thrombus grading that may guide tailored PCI.<br /><br />© 2023 The Authors.

<div><h4>Clinical outcomes of transcatheter mitral valve replacement: two-year results of the CHOICE-MI Registry.</h4><i>Ludwig S, Perrin N, Coisne A, Ben Ali W, ... Modine T, Conradi L</i><br /><b>Background</b><br />Transcatheter mitral valve replacement (TMVR) using dedicated devices is an alternative therapy for high-risk patients with symptomatic mitral regurgitation (MR).<br /><b>Aims</b><br />This study aimed to assess the 2-year outcomes and predictors of mortality in patients undergoing TMVR from the multicentre CHOICE-MI Registry.<br /><b>Methods</b><br />The CHOICE-MI Registry included consecutive patients with symptomatic MR treated with 11 different dedicated TMVR devices at 31 international centres. The investigated endpoints included mortality and heart failure hospitalisation rates, procedural complications, residual MR, and functional status. Multivariable Cox regression analysis was applied to identify independent predictors of 2-year mortality.<br /><b>Results</b><br />A total of 400 patients, median age 76 years (interquartile range [IQR] 71, 81), 59.5% male, EuroSCORE II 6.2% (IQR 3.8, 12.0), underwent TMVR. Technical success was achieved in 95.2% of patients. MR reduction to ≤1+ was observed in 95.2% at discharge with durable results at 1 and 2 years. New York Heart Association Functional Class had improved significantly at 1 and 2 years. All-cause mortality was 9.2% at 30 days, 27.9% at 1 year and 38.1% at 2 years after TMVR. Chronic obstructive pulmonary disease, reduced glomerular filtration rate, and low serum albumin were independent predictors of 2-year mortality. Among the 30-day complications, left ventricular outflow tract obstruction, access site and bleeding complications showed the strongest impact on 2-year mortality.<br /><b>Conclusions</b><br />In this real-world registry of patients with symptomatic MR undergoing TMVR, treatment with TMVR was associated with a durable resolution of MR and significant functional improvement at 2 years. Two-year mortality was 38.1%. Optimised patient selection and improved access site management are mandatory to improve outcomes.<br /><br /><br /><br /><small>EuroIntervention: 26 May 2023; epub ahead of print</small></div>

<div><h4>Long-Term High Level of Insulin Resistance Is Associated With an Increased Prevalence of Coronary Artery Calcification: The CARDIA Study.</h4><i>Ke Z, Huang R, Xu X, Liu W, ... Zhuang X, Zhen L</i><br /><AbstractText><br /><b>Background:</b><br/>Coronary artery calcification (CAC) is a crucial indicator of subclinical atherosclerotic cardiovascular disease. The relationship between long-term insulin resistance (IR) trajectory and CAC has been explored in few studies. Therefore, this study aimed to investigate whether the long-term IR time series of young adults are associated with the incidence of CAC in midlife. Methods and Results In a cohort study comprising 2777 participants from the CARDIA (Coronary Artery Risk Development in Young Adults) study, the homeostasis model assessment for IR was used to measure IR levels, and group-based trajectory modeling was used to fit three 25-year homeostasis model assessments for IR trajectories. Logistic regression was used to estimate the association between the 3 homeostasis model assessments for IR trajectories and CAC events at year 25. The results showed that among 2777 participants (mean age, 50.10±3.58 years; 56.2% women; 46.4% Black), there were 780 incident CAC events after a 25-year follow-up. After full adjustment, the prevalence of CAC was higher in the moderate- (odds ratio [OR], 1.40 [1.10-1.76]) and the high-level homeostasis model assessments for IR trajectories (OR, 1.84 [1.21-2.78]) than in the low-level trajectory. This association was observed in obese individuals despite the negative interaction between IR and different types of obesity (all <i>P</i> interactions &gt;0.05). <br /><b>Conclusions:</b><br/>Our study revealed that young adults with a higher level of IR were more likely to develop CAC in middle age. Furthermore, this association persisted in obese individuals. These findings highlight the importance of identifying subclinical cardiovascular risk factors and implementing primary prevention measures.</AbstractText><br /><br /><br /><br /><small>J Am Heart Assoc: 23 May 2023:e028985; epub ahead of print</small></div>

Participants that completed the Rose Angina Questionnaire were included and categorised as angina or no angina. Subjects with a valid coronary CT angiography (CCTA) were categorised by degree of coronary atherosclerosis; ≥50% obstruction (obstructive coronary atherosclerosis), &lt;50% obstruction or any atheromatosis (non-obstructive coronary atherosclerosis) or none (no coronary atherosclerosis).<br /><b>Results</b><br />The study population consisted of 28 974 questionnaire responders (median age 57.4 years, female 51.6%, hypertension 19.9%, hyperlipidaemia 7.9%, diabetes mellitus 3.7%), of which 1025 (3.5%) fulfilled the criteria of angina. Coronary atherosclerosis was more common in individuals having angina compared with those with no angina (n=24 602, obstructive coronary atherosclerosis 11.8% vs 5.4%, non-obstructive coronary atherosclerosis 38.9% vs 37.0%, no coronary atherosclerosis 49.4% vs 57.7%, all p&lt;0.001). Factors independently associated with angina were birthplace outside of Sweden (OR 2.58 (95% CI 2.10 to 2.92)), low educational level (OR 1.41 (1.10 to 1.79)), unemployment (OR 1.51 (1.27 to 1.81)), poor economic status (OR 1.85 (1.38 to 2.47)), symptoms of depression (OR 1.63 (1.38 to 1.92)) and high degree of stress (OR 2.92 (1.80 to 4.73)).<br /><b>Conclusion</b><br />Angina pectoris symptoms are common (3.5%) among middle-aged individuals of the general population of Sweden, though with low association to obstructive coronary atherosclerosis.

<div><h4>Significance of Anteroseptal Late Gadolinium Enhancement Among Patients With Acute Myocarditis.</h4><i>Mulla W, Segev A, Novak A, Yogev D, ... Beigel R, Younis A</i><br /><AbstractText>Anteroseptal location of late gadolinium enhancement (LGE) in patients with acute myocarditis (AM) detected by cardiovascular magnetic resonance may indicate an independent marker of unfavorable outcomes according to recent data. We aimed to evaluate the clinical characteristics, management, and inhospital outcomes in patients with AM with positive LGE based on its presence in the anteroseptal location. We analyzed data from 262 consecutive patients hospitalized with a diagnosis of AM with positive LGE within 5 days of hospitalization (n = 425). Patients were divided into 2 groups: those with anteroseptal LGE (n = 25, 9.5%) and those with non-anteroseptal LGE (n = 237, 90.5%). Except for age that was higher in patients with anteroseptal LGE, the demographic and clinical characteristics did not differ significantly between both groups including past medical history, clinical presentation, electrocardiogram parameters, and lab values. Moreover, patients with anteroseptal LGE were more likely to present with reduced left ventricular ejection fraction and to receive congestive heart failure treatments. Although univariate analysis showed that patients with anteroseptal LGE were more likely to have inhospital major adverse cardiac events (28% vs 9%, p = 0.003), there was no difference inhospital outcomes on multivariable analysis between both groups (hazard ratio, 1.17 [95% confidence interval, 0.32 to 4.22], p = 0.81). A higher left ventricular ejection fraction in either echocardiography or cardiovascular magnetic resonance corresponded to better inhospital outcomes regardless of the presence or absence of anteroseptal LGE. In conclusion, the presence of anteroseptal LGE did not confer additional prognostic value for inhospital outcomes.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Implications of the Mitral Leaflet Coaptation Pattern on Clinical Outcomes in Patients With Functional Mitral Regurgitation.</h4><i>Kim H, Kim IC, Lee S</i><br /><AbstractText>The classification of secondary mitral regurgitation (MR) is based on atrial functional MR (AFMR) or ventricular functional MR (VFMR) and volume changes, but the mitral leaflet coaptation angle also contributes to the MR mechanism. The clinical implications of the coaptation angle on cardiovascular (CV) outcomes have not been well evaluated. A total of 469 consecutive patients (265 AFMR vs 204 VFMR) with more than moderate MR were evaluated for the occurrence of heart failure, mitral valve operations, and CV death. The coaptation angle was assessed by measuring the internal angle between both leaflets at mid-systole using the apical 3-chamber view. A coaptation angle ≥130° was classified as leaflet flattening, and an angle &lt;130° was classified as leaflet tethering. AFMR and VFMR were associated with higher frequencies of leaflet flattening and tethering, respectively. AFMR was more likely to be associated with older age, atrial fibrillation, and preserved ejection fraction, all of which were related to leaflet flattening. During a follow-up of 2.3 years, 83 patients had heart failure (17.7%), 21 patients underwent mitral valve operations (4.5%), and 34 patients died (7%). Compared with leaflet tethering, leaflet flattening was more significantly related to CV events, whereas CV event rates were less markedly different in A/VFMR. Irrespective of A/VFMR, leaflet flattening and atrial fibrillation were associated with a higher frequency of CV events. Adjusted analysis showed that leaflet flattening remained an independent predictor of CV events (hazard ratio 3.5, 95% confidence interval 1.11 to 4.88, p = 0.003), whereas A/VFMR did not. In conclusion, the leaflet coaptation angle in patients with functional MR could provide risk stratification superior to that of A/VFMR. Leaflet flattening appears to be associated with unfavorable clinical outcomes.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Do PCI Facility Openings and Closures Affect AMI Outcomes Differently in High- vs Average-Capacity Markets?</h4><i>Shen YC, Krumholz HM, Hsia RY</i><br /><b>Background</b><br />Disparities in access to percutaneous coronary intervention (PCI) for patients with acute myocardial infarction may result from openings and closures of PCI-providing hospitals, potentially leading to low hospital PCI volume, which is associated with poor outcomes.<br /><b>Objectives</b><br />The authors sought to determine whether openings and closures of PCI hospitals have differentially impacted patient health outcomes in high- vs average-capacity PCI markets.<br /><b>Methods</b><br />In this retrospective cohort study, the authors identified PCI hospital availability within a 15-minute driving time of zip code communities. The authors categorized communities by baseline PCI capacity and identified changes in outcomes associated with PCI-providing hospital openings and closures using community fixed-effects regression models.<br /><b>Results</b><br />From 2006 to 2017, 20% and 16% of patients in average- and high-capacity markets, respectively, experienced a PCI hospital opening within a 15-minute drive. In average-capacity markets, openings were associated with a 2.6 percentage point decrease in admission to a high-volume PCI facility; high-capacity markets saw an 11.6 percentage point decrease. After an opening, patients in average-capacity markets experienced a 5.5% and 7.6% relative increase in likelihood of same-day and in-hospital revascularization, respectively, as well as a 2.5% decrease in mortality. PCI hospital closures were associated with a 10.4% relative increase in admission to high-volume PCI hospitals and a 1.4 percentage point decrease in receipt of same-day PCI. There was no change observed in high-capacity PCI markets.<br /><b>Conclusions</b><br />After openings, patients in average-capacity markets derived significant benefits, whereas those in high-capacity markets did not. This suggests that past a certain threshold, facility opening does not improve access and health outcomes.<br /><br />Copyright © 2023 American College of Cardiology Foundation.

<div><h4>Effects of Elective Coronary Revascularization vs Medical Therapy Alone on Noncardiac Mortality: A Meta-Analysis.</h4><i>Navarese EP, Lansky AJ, Farkouh ME, Grzelakowska K, ... Wijns W, Kereiakes DJ</i><br /><b>Background</b><br />Uncertainty exists whether coronary revascularization plus medical therapy (MT) is associated with an increase in noncardiac mortality in chronic coronary syndrome (CCS) when compared with MT alone, particularly following recent data from the ISCHEMIA-EXTEND (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) trial.<br /><b>Objectives</b><br />This study conducted a large-scale meta-analysis of trials comparing elective coronary revascularization plus MT vs MT alone in patients with CCS to determine whether revascularization has a differential impact on noncardiac mortality at the longest follow-up.<br /><b>Methods</b><br />We searched for randomized trials comparing revascularization plus MT vs MT alone in patients with CCS. Treatment effects were measured by rate ratios (RRs) with 95% CIs, using random-effects models. Noncardiac mortality was the prespecified endpoint. The study is registered with PROSPERO (CRD42022380664).<br /><b>Results</b><br />Eighteen trials were included involving 16,908 patients randomized to either revascularization plus MT (n = 8,665) or to MT alone (n = 8,243). No significant differences were detected in noncardiac mortality between the assigned treatment groups (RR: 1.09; 95% CI: 0.94-1.26; P = 0.26), with absent heterogeneity (I<sup>2</sup> = 0%). Results were consistent without the ISCHEMIA trial (RR: 1.00; 95% CI: 0.84-1.18; P = 0.97). By meta-regression, follow-up duration did not affect noncardiac death rates with revascularization plus MT vs MT alone (P = 0.52). Trial sequential analysis confirmed the reliability of meta-analysis, with the cumulative Z-curve of trial evidence within the nonsignificance area and reaching futility boundaries. Bayesian meta-analysis findings were consistent with the standard approach (RR: 1.08; 95% credible interval: 0.90-1.31).<br /><b>Conclusions</b><br />In patients with CCS, noncardiac mortality in late follow-up was similar for revascularization plus MT compared with MT alone.<br /><br />Copyright © 2023 American College of Cardiology Foundation.

<div><h4>Impact of High Implantation of Transcatheter Aortic Valve on Subsequent Conduction Disturbances and Coronary Access.</h4><i>Ochiai T, Yamanaka F, Shishido K, Moriyama N, ... Makkar R, Saito S</i><br /><b>Background</b><br />Data regarding the impact of high transcatheter heart valve (THV) implantation on coronary access after transcatheter aortic valve replacement (TAVR) as assessed by postimplantation computed tomography (CT) are scarce.<br /><b>Objectives</b><br />The authors sought to assess the impact of high THV implantation on coronary access after TAVR.<br /><b>Methods</b><br />We included 160 and 258 patients treated with Evolut R/PRO/PRO+ and SAPIEN 3 THVs, respectively. In the Evolut R/PRO/PRO+ group, the target implantation depth was 1 to 3 mm using the cusp overlap view with commissural alignment technique for the high implantation technique (HIT), whereas it was 3 to 5 mm using 3-cusp coplanar view for the conventional implantation technique (CIT). In the SAPIEN 3 group, the HIT employed the radiolucent line-guided implantation, whereas the central balloon marker-guided implantation was used for the CIT. Post-TAVR CT was performed to analyze coronary accessibility.<br /><b>Results</b><br />HIT reduced the incidence of new conduction disturbances after TAVR for both THVs. In the Evolut R/PRO/PRO+ group, post-TAVR CT showed that the HIT group had a higher incidence of the interference of THV skirt (22.0% vs 9.1%; P = 0.03) and a lower incidence of the interference of THV commissural posts (26.0% vs 42.7%; P = 0.04) with access to 1 or both coronary ostia compared with the CIT group. These incidences were similar between the HIT and CIT groups in the SAPIEN 3 group (THV skirt: 0.9% vs 0.7%; P = 1.00; THV commissural tabs: 15.7% vs 15.3%; P = 0.93). In both THVs, CT-identified risk of sinus sequestration in TAVR-in-TAVR was significantly higher in the HIT group compared with the CIT group (Evolut R/PRO/PRO+ group: 64.0% vs 41.8%; P = 0.009; SAPIEN 3 group: 17.6% vs 5.3%; P = 0.002).<br /><b>Conclusions</b><br />High THV implantation substantially reduced conduction disturbances after TAVR. However, post-TAVR CT revealed that there is a risk for unfavorable future coronary access after TAVR and sinus sequestration in TAVR-in-TAVR.

Serra V, Pan M</i><br /><b>Background</b><br />Coronary obstruction (CO) following transcatheter aortic valve replacement (TAVR) is a life-threatening complication, scarcely studied.<br /><b>Objectives</b><br />The authors analyzed the incidence of CO after TAVR, presentation, management, and in-hospital and 1-year clinical outcomes in a large series of patients undergoing TAVR.<br /><b>Methods</b><br />Patients from the Spanish TAVI (Transcatheter Aortic Valve Implantation) registry who presented with CO in the procedure, during hospitalization or at follow-up were included. Computed tomography (CT) risk factors were assessed. In-hospital, 30-day, and 1-year all-cause mortality rates were analyzed and compared with patients without CO using logistic regression models in the overall cohort and in a propensity score-matched cohort.<br /><b>Results</b><br />Of 13,675 patients undergoing TAVR, 115 (0.80%) presented with a CO, mainly during the procedure (83.5%). The incidence of CO was stable throughout the study period (2009-2021), with a median annual rate of 0.8% (range 0.3%-1.3%). Preimplantation CT scans were available in 105 patients (91.3%). A combination of at least 2 CT-based risk factors was less frequent in native than in valve-in-valve patients (31.7% vs 78.3%; P &lt; 0.01). Percutaneous coronary intervention was the treatment of choice in 100 patients (86.9%), with a technical success of 78.0%. In-hospital, 30-day, and 1-year mortality rates were higher in CO patients than in those without CO (37.4% vs 4.1%, 38.3% vs 4.3%, and 39.1% vs 9.1%, respectively; P &lt; 0.001).<br /><b>Conclusions</b><br />In this large, nationwide TAVR registry, CO was a rare, but often fatal, complication that did not decrease over time.

<div><h4>Myocardial Injury After Transcatheter Aortic Valve Replacement According to VARC-3 Criteria.</h4><i>Real C, Avvedimento M, Nuche J, Franzone A, ... Esposito G, Rodés-Cabau J</i><br /><b>Background</b><br />The Valve Academic Research Consortium (VARC)-3 definition for myocardial injury after transcatheter aortic valve replacement (TAVR) lacks of clinical validation.<br /><b>Objectives</b><br />This study sought to determine the incidence, predictors, and clinical impact of periprocedural myocardial injury (PPMI) following TAVR as defined by recent VARC-3 criteria.<br /><b>Methods</b><br />We included 1,394 consecutive patients who underwent TAVR with a new-generation transcatheter heart valve. High-sensitivity troponin levels were assessed at baseline and within 24 hours after the procedure. PPMI was defined according to VARC-3 criteria as an increase ≥70 times in troponin levels (vs ≥15 times according to the VARC-2 definition). Baseline, procedural, and follow-up data were prospectively collected.<br /><b>Results</b><br />PPMI was diagnosed in 193 (14.0%) patients. Female sex and peripheral artery disease were independent predictors of PPMI (P &lt; 0.01 for both). PPMI was associated with a higher risk of mortality at 30-day (HR: 2.69, 95% CI: 1.50-4.82; P = 0.001) and 1-year (for all-cause mortality, HR: 1.54; 95% CI: 1.04-2.27; P = 0.032; for cardiovascular mortality, HR: 3.04; 95% CI: 1.68-5.50; P &lt; 0.001) follow-up. PPMI according to VARC-2 criteria had no impact on mortality.<br /><b>Conclusions</b><br />About 1 out of 10 patients undergoing TAVR in the contemporary era had PPMI as defined by recent VARC-3 criteria, and baseline factors like female sex and peripheral artery disease determined an increased risk. PPMI had a negative impact on early and late survival.

Tang GHL, CUTTING-EDGE Investigators</i><br /><b>Background</b><br />Although &gt;150,000 mitral TEER procedures have been performed worldwide, the impact of MR etiology on MV surgery after TEER remains unknown.<br /><b>Objectives</b><br />The authors sought to compare outcomes of mitral valve (MV) surgery after failed transcatheter edge-to-edge repair (TEER) stratified by mitral regurgitation (MR) etiology.<br /><b>Methods</b><br />Data from the CUTTING-EDGE registry were retrospectively analyzed. Surgeries were stratified by MR etiology: primary (PMR) and secondary (SMR). MVARC (Mitral Valve Academic Research Consortium) outcomes at 30 days and 1 year were evaluated. Median follow-up was 9.1 months (IQR: 1.1-25.8 months) after surgery.<br /><b>Results</b><br />From July 2009 to July 2020, 330 patients underwent MV surgery after TEER, of which 47% had PMR and 53.0% had SMR. Mean age was 73.8 ± 10.1 years, median STS risk at initial TEER was 4.0% (IQR: 2.2%-7.3%). Compared with PMR, SMR had a higher EuroSCORE, more comorbidities, lower LVEF pre-TEER and presurgery (all P &lt; 0.05). SMR patients had more aborted TEER (25.7% vs 16.3%; P = 0.043), more surgery for mitral stenosis after TEER (19.4% vs 9.0%; P = 0.008), and fewer MV repairs (4.0% vs 11.0%; P = 0.019). Thirty-day mortality was numerically higher in SMR (20.4% vs 12.7%; P = 0.072), with an observed-to-expected ratio of 3.6 (95% CI: 1.9-5.3) overall, 2.6 (95% CI: 1.2-4.0) in PMR, and 4.6 (95% CI: 2.6-6.6) in SMR. SMR had significantly higher 1-year mortality (38.3% vs 23.2%; P = 0.019). On Kaplan-Meier analysis, the actuarial estimates of cumulative survival were significantly lower in SMR at 1 and 3 years.<br /><b>Conclusions</b><br />The risk of MV surgery after TEER is nontrivial, with higher mortality after surgery, especially in SMR patients.

Pre-PCI OCT was used to assess calcium burden and post-PCI OCT was used to assess absolute and relative stent expansion.<br /><b>Results</b><br />A total of 361 lesions in 336 patients were analyzed. Target lesion calcification (defined as OCT-detected maximum calcium angle ≥ 30°) was present in 242 (67.0%) lesions. Following PCI, median MSA was 5.37 mm<sup>2</sup> in calcified lesions and 6.24 mm<sup>2</sup> in noncalcified lesions (p &lt; 0.001). Median stent expansion was 78% in calcified lesions and 83% in noncalcified lesions (p = 0.325). In the subset of calcified lesions, average stent diameter, preprocedural minimal lumen area, and total calcium length were independent predictors of MSA in multivariable analysis (mean difference 2.69 mm<sup>2</sup> /mm<sup>2</sup> , 0.52 mm<sup>2</sup> /mm, and -0.28 mm<sup>2</sup> /5 mm, respectively, all p &lt; 0.001). Total stent length was the only independent predictor of relative stent expansion (mean difference -0.465% per mm, p &lt; 0.001). Calcium angle, thickness, and the presence of nodular calcification were not significantly associated with MSA or stent expansion in multivariable analyses.<br /><b>Conclusion</b><br />Calcium length appeared to be the most important OCT-derived predictor of MSA, whereas stent expansion was mainly determined by total stent length.<br /><br />© 2023 The Authors.

<div><h4>Percutaneous treatment of left circumflex coronary artery injury related to mitral valve surgery: Case series and systematic review of the literature.</h4><i>Benedetti A, Castaldi G, Poletti E, Moroni A, ... Agostoni P, Zivelonghi C</i><br /><AbstractText>Left circumflex coronary artery (LCx) injury related to mitral valve surgery is a rare complication. The best treatment option is not defined, and percutaneous coronary intervention (PCI) may represent an effective treatment to avoid prolonged myocardial ischemia. To evaluate feasibility and efficacy of PCI treatment, all records of LCx injury related to mitral valve surgery and treated with PCI were included after a systematic PubMed searching. Moreover, we retrospectively analyzed our single-center PCI database and patients fulfilling the inclusion criteria were included. Patients undergoing transcatheter mitral valve intervention, non-mitral valve surgery, conservatively or surgically treated after LCx injury were excluded. Data about patient characteristics, procedural details, PCI success, and in-hospital mortality were collected. Fifty-six patients were included, 58.9% were male (n = 33) and the median age was 60.5 years (IQR = 21.75). The majority had left dominant or codominant coronary system (62.2%, n = 28 and 15.6%, n = 7, respectively). Clinical manifestations ranged from hemodynamic stability (21.1%, n = 8) to hemodynamic instability (42.1%, n = 16) and cardiac arrest (18.4%, n = 7). On ECG, 23.5% of patients (n = 12) presented ST-segment depression, 58.8% (n = 30) ST-segment elevation, 7.8% (n = 4) atrioventricular block, and 29.4% (n = 15) ventricular arrhythmias. Left ventricle dysfunction was present in 52.3% (n = 22) of patients and wall motion abnormalities in 71.4% (n = 30). PCI success rate was 82.1% (n = 46) and in-hospital mortality 4.5% (n = 2). LCx injury related to mitral surgery is a rare complication characterized by an increased risk of mortality. PCI seems a feasible treatment option, still burdened by suboptimal results, probably related to the technical challenges posed by the surgical failure.</AbstractText><br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 20 May 2023; epub ahead of print</small></div>

Nozato T, Ashikaga T</i><br /><b>Background</b><br />Percutaneous coronary intervention (PCI) for calcified coronary artery remains challenging in the drug-eluting stent (DES) era. While recent studies reported the efficacy of orbital atherectomy (OA) combined with DES for calcified lesion, the effectiveness of drug-coated balloon (DCB) following OA has not been fully elucidated.<br /><b>Methods</b><br />Between June 2018 and June 2021, 135 patients who received PCI for calcified de novo coronary lesions with OA were enrolled and divided into two groups; OA followed by DCB (n = 43) if the target lesion achieved acceptable preparation, or second- or third-generation DESs (n = 92) if the target lesion showed suboptimal preparation between June 2018 and June 2021. All patients underwent PCI with optical coherence tomography (OCT) imaging. The primary endpoint was 1-year major adverse cardiac event (MACE), that was a composite of cardiac death, nonfatal myocardial infarction, or target lesion revascularization.<br /><b>Results</b><br />Mean age was 73 years and 82% was male. In OCT analysis, maximum calcium plaque was thicker (median: 1050 µm [interquartile range (IQR): 945-1175 µm] vs. 960 µm [808-1100 µm], p = 0.017), calcification arc tended to larger (median: 265° [IQR: 209-360°] vs. 222° [162-305°], p = 0.058) in patients with DCB than in DES, and the postprocedure minimum lumen area was smaller in DCB compared with minimum stent area in DES (median: 3.83 mm<sup>2</sup> [IQR: 3.30-4.52 mm<sup>2</sup> ] vs. 4.86 mm<sup>2</sup> [4.05-5.82 mm<sup>2</sup> ], p &lt; 0.001). However, 1 year MACE free rate was not significantly different between 2 groups (90.3% in DCB vs. 96.6% in DES, log-rank p = 0.136). In the subgroup analysis of 14 patients who underwent follow-up OCT imaging, late lumen area loss was lower in patients with DCB than DES, despite lower lesion expansion rate in DCB than DES.<br /><b>Conclusions</b><br />In calcified coronary artery disease, DCB alone strategy (if acceptable lesion preparation was performed with OA) was feasible compared with DES following OA with respect to 1-year clinical outcomes. Our finding indicated using DCB with OA might be reduce late lumen area loss for severe calcified lesion.<br /><br />© 2023 The Authors.

Transesophageal echocardiogram did not reveal any vegetations, as the metallic stent frames caused significant artifacts. Position emission tomography was also negative. Intracardiac echocardiogram (ICE) was performed retrogradely through the ascending aorta, which showed clear vegetations over the stent frame of the transcatheter heart valve. Endocarditis after transcatheter aortic valve implantation was not uncommon. With increasing use of valve-in-valve procedures, echocardiographic diagnosis of IE would be more challenging. This case demonstrated the advantage of ICE over conventional echocardiography in visualizing the neo-aortic valve complex for diagnosing IE.</AbstractText><br /><br />© 2023 The Authors.

<div><h4>What do we mean by complex percutaneous coronary intervention? An assessment of agreement amongst interventional cardiologists for defining complexity.</h4><i>Rjoob K, McGilligan V, McAllister R, Bond R, ... Peace A, EAPCI Innovation and Digital Cardiology Committee</i><br /><b>Background</b><br />In the last decade, percutaneous coronary intervention (PCI) has evolved toward the treatment of complex disease in patients with multiple comorbidities. Whilst there are several definitions of complexity, it is unclear whether there is agreement between cardiologists in classifying complexity of cases. Inconsistent identification of complex PCI can lead to significant variation in clinical decision-making.<br /><b>Aim</b><br />This study aimed to determine the inter-rater agreement in rating the complexity and risk of PCI procedures.<br /><b>Method</b><br />An online survey was designed and disseminated amongst interventional cardiologists by the European Association of Percutaneous Cardiovascular Intervention (EAPCI) board. The survey presented four patient vignettes, with study participants assessing these cases to classify their complexity.<br /><b>Results</b><br />From 215 respondents, there was poor inter-rater agreement in classifying the complexity level (k = 0.1) and a fair agreement (k = 0.31) in classifying the risk level. The experience level of participants did not show any significant impact on the inter-rater agreement of rating the complexity level and the risk level. There was good level of agreement between participants in terms of rating 26 factors for classifying complex PCI. The top five factors were (1) impaired left ventricular function, (2) concomitant severe aortic stenosis, (3) last remaining vessel PCI, (4) requirement fort calcium modification and (5) significant renal impairment.<br /><b>Conclusion</b><br />Agreement among cardiologists in classifying complexity of PCI is poor, which may lead to suboptimal clinical decision-making, procedural planning as well as long-term management. Consensus is needed to define complex PCI, and this requires clear criteria incorporating both lesion and patient characteristics.<br /><br />© 2023 The Authors.

<div><h4>Poorer Survival after Out-of-Hospital Cardiac Arrest among Cancer Patients - A Population-Based Register Study.</h4><i>Hägglund HL, Jonsson M, Hedayati E, Hedman C, Djärv T</i><br /><b>Background:</b><br/>and aims</b><br />The association between cancer and survival after out-of-hospital cardiac arrest (OHCA) has not been thoroughly investigated. We aimed to address this knowledge gap using national, population-based registries.<br /><b>Methods</b><br />For this study, 30,163 OHCA patients (≥18 years) were included from the Swedish Register of Cardiopulmonary Resuscitation. Via linkage to the National Patient Registry, 2,894 patients (10%) with cancer diagnosed within 5 years prior to OHCA were identified. Differences in 30-day survival between cancer patients and controls (defined as OHCA patients without previous cancer diagnosis) were assessed related to cancer stage (locoregional vs metastasized cancer) and cancer site (i.e. lung cancer, breast cancer etc.) using logistic regression adjusted for prognostic factors. Long-term survival is presented as a Kaplan-Meier curve.<br /><b>Results</b><br />For locoregional cancer no statistically significant difference in return of spontaneous circulation (ROSC) was seen compared to controls, metastasized disease was associated with poorer chance of ROSC. Cancer was associated with lower 30-day survival for all cancers (Adjusted odds ratio, OR, 0.57, CI 0.49-0.66), locoregional cancer (Adjusted OR 0.68, CI 0.57-0.82) and metastasized cancer (Adjusted OR 0.24, CI 0.14-0.40) compared to controls. Lower 30-day survival compared to controls was seen for lung cancer, gynaecological and haematological cancers.<br /><b>Conclusion</b><br />Cancer is associated with poorer 30-day survival after OHCA. This study suggests that cancer site and disease stage are more relevant factors than cancer in general with regard to its effect on survival after OHCA.<br /><br />© The Author(s) 2023.

<div><h4>Eligibility to Intensified Antithrombotic Regimens for Secondary Prevention in Patients Who Underwent Percutaneous Coronary Intervention.</h4><i>Greco A, Scilletta S, Faro DC, Agnello F, ... Imbesi A, Capodanno D</i><br /><AbstractText>Single antiplatelet therapy (SAPT) and intensified antithrombotic regimens (prolonged dual antiplatelet therapy [DAPT] or dual pathway inhibition [DPI]) are recommended for secondary prevention in patients who underwent percutaneous coronary intervention (PCI) after initial DAPT. We aimed to characterize eligibility to such strategies and to explore to what extent guidelines are applied in clinical practice. Patients who underwent PCI for acute or chronic coronary syndrome who completed initial DAPT were analyzed from a prospective registry. Patients were categorized into SAPT, prolonged DAPT/DPI, or DPI groups as per guideline indication by using a risk stratification algorithm. Predictors of receiving intensified regimens and the divergency of practice from guidelines were investigated. Between October 2019 and September 2021, a total of 819 patients were included. Based on the guidelines, 83.7% of patients qualified for SAPT, 9.6% for any intensified regimen (i.e., prolonged DAPT or DPI), and 6.7% for DPI only. At multivariable analysis, patients were more likely to receive an intensified regimen if they had diabetes, dyslipidemia, peripheral artery disease, multivessel disease, or previous myocardial infarction. Conversely, they were less likely to receive an intensified regimen if they had atrial fibrillation, chronic kidney disease, or previous stroke. Guidelines were not followed in 18.3% of cases. In particular, only 14.3% of candidates to intensified regimens were treated accordingly. In conclusion, although the majority of patients who underwent PCI after the initial period of DAPT were eligible for SAPT, 1 out of 6 had an indication to intensified regimens. However, such intensified regimens were underused among eligible patients.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

De Bruyne B, TIDES-ACS Study Group</i><br /><b>Importance</b><br />Titanium-nitride-oxide (TiNO)-coated stents show faster strut coverage compared with drug-eluting stents without excessive intimal-hyperplasia observed in bare metal stents. It is important to study long-term clinical outcomes after treatment of patients with an acute coronary syndrome (ACS) by TiNO-coated stents, which are neither drug-eluting stents nor bare metal stents.<br /><b>Objective</b><br />To compare the rate of main composite outcome of cardiac death, myocardial infarction (MI), or ischemia-driven target lesion revascularization at 5 years in patients with ACS randomized to receive either a TiNO-coated stent or a third-generation everolimus-eluting stent (EES).<br /><b>Design, setting, and participants</b><br />This multicenter, randomized, controlled, open-label trial was conducted in 12 clinical sites in 5 European countries and enrolled patients from January 2014 to August 2016. Patients presenting with ACS (ST-segment elevation MI, non-ST-segment elevation MI, and unstable angina) with at least 1 de novo lesion were randomized to receive either a TiNO-coated stent or an EES. The present report analyzes the long-term follow-up for the main composite outcome and its individual components. Analysis took place between November 2022 to March 2023.<br /><b>Main outcome</b><br />The primary end point was a composite of cardiac death, MI, or target lesion revascularization at 12-month follow-up.<br /><b>Results</b><br />A total of 1491 patients with ACS were randomly assigned to receive either TiNO-coated stents (989 [66.3%]) or EES (502 [33.7%]). The mean (SD) age was 62.7 (10.8) years, and 363 (24.3%) were female. At 5 years, the main composite outcome events occurred in 111 patients (11.2%) in the TiNO group vs 60 patients (12%) in the EES group (hazard ratio [HR], 0.94; 95% CI, 0.69-1.28; P = .69). The rate of cardiac death was 0.9% (9 of 989) vs 3.0% (15 of 502) (HR, 0.30; 95% CI, 0.13-0.69; P = .005), the rate of MI was 4.6% (45 of 989) vs 7.0% (35 of 502) (HR, 0.64; 95% CI, 0.41-0.99; P = .049), the rate of stent thrombosis was 1.2% (12 of 989) vs 2.8% (14 of 502) (HR, 0.43; 95% CI, 0.20-0.93; P = .034), and the rate of target lesion revascularization was 7.4% (73 of 989) vs 6.4% (32 of 502) (HR, 1.16; 95% CI, 0.77-1.76; P = .47) in the TiNO-coated stent arm and in the EES arm, respectively.<br /><br /><b>Conclusion:</b><br/>and relevance</b><br />In this study, patients with ACS had a main composite outcome that was not different 5 years after TiNO-coated stent or EES.<br /><b>Trial registration</b><br />ClinicalTrials.gov Identifier: NCT02049229.<br /><br /><br /><br /><small>JAMA Cardiol: 19 May 2023; epub ahead of print</small></div>

<div><h4>Management strategies for heavily calcified coronary stenoses: an EAPCI clinical consensus statement in collaboration with the EURO4C-PCR group.</h4><i>Barbato E, Gallinoro E, Abdel-Wahab M, Andreini D, ... Wijns W, Ribichini F</i><br /><AbstractText>Since the publication of the 2015 EAPCI consensus on rotational atherectomy, the number of percutaneous coronary interventions (PCI) performed in patients with severely calcified coronary artery disease has grown substantially. This has been prompted on one side by the clinical demand for the continuous increase in life expectancy, the sustained expansion of the primary PCI networks worldwide and the routine performance of revascularization procedures in elderly patients; on the other side, the availability of new and dedicated technologies such as orbital atherectomy and intravascular lithotripsy, as well as the optimization of the rotational atherectomy system, have increased operators\' confidence in attempting more challenging PCI. This current EAPCI clinical consensus statement prepared in collaboration with the EURO4C-PCR group describes the comprehensive management of patients with heavily calcified coronary stenoses, starting with how to use non-invasive and invasive imaging to assess calcium burden and inform procedural planning. Objective and practical guidance is provided on the selection of the optimal interventional tool and technique based on the specific calcium morphology and anatomic location. Finally, the specific clinical implications of treating these patients are considered, including the prevention and management of complications, and the importance of adequate training and education.</AbstractText><br /><br />© The Author(s) 2023.

<div><h4>Precipitating factors in patients with spontaneous coronary artery dissection: Clinical, laboratoristic and prognostic implications.</h4><i>Gurgoglione FL, Rizzello D, Giacalone R, Ferretti M, ... Niccoli G, Solinas E</i><br /><b>Background</b><br />Spontaneous coronary artery dissection (SCAD) often presents with acute coronary syndrome and underlying pathophysiology involves the interplay between predisposing factors and precipitating stressors, such as emotional and physical triggers. In our study we sought to compare clinical, angiographic and prognostic features in a cohort of patients with SCAD according to the presence and type of precipitating stressors.<br /><b>Methods</b><br />Consecutive patients with angiographic evidence of SCAD were divided into three groups: patients with emotional stressors, patients with physical stressors and those without any stressor. Clinical, laboratoristic and angiographic features were collected for each patient. The incidence of major adverse cardiovascular events, recurrent SCAD and recurrent angina was assessed at follow-up.<br /><b>Results</b><br />Among the total population (64 subjects), 41 [64.0%] patients presented with precipitating stressors, including emotional triggers (31 [48.4%] subjects) and physical efforts (10 [15.6%] subjects). As compared with the other groups, patients with emotional triggers were more frequently female (p = 0.009), had a lower prevalence of hypertension (p = 0.039] and dyslipidemia (p = 0.039), were more likely to suffer from chronic stress (p = 0.022) and presented with higher levels of C-reactive protein (p = 0.037) and circulating eosinophils cells (p = 0.012). At a median follow-up of 21 [7; 44] months, patients with emotional stressors experienced higher prevalence of recurrent angina (p = 0.025), as compared to the other groups.<br /><b>Conclusions</b><br />Our study shows that emotional stressors leading to SCAD may identify a SCAD subtype with specific features and a trend towards a worse clinical outcome.<br /><br />Copyright © 2023 Elsevier Ireland Ltd.

<div><h4>Pericardial Effusions: Perspective of the Acute Cardiac Care Physician.</h4><i>Jain CC, Reddy YNV</i><br /><AbstractText>Pericardial effusions can result in acute hemodynamic compromise and require rapid intervention. Understanding pericardial restraint is essential to determine the approach to newly identified pericardial effusions in the intensive care unit. As pericardial effusions stretch the pericardium, pericardial compliance reserve is eventually exhausted, with an exponential rise in compressive pericardial pressure. The severity of pericardial pressure increase depends on both the rapidity and volume of pericardial fluid accumulation. This increase in pericardial pressure is reflected in an increase in measured left and right sided \'filling\' pressures, but paradoxically left ventricular end diastolic volume (the true left ventricular preload) is decreased. This uncoupling of filling pressures and preload is the hallmark of pericardial restraint. When this occurs acutely from a pericardial effusion, rapid recognition and pericardiocentesis can be lifesaving. In this review, we will discuss the hemodynamics and pathophysiology of acute pericardial effusions, provide a physiological guide to determine need for pericardiocentesis in acute care, and discuss important caveats to management.</AbstractText><br /><br />© The Author(s) 2023.

Dumonteil N, Van Mieghem NM</i><br /><b>Background</b><br />Prospective data about transcatheter aortic valve implantation (TAVI) in bicuspid aortic valve (BAV) patients are limited.<br /><b>Aims</b><br />We aimed to evaluate the clinical impact of the Evolut PRO and R (34 mm) self-expanding prostheses in BAV patients and explore the impact of different computed tomography (CT) sizing algorithms in a prospective registry.<br /><b>Methods</b><br />A total of 149 bicuspid patients were treated in 14 countries. The primary endpoint was the intended valve performance at 30 days. Secondary endpoints were 30-day and 1-year mortality, severe patient-prosthesis mismatch (PPM) and the ellipticity index at 30 days. All study endpoints were adjudicated according to Valve Academic Research Consortium 3 criteria.<br /><b>Results</b><br />The mean Society of Thoracic Surgeons score was 2.6% (1.7-4.2) Type I L-R BAV was observed in 72.5% of the patients. Evolut valve sizes 29 and 34 mm were utilised in 49.0% and 36.9% of the cases, respectively. The 30-day cardiac death rate was 2.6%; the 1-year cardiac death rate was 11.0%. Valve performance at 30 days was observed in 142/149 (95.3%) patients. The mean aortic valve area post-TAVI was 2.1 (1.8-2.6) cm<sup>2</sup>, and the mean aortic gradient was 7.2 (5.4-9.5) mmHg. No patient had more than moderate aortic regurgitation at 30 days. PPM was observed in 13/143 (9.1%) surviving patients and was severe in 2 patients (1.6%). Valve function was maintained at 1 year. The mean ellipticity index remained 1.3 (interquartile range 1.2-1.4). Overall, 30-day and 1-year clinical and echocardiography outcomes were similar between the two sizing strategies.<br /><b>Conclusions</b><br />BIVOLUTX demonstrated a favourable bioprosthetic valve performance and good clinical outcomes after TAVI with the Evolut platform in patients with bicuspid aortic stenosis.

<div><h4>Impact of prophylactic intra-aortic balloon pump on early outcomes in patients with severe left ventricular dysfunction undergoing elective coronary artery bypass grafting with cardiopulmonary bypass.</h4><i>Kralev A, Kalisnik JM, Bauer A, Sirch J, Fittkau M, Fischlein T</i><br /><b>Objective</b><br />Our aim was to analyse whether prophylactic preoperative intraaortic balloon pump (IABP) improves outcomes in hemodynamically stable patients with low left ventricular ejection fraction (LVEF ≤30%) undergoing elective myocardial revascularization (CABG) using cardiopulmonary bypass (CPB). Secondary aim was to identify the predictors for low cardiac output syndrome (LCOS).<br /><b>Methods</b><br />Prospectively collected data of 207 consecutive patients with LVEF ≤30% undergoing elective isolated CABG with CPB from 01/2009 to 12/2019, 136 with and 71 patients without IABP, were retrieved retrospectively. Patients with prophylactic IABP were matched 1:1 with patients without IABP by a propensity score matching. Stepwise logistic regression was conducted to identify predictors of postoperative LCOS in the propensity-matched cohort. P value ≤0.05 was considered significant.<br /><b>Results</b><br />Reduced postoperative LCOS (9.9% vs. 26.8%, P = 0.017) was observed in patients receiving prophylactic IABP. Stepwise logistic regression identified preoperative IABP as preventive factor for postoperative LCOS [Odds Ratio (OR) 0.19,95% Confidence Interval (CI), 0.06-0.55, P = 0.004]. The need of vasoactive and inotropic support was lower in patients with prophylactic IABP at 24, 48 and 72 h after surgery (12.3 [8.2-18.6] vs. 22.2 [14.4-28.8], P &lt; 0.001, 7.7 [3.3-12.3] vs.16.3 [8.9-27.8], P &lt; 0.001 and 2.4 [0-7] vs. 11.5 [3.1-26], P &lt; 0.001, respectively). The patients in both groups did not differ in terms of in-hospital mortality (7.0% vs. 9.9%, P = 0.763).

Coronary microvascular and epicardial spasm, respectively, were diagnosed based on COVADIS criteria.<br /><b>Results</b><br />Patients were 63 ± 13 years old, predominantly female (69%) and had preserved LV ejection fraction (64 ± 8%). Overall, assessment of CBF and CR during ACh testing revealed a decrease in CBF of 0.62 (0.17-1.53)-fold and an increase of CR of 1.45 [0.67-4.02]-fold in spasm patients compared to 2.08 (1.73-4.76) for CBF and 0.45 (0.44-0.63) for CR in patients without coronary spasm (both p &lt; 0.01). Receiver operating characteristic revealed a high diagnostic ability of CBF and CR (AUC 0.86, p &lt; 0.001, respectively) in identifying patients with coronary spasm. However, in 21% of patients with epicardial spasm and 42% of patients with microvascular spasm a paradoxical response was observed.<br /><b>Conclusions</b><br />This study demonstrates feasibility and potential diagnostic value of intracoronary physiology assessments during ACh testing. We observed opposite responses of CBF and CR to ACh in patients with positive vs. negative spasm test.

Rotevatn S, McEntegart MB</i><br /><b>Background</b><br />The anatomical complexity of a chronic total occlusion (CTO) correlates with procedural failure and complication rates. CTO modification after unsuccessful crossing has been associated with subsequent higher technical success rates, but complication rates remain high with this approach. While successful CTO percutaneous coronary intervention (PCI) has been associated with improved angina and quality of life (QOL) this has not been demonstrated in anatomically high-risk CTOs. Whether a planned CTO modification procedure, hereafter named Investment procedure, could improve patient outcomes has never been investigated.<br /><b>Study design</b><br />Invest-CTO is a prospective, single-arm, international, multicenter study, evaluating the effectiveness and safety of a planned investment procedure, with a subsequent completion CTO PCI (at 8-12 weeks), in anatomically high-risk CTOs. We will enroll 200 patients with CTOs defined as high-risk according to our Invest CTO criteria at centers in Norway and United Kingdom. Patients with aorto-ostial lesions, occlusion within a previous stent, or a prior attempt at target vessel CTO PCI within 6 months will be excluded. The co-primary endpoints are cumulative procedural success (%) after both procedures, and a composite safety endpoint at 30 days after completion CTO PCI. Patient reported outcomes (PROs), treatment satisfaction, and clinical endpoints will be reported.<br /><b>Conclusion</b><br />This study will prospectively evaluate the effectiveness and safety of a planned two staged PCI procedure in the treatment of high-risk CTOs and may have the potential to change current clinical practice.<br /><br />© 2023 The Authors.

The aim of this study was to compare QFR with the established invasive measurements of coronary blood flow using instantaneous wave-free ratio (iFR) or resting full-cycle ratio (RFR) in daily cathlab routine.<br /><b>Methods</b><br />102 patients with stable coronary artery disease and a coronary stenosis of 40%-90% were simultaneously assessed with QFR and iFR or RFR. QFR-computation was performed by two certified experts using the appropriate software (QAngio XA 3D 3.2).<br /><b>Results</b><br />QFR showed a significant correlation (r = 0.75, p &lt; 0.001) to iFR and RFR. The area under the receiver curve for all measurements was 0.93 (95% confidence interval, 0.87-0.98) for QFR compared to iFR or RFR. QFR based assessment required less time with a median of 501 s (IQR 421-659 s) compared to iFR or RFR which required a median of 734 s to obtain the result (IQR 512-967 s; p &lt; 0.001). The median use of contrast medium was similar with 21 mL (IQR 16-30 mL) for the QFR-based and 22 mL (IQR 15-35 mL) for the iFR- or RFR-based diagnostic. QFR diagnostic required less radiation. The median dose area product for QFR was 307cGycm<sup>2</sup> (IQR 151-429 cGycm<sup>2</sup> ) compared to 599 cGycm<sup>2</sup> (IQR 345-1082 cGycm<sup>2</sup> ) for iFR or RFR, p &lt; 0.001.<br /><b>Conclusion</b><br />QFR measurements of coronary artery blood flow correlate with iFR or RFR measurements and are associated with shorter procedure times and reduced radiation dose.<br /><br />© 2023 The Authors.

Sasano T, Kakuta T</i><br /><AbstractText><br /><b>Background:</b><br/>A previous coronary computed tomography (CT) angiographic study failed to discriminate optical coherence tomography-defined intact fibrous cap culprit lesions (IFC group) from those with ruptured fibrous caps (RFC group) in patients with coronary artery disease. This study aimed to evaluate the diagnostic efficacy of preprocedural coronary CT imaging in identifying subsequently performed optical coherence tomography-defined plaque rupture or erosion at culprit lesions in patients with non-ST-segment-elevation acute myocardial infarction. Methods and Results This study used data from 2 recently published studies that tested the hypothesis that coronary CT angiography (CCTA) before percutaneous coronary intervention may provide diagnostic information on the high-risk atherosclerotic burden in patients with non-ST-segment-elevation acute myocardial infarction. In the analysis of 186 patients, optical coherence tomography identified 106 RFC plaques and 80 IFC plaques as the culprit lesions. On CT, the prevalence of low-attenuation plaque, positive remodeling, napkin-ring sign, and spotty calcification were all significantly lower in the IFC group. The culprit vessel pericoronary adipose tissue inflammation and coronary artery calcium scores were significantly lower in the IFC group than in the RFC group. The absence of low-attenuation plaque, napkin-ring sign, zero coronary artery calcium, and low pericoronary adipose tissue inflammation were independent predictors of IFC. When stratified into 5 subgroups according to the number of these 4 CT factors, the prevalence of IFC was 8.3%, 20.8%, 44.6%, 75.6%, and 100% (<i>P</i>&lt;0.001), respectively. <br /><b>Conclusions:</b><br/>Preprocedural comprehensive coronary CT imaging, including coronary artery calcium and pericoronary adipose tissue inflammation assessment, can accurately and noninvasively identify optical coherence tomography-defined IFC or RFC culprit lesions.</AbstractText><br /><br /><br /><br /><small>J Am Heart Assoc: 16 May 2023; 12:e029239</small></div>

<div><h4>Anemia and periprocedural complications determine contrast-associated acute kidney injury after recanalization of chronic coronary occlusions in chronic kidney disease.</h4><i>Werner GS, Lorenz S, Dimitriadis Z, Krueger B</i><br /><b>Background</b><br />Contrast-associated acute kidney injury (CA-AKI) is a potential risk associated with the percutaneous coronary interventions (PCI) for chronic total coronary occlusions (CTO) particularly with pre-existing chronic kidney disease (CKD). The determinants of CA-AKI in patients with pre-existing CKD in an era of advanced strategies of CTO recanalization techniques need to be considered for a risk evaluation of the procedure.<br /><b>Methods</b><br />A consecutive cohort of 2504 recanalization procedures for a CTO between 2013 and 2022 was analyzed. Of these, 514 (20.5%) were done in patients with CKD (estimated glomerular filtration rate &lt; 60 ml/min based on the most recently used CKD Epidemiology Collaboration equation).<br /><b>Results</b><br />The rate of patients classified to have CKD would be lower with 14.2% using the Cockcroft-Gault equation, and 18.1% using the modified Modification of Diet in Renal Disease equation. The technical success was high with 94.9% and 96.8% (p = 0.04) between patients with and without CKD. The incidence of CA-AKI was 9.9% versus 4.3% (p &lt; 0.001). The major determinants of CA-AKI in patients with CKD were the presence of diabetes and a reduced ejection fraction, as well as periprocedural blood loss, whereas a higher baseline hemoglobin and the use of the radial approach prevented CA-AKI.<br /><b>Conclusions</b><br />In patients with CKD CTO PCI could be performed successfully at a higher cost of CA-AKI.

MacCarthy P, Shah AM</i><br /><b>Background</b><br />We aimed to develop a machine learning algorithm to predict the presence of a culprit lesion in patients with out-of-hospital cardiac arrest (OHCA).<br /><b>Methods</b><br />We used the King\'s Out-of-Hospital Cardiac Arrest Registry, a retrospective cohort of 398 patients admitted to King\'s College Hospital between May 2012 and December 2017. The primary outcome was the presence of a culprit coronary artery lesion, for which a gradient boosting model was optimized to predict. The algorithm was then validated in two independent European cohorts comprising 568 patients.<br /><b>Results</b><br />A culprit lesion was observed in 209/309 (67.4%) patients receiving early coronary angiography in the development, and 199/293 (67.9%) in the Ljubljana and 102/132 (61.1%) in the Bristol validation cohorts, respectively. The algorithm, which is presented as a web application, incorporates nine variables including age, a localizing feature on electrocardiogram (ECG) (≥2 mm of ST change in contiguous leads), regional wall motion abnormality, history of vascular disease and initial shockable rhythm. This model had an area under the curve (AUC) of 0.89 in the development and 0.83/0.81 in the validation cohorts with good calibration and outperforms the current gold standard-ECG alone (AUC: 0.69/0.67/0/67).<br /><b>Conclusions</b><br />A novel simple machine learning-derived algorithm can be applied to patients with OHCA, to predict a culprit coronary artery disease lesion with high accuracy.<br /><br />© 2023 The Authors.

<div><h4>Prediction of new onset atrial fibrillation in patients with acute coronary syndrome undergoing percutaneous coronary intervention using the C2HEST and mC2HEST scores: A report from the multicenter REALE-ACS registry.</h4><i>Biccirè FG, Tanzilli G, Prati F, Sammartini E, ... Lip GYH, Pastori D</i><br /><b>Background</b><br />New onset atrial fibrillation (NOAF) is associated with worse clinical outcomes after acute coronary syndrome (ACS). Identification of ACS patients at risk of NOAF remains challenging. To test the value of the simple C<sub>2</sub>HEST score for predicting NOAF in patients with ACS.<br /><b>Methods</b><br />We studied patients from the prospective ongoing multicenter REALE-ACS registry of patients with ACS. NOAF was the primary endpoint of the study. The C<sub>2</sub>HEST score was calculated as coronary artery disease or chronic obstructive pulmonary disease (1 point each), hypertension (1 point), elderly (age ≥ 75 years, 2 points), systolic heart failure (2 points), thyroid disease (1 point). We also tested the mC<sub>2</sub>HEST score.<br /><b>Results</b><br />We enrolled 555 patients (mean age 65.6 ± 13.3 years; 22.9% women), of which 45 (8.1%) developed NOAF. Patients with NOAF were older (p &lt; 0.001) and had more prevalent hypertension (p = 0.012), chronic obstructive pulmonary disease (p &lt; 0.001) and hyperthyroidism (p = 0.018). Patients with NOAF were more frequently admitted with STEMI (p &lt; 0.001), cardiogenic shock (p = 0.008), Killip class ≥2 (p &lt; 0.001) and had higher mean GRACE score (p &lt; 0.001). Patients with NOAF had a higher C<sub>2</sub>HEST score compared with those without (4.2 ± 1.7 vs 3.0 ± 1.5, p &lt; 0.001). A C<sub>2</sub>HEST score &gt; 3 was associated with NOAF occurrence (odds ratio 4.33, 95% confidence interval 2.19-8.59, p &lt; 0.001). ROC curve analysis showed good accuracy of the C<sub>2</sub>HEST score (AUC 0.71, 95%CI 0.67-0.74) and mC<sub>2</sub>HEST score (AUC 0.69, 95%CI 065-0.73) in predicting NOAF.<br /><b>Conclusions</b><br />The simple C<sub>2</sub>HEST score may be a useful tool to identify patients at higher risk of developing NOAF after presentation with ACS.<br /><br />Copyright © 2023.

Abstract
<div><h4>Is spontaneous coronary artery dissection (SCAD) related to local anatomy and hemodynamics? An exploratory study.</h4><i>Candreva A, Rizzini ML, Schweiger V, Gallo D, ... Morbiducci U, Templin C</i><br /><b>Aims</b><br />Spontaneous coronary artery dissection (SCAD) is an increasingly diagnosed cause of myocardial infarction with unclear pathophysiology. The aim of the study was to test if vascular segments site of SCAD present distinctive local anatomy and hemodynamic profiles.<br /><b>Methods</b><br />Coronary arteries with spontaneously healed SCAD (confirmed by follow-up angiography) underwent three-dimensional reconstruction, morphometric analysis with definition of vessel local curvature and torsion, and computational fluid dynamics (CFD) simulations with derivation of time-averaged wall shear stress (TAWSS) and topological shear variation index (TSVI). The (reconstructed) healed proximal SCAD segment was visually inspected for co-localization with curvature, torsion, and CFD-derived quantities hot spots.<br /><b>Results</b><br />Thirteen vessels with healed SCAD underwent the morpho-functional analysis. Median time between baseline and follow-up coronary angiograms was 57 (interquartile range [IQR] 45-95) days. In seven cases (53.9%), SCAD was classified as type 2b and occurred in the left anterior descending artery or near a bifurcation. In all cases (100%), at least one hot spot co-localized within the healed proximal SCAD segment, in 9 cases (69.2%) ≥3 hot spots were identified. Healed SCAD in proximity of a coronary bifurcation presented lower TAWSS peak values (6.65 [IQR 6.20-13.2] vs. 3.81 [2.53-5.17] Pa, p = 0.008) and hosted less frequently TSVI hot spots (100% vs. 57.1%, p = 0.034).<br /><b>Conclusion</b><br />Vascular segments of healed SCAD were characterized by high curvature/torsion and WSS profiles reflecting increased local flow disturbances. Hence, a pathophysiological role of the interaction between vessel anatomy and shear forces in SCAD is hypothesized.<br /><br />Copyright © 2023 The Author. Published by Elsevier B.V.

<div><h4>Medium-Term Outcomes of the Different Antithrombotic Regimens After Transcatheter Aortic Valve Implantation.</h4><i>Naser JA, Kucuk HO, Gochanour BR, Scott CG, ... Nkomo VT, Pislaru SV</i><br /><AbstractText>Bioprosthetic valve thrombosis is associated with accelerated bioprosthesis degeneration and valve re-replacement. Whether 3-month warfarin use after transcatheter aortic valve implantation (TAVI) protects against such consequences is unknown. We aimed to investigate if 3-month warfarin treatment after TAVI is associated with better outcomes than dual antiplatelet therapy (DAPT) and single antiplatelet therapy (SAPT) at medium-term follow-up. Adults who underwent TAVI were identified retrospectively (n = 1,501) and classified into warfarin, DAPT, and SAPT groups based on antithrombotic regimen received. Patients with atrial fibrillation were excluded. Outcomes and valve hemodynamics were compared between the groups. Annualized change from baseline in mean gradients and effective orifice area at last follow-up echocardiography was calculated. Overall, 844 patients were included (mean age: 80 ± 9 years, 43% women; 633 receiving warfarin, 164 DAPT, and 47 SAPT). Median time to follow-up was 2.5 (interquartile range 1.2 to 3.9) years. There were no differences in the adjusted outcome end points of ischemic stroke, death, valve re-replacement/intervention, structural valve degeneration, or their composite end point at follow-up. Annualized change in aortic valve area was significantly higher in DAPT (-0.11 [0.19] cm<sup>2</sup>/year) than warfarin (-0.06 [0.25] cm<sup>2</sup>/y, p = 0.03), but annualized change in mean gradients was not different (p &gt;0.05). In conclusion, antithrombotic regimen, including warfarin, after TAVI was associated with marginally lower decrease in aortic valve area but no difference in medium-term clinical outcomes compared with DAPT and SAPT.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

Louvard Y, Stankovic G</i><br /><AbstractText>Provisional stenting has become the default technique for the treatment of most coronary bifurcation lesions. However, the side branch (SB) can become compromised after main vessel (MV) stenting and restoring SB patency can be difficult in challenging anatomies. Angiographic and intracoronary imaging criteria can predict the risk of side branch closure and may encourage use of side branch protection strategies. These protective approaches provide strategies to avoid SB closure or overcome compromise following MV stenting, minimising periprocedural injury. In this article, we analyse the strategies of SB preservation discussed and developed during the most recent European Bifurcation Club (EBC) meetings.</AbstractText><br /><br /><br /><br /><small>EuroIntervention: 15 May 2023; 19:26-36</small></div>

<div><h4>Impact of Gender, Race, and Insurance Status on Inhospital Management and Outcomes in Patients With COVID-19 and ST-Elevation Myocardial Infarction (a Nationwide Analysis).</h4><i>Patel KN, Majmundar M, Vasudeva R, Doshi R, ... Mehta H, Gupta K</i><br /><AbstractText>There is a paucity of data exploring the impact of gender, race, and insurance status on invasive management and inhospital mortality in patients with COVID-19 with ST-elevation myocardial infarction (STEMI) in the United States. The National Inpatient Sample database for the year 2020 was queried to identify all adult hospitalizations with STEMI and concurrent COVID-19. A total of 5,990 patients with COVID-19 with STEMI were identified. Women had 31% lower odds of invasive management and 32% lower odds of coronary revascularization than men. Black patients had lower odds of invasive management (odds ratio [OR] 0.61, 95% confidence interval [CI] 0.43 to 0.85, p = 0.004) than White patients. Black and Asian patients had lower odds of percutaneous coronary intervention (Black: OR 0.55, 95% CI 0.38 to 0.80, p = 0.002; Asian: OR 0.39, 95% CI 0.18 to 0.85, p = 0.018) than White patients. Uninsured patients had higher odds of getting percutaneous coronary intervention (OR 1.78, 95% CI 1.05 to 2.98, p = 0.031) and lower odds of inhospital mortality (OR 0.41, 95% CI 0.19 to 0.89, p = 0.023) than privately insured patients. Patients with out-of-hospital STEMI had 19 times higher odds of invasive management and 80% lower odds of inhospital mortality than inhospital STEMI. In conclusion, we note important gender and racial disparities in invasive management of patients with COVID-19 with STEMI. Surprisingly, uninsured patients had higher revascularization rates and lower mortality than privately insured patients.</AbstractText><br /><br />Copyright © 2023 The Author(s).

<div><h4>Ticagrelor as Compared to Clopidogrel Following Percutaneous Coronary Intervention for Acute Coronary Syndrome.</h4><i>Wiens EJ, Leon SJ, Whitlock R, Tangri N, Shah AH</i><br /><AbstractText>Dual antiplatelet therapy with acetylsalicylic acid and a P2Y12 inhibitor has become a mainstay of therapy after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). Although higher-potency P2Y12 inhibitors are preferred over clopidogrel in major society guidelines, recent evidence has questioned the extent of the benefit. It is important to evaluate the relative efficacy and safety of P2Y12 inhibitors in a real-world setting. This is a retrospective cohort study of all patients who underwent PCI for ACS in a Canadian province from January 1, 2015 to March 31, 2020. Baseline characteristics, including co-morbidities, medications, and bleeding risk, were obtained. Propensity matching was used to compare patients who received ticagrelor versus clopidogrel. The primary outcome was occurrence of major adverse cardiovascular events (MACEs) at 12 months, defined as death, nonfatal myocardial infarction, or unplanned revascularization. Secondary outcomes included all-cause mortality, major bleeding, stroke, and all-cause hospitalization. A total of 6,665 patients were included; 2,108 received clopidogrel and 4,214 received ticagrelor. Patients who received clopidogrel were older, had more co-morbidities, including cardiovascular risk factors, and had a higher bleeding risk. In 1.925 propensity score-matched pairs, ticagrelor was associated with a significantly lower risk of MACE (hazard ratio 0.79, 0.67 to 0.93, p &lt;0.01) and hospitalization (hazard ratio 0.85, 0.77 to 0.95, p &lt;0.01). No difference was observed in the risk of major bleeding. A statistically nonsignificant trend toward reduced risk of all-cause mortality was noted. In conclusion, in a real-world high-risk cohort, ticagrelor was associated with decreased risk of MACE and all-cause hospitalization compared with clopidogrel after PCI for ACS.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Contemporary Trends, Characteristics, and Outcomes of Transcatheter Aortic Valve Implantation Among Extreme Elderly Patients.</h4><i>Abdelmottaleb W, Maraey A, Ozbay M, Royfman R, ... Elzanaty A, Elgendy IY</i><br /><AbstractText>Transcatheter aortic valve implantation (TAVI) has been increasingly performed among extreme elderly patients with symptomatic severe aortic stenosis. We aimed to study the trends, characteristics, and outcomes of TAVI among extreme elderly. The National Readmission Database for the years 2016 to 2019 was queried for extreme elderly who underwent TAVI. Linear regression analysis was used to calculate the temporal trends in outcomes. A total of 23,507 TAVI extreme elderly admissions (50.3% women and 95.9% Medicare insurance) were included. The in-hospital mortality and all-cause 30-day readmissions were 2% and 15% and have been stable over years of analysis (p trend = 0.79 and 0.06, respectively). We evaluated complications, such as permanent pacemaker implantation (12%) and stroke (3.2%). Stroke rates did not decrease (3.4% vs 2.9% in 2016 and 2019 [p trend = 0.24]). The mean length of stay improved from 5.5 days in 2016 to 4.3 days in 2019 (p trend &lt;0.01). The rates of early discharge (day ≤3) has improved from 49% in 2016 to 69% in 2019 (p trend &lt;0.01). In conclusion, this nationwide contemporary observational analysis showed that TAVI was associated with low rates of complications in the extreme elderly.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Acute Intraoperative Bioprosthetic Valve Thrombosis Immediately After Protamine Administration.</h4><i>Teng P, Yuan S, Ni Y, Wu S</i><br /><AbstractText>Acute bioprosthetic valve thrombosis (BPVT) is considered a rare complication and has seldom been described. Moreover, acute intraoperative BPVT is exceedingly rare, and its management remains a major clinical challenge. Here, we report a case of acute intraoperative BPVT that occurred immediately after protamine administration. Major resolution of the thrombus and significant improvement of bioprosthetic function were observed after the resumption of cardiopulmonary bypass support for approximately 1 hour. Intraoperative transesophageal echocardiography is important for a prompt diagnosis. Our case describes the spontaneous resolution of BPVT after reheparinization, which might assist in the management of acute intraoperative BPVT.</AbstractText><br /><br />Copyright © 2023 The Author(s).

<div><h4>Changes in Computed-Tomography-Derived Segmental Left Ventricular Longitudinal Strain After Transcatheter Aortic Valve Implantation.</h4><i>Singh GK, Fortuni F, Kuneman JH, Vollema EM, ... Delgado V, Bax JJ</i><br /><AbstractText>Patients with severe aortic stenosis (AS) may show left ventricular (LV) apical longitudinal strain sparing. Transcatheter aortic valve implantation (TAVI) improves LV systolic function in patients with severe AS. However, the changes in regional longitudinal strain after TAVI have not been extensively evaluated. This study aimed to characterize the effect of the pressure overload relief after TAVI on LV apical longitudinal strain sparing. A total of 156 patients (mean age 80 ± 7 years, 53% men) with severe AS who underwent computed tomography before and within 1 year after TAVI (mean time to follow-up 50 ± 30 days) were included. LV global and segmental longitudinal strain were assessed using feature tracking computed tomography. LV apical longitudinal strain sparing was evaluated as the ratio between the apical and midbasal longitudinal strain and was defined as an LV apical to midbasal longitudinal strain ratio &gt;1. LV apical longitudinal strain remained stable after TAVI (from 19.5 ± 7.2% to 18.7 ± 7.7%, p = 0.20), whereas LV midbasal longitudinal strain showed a significant increase (from 12.9 ± 4.2% to 14.2 ± 4.0%, p ≤0.001). Before TAVI, 88% of the patients presented with LV apical strain ratio &gt;1% and 19% presented with an LV apical strain ratio &gt;2. After TAVI, these percentages significantly decreased to 77% and 5% (p = 0.009, p ≤0.001), respectively. In conclusion, LV apical sparing of strain is a relatively common finding in patients with severe AS who underwent TAVI and its prevalence decreases after the afterload relief after TAVI.</AbstractText><br /><br />Copyright © 2023 The Authors.

<div><h4>Coronary Volume to Left Ventricular Mass Ratio in Patients With Hypertension.</h4><i>van Rosendael SE, van Rosendael AR, Kuneman JH, Patel MR, ... Saraste A, Knuuti J</i><br /><AbstractText>The coronary vascular volume to left ventricular mass (V/M) ratio assessed by coronary computed tomography angiography (CCTA) is a promising new parameter to investigate the relation of coronary vasculature to the myocardium supplied. It is hypothesized that hypertension decreases the ratio between coronary volume and myocardial mass by way of myocardial hypertrophy, which could explain the detected abnormal myocardial perfusion reserve reported in patients with hypertension. Individuals enrolled in the multicenter ADVANCE (Assessing Diagnostic Value of Noninvasive FFRCT in Coronary Care) registry who underwent clinically indicated CCTA for analysis of suspected coronary artery disease with known hypertension status were included in current analysis. The V/M ratio was calculated from CCTA by segmenting the coronary artery luminal volume and left ventricular myocardial mass. In total, 2,378 subjects were included in this study, of whom 1,346 (56%) had hypertension. Left ventricular myocardial mass and coronary volume were higher in subjects with hypertension than normotensive patients (122.7 ± 32.8 g vs 120.0 ± 30.5 g, p = 0.039, and 3,105.0 ± 992.0 mm<sup>3</sup> vs 2,965.6 ± 943.7 mm<sup>3</sup>, p &lt;0.001, respectively). Subsequently, the V/M ratio was higher in patients with hypertension than those without (26.0 ± 7.6 mm<sup>3</sup>/g vs 25.3 ± 7.3 mm<sup>3</sup>/g, p = 0.024). After correcting for potential confounding factors, the coronary volume and ventricular mass remained higher in patients with hypertension (least square) mean difference estimate: 196.3 (95% confidence intervals [CI] 119.9 to 272.7) mm<sup>3</sup>, p &lt;0.001, and 5.60 (95% CI 3.42 to 7.78) g, p &lt;0.001, respectively), but the V/M ratio was not significantly different (least square mean difference estimate: 0.48 (95% CI -0.12 to 1.08) mm<sup>3</sup>/g, p = 0.116). In conclusion, our findings do not support the hypothesis that the abnormal perfusion reserve would be caused by reduced V/M ratio in patients with hypertension.</AbstractText><br /><br />Copyright © 2023 The Author(s).

We previously reported favorable 2-year outcomes for the PASCAL transcatheter valve repair system.<br /><b>Objectives</b><br />We report 3-year outcomes from the multinational, prospective, single-arm CLASP study with analysis by functional MR (FMR) and degenerative MR (DMR).<br /><b>Methods</b><br />Patients with core-lab determined MR ≥ 3+ were deemed candidates for M-TEER by the local heart team. Major adverse events were assessed by an independent clinical events committee to 1 year and by sites thereafter. Echocardiographic outcomes were evaluated by the core laboratory to 3 years.<br /><b>Results</b><br />The study enrolled 124 patients, 69% FMR; 31% DMR (60% NYHA class III-IVa, 100% MR ≥ 3+). The 3-year Kaplan-Meier estimate for survival was 75% (66% FMR; 92% DMR) and freedom from heart failure hospitalization (HFH) was 73% (64% FMR; 91% DMR), with 85% reduction in annualized HFH rate (81% FMR; 96% DMR) (p &lt; 0.001). MR ≤ 2+ was achieved and maintained in 93% of patients (93% FMR; 94% DMR) and MR ≤ 1+ in 70% of patients (71% FMR; 67% DMR) (p &lt; 0.001). The mean left ventricular end-diastolic volume (181 mL at baseline) decreased progressively by 28 mL [p &lt; 0.001].

<div><h4>A simply calculated nutritional index provides clinical implications in patients undergoing transcatheter aortic valve replacement.</h4><i>Sudo M, Shamekhi J, Aksoy A, Al-Kassou B, ... Nickenig G, Zimmer S</i><br /><b>Background</b><br />Malnutrition is associated with adverse outcomes in patients with aortic stenosis. The Triglycerides × Total Cholesterol × Body Weight Index (TCBI) is a simple scoring model to evaluate the status of nutrition. However, the prognostic relevance of this index in patients undergoing transcatheter aortic valve replacement (TAVR) is unknown. This study aimed to evaluate the association of the TCBI with clinical outcomes in patients undergoing TAVR.<br /><b>Methods</b><br />A total of 1377 patients undergoing TAVR were evaluated in this study. The TCBI was calculated by the formula; triglyceride (mg/dL) × total cholesterol (mg/dL) × body weight (kg)/1000. The primary outcome was all-cause mortality within 3 years.<br /><b>Results</b><br />Patients with a low TCBI, based on a cut-off value of 985.3, were more likely to have elevated right atrial pressure (p = 0.04), elevated right ventricular pressure (p &lt; 0.01), right ventricular systolic dysfunction (p &lt; 0.01), tricuspid regurgitation ≥ moderate (p &lt; 0.01). Patients with a low TCBI had a higher cumulative 3-year all-cause (42.3% vs. 31.6%, p &lt; 0.01; adjusted HR 1.36, 95% CI 1.05-1.77, p = 0.02) and non-cardiovascular mortality (15.5% vs. 9.1%, p &lt; 0.01; adjusted HR 1.95, 95% CI 1.22-3.13, p &lt; 0.01) compared to those with a high TCBI. Adding a low TCBI to EuroSCORE II improved the predictive value for 3-year all-cause mortality (net reclassification improvement, 0.179, p &lt; 0.01; integrated discrimination improvement, 0.005, p = 0.01).<br /><b>Conclusion</b><br />Patients with a low TCBI were more likely to have right-sided heart overload and exhibited an increased risk of 3-year mortality.

However, initial trials demonstrated worse early outcomes with BVS, in part due to suboptimal technique. In the large-scale, blinded ABSORB IV trial, polymeric everolimus-eluting BVS implanted with improved technique demonstrated non-inferior 1-year outcomes compared with cobalt chromium everolimus-eluting stents (CoCr-EES).<br /><b>Objectives</b><br />To evaluate the long-term outcomes from the ABSORB IV trial.<br /><b>Methods</b><br />We randomized 2,604 patients at 147 sites with stable or acute coronary syndromes to BVS with improved technique vs. CoCr-EES. Patients, clinical assessors and event adjudicators were blinded to randomization. Five-year follow-up was completed.<br /><b>Results</b><br />Target lesion failure (TLF) at 5 years occurred in 216 patients (17.5%) assigned to BVS and 180 patients (14.5%) assigned to CoCr-EES (P=0.03). Device thrombosis within 5 years occurred in 21 (1.7%) BVS and 13 (1.1%) CoCr-EES patients (P=0.15). Event rates were slightly greater with BVS than CoCr-EES through 3-year follow-up and similar between 3-5 years. Angina, also centrally adjudicated, recurred within 5 years in 659 patients (cumulative rate 53.0%) assigned to BVS and 674 patients (53.3%) assigned to CoCr-EES (P=0.63).<br /><b>Conclusions</b><br />In this large-scale, blinded randomized trial, despite improved implantation technique the absolute 5-year rate of TLF was 3% greater after BVS compared with CoCr-EES. The risk period for increased events was restricted to 3 years, the time point of complete scaffold bioresorption; event rates were similar thereafter. Angina recurrence after intervention was frequent during 5-year follow-up but was comparable with both devices.<br /><br />Copyright © 2023.

<div><h4>The prognostic value of ORBIT risk score in predicting major bleeding in patients with acute coronary syndrome.</h4><i>Günlü S, Arpa A, Kayan F, Güzel T, ... Altintaş B, Karahan MZ</i><br /><b>Background</b><br />The most significant adverse effect of antithrombotic medication in acute coronary syndrome (ACS) is major bleeding, which is related to increased mortality. Studies on ORBIT risk score in predicting major bleeding in ACS patients are limited.<br /><b>Objective</b><br />This research aimed to examine whether the ORBIT score calculated at the bedside can identify major bleeding risk in patients with ACS.<br /><b>Methods</b><br />This research was retrospective, observational, and conducted at a single center. Analyses of receiver operating characteristics (ROC) were utilized to define the diagnostic value of CRUSADE and ORBIT scores. The predictive performances of the two scores were compared using DeLong\'s method. Discrimination and reclassification performances were evaluated by the integrated discrimination improvement (IDI), and net reclassification improvement (NRI).<br /><b>Results</b><br />The study included 771 patients with ACS. The mean age was 68.7 ± 8.6 years, with 35.3 % females. 31 patients had major bleeding. Twenty-three of these patients were BARC 3 A, five were BARC 3 B, and three were BARC 3 C. Bleeding history [OR (95 % CI), 2.46 (1.02-5.94), p = 0.021], hemoglobin levels [OR (95 % CI), 0.54 (0.45-0.63), p &lt; 0.001], and age &gt; 74 years [OR (95 % CI), 1.03 (1.01-1.06), p = 0.039] were independent predictors of major bleeding. The ORBIT score was an independent predictor of major bleeding in the multivariate analysis: continuous variables [OR (95 % CI), 2.53 (2.61-3.95), p &lt; 0.001] and risk categories [OR (95 % CI), 3.06 (1.69-5.52), p &lt; 0.001]. Comparison of c-indexes for major bleeding events revealed a non-significant difference for the discriminative ability of the two tested scores (p = 0.07) with a continuous NRI of 6.6 % (p = 0.026) and an IDI of 4.2 % (p &lt; 0.001).<br /><b>Conclusion</b><br />In ACS patients, the ORBIT score independently predicted major bleeding.<br /><br />Copyright © 2023 Elsevier Ltd.

<div><h4>Applied coronary physiology for planning and guidance of percutaneous coronary interventions. A clinical consensus statement from the European Association of Percutaneous Cardiovascular Interventions (EAPCI) of the European Society of Cardiology.</h4><i>Escaned J, Berry C, De Bruyne B, Shabbir A, ... Stefanini G, Tarantini G</i><br /><AbstractText>The clinical value of fractional flow reserve and non-hyperaemic pressure ratios are well established in determining an indication for percutaneous coronary intervention (PCI) in patients with coronary artery disease (CAD). In addition, over the last 5 years we have witnessed a shift towards the use of physiology to enhance procedural planning, assess post-PCI functional results, and guide PCI optimisation. In this regard, clinical studies have reported compelling data supporting the use of longitudinal vessel analysis, obtained with pressure guidewire pullbacks, to better understand how obstructive CAD contributes to myocardial ischaemia, to establish the likelihood of functionally successful PCI, to identify the presence and location of residual flow-limiting stenoses and to predict long-term outcomes. The introduction of new functional coronary angiography tools, which merge angiographic information with fluid dynamic equations to deliver information equivalent to intracoronary pressure measurements, are now available and potentially also applicable to these endeavours. Furthermore, the ability of longitudinal vessel analysis to predict the functional results of stenting has played an integral role in the evolving field of simulated PCI. Nevertheless, it is important to have an awareness of the value and challenges of physiology-guided PCI in specific clinical and anatomical contexts. The main aim of this European Association of Percutaneous Cardiovascular Interventions clinical consensus statement is to offer up-to-date evidence and expert opinion on the use of applied coronary physiology for procedural PCI planning, disease pattern recognition and post-PCI optimisation.</AbstractText><br /><br /><br /><br /><small>EuroIntervention: 12 May 2023; epub ahead of print</small></div>

<div><h4>Configuration of two-stent coronary bifurcation techniques in explanted beating hearts: the MOBBEM study.</h4><i>Cangemi S, Burzotta F, Bianchini F, DeVos A, ... Stankovic G, Iaizzo PA</i><br /><b>Background</b><br />In patients with complex coronary bifurcation lesions undergoing percutaneous coronary intervention (PCI), various 2-stent techniques might be utilised. The Visible Heart Laboratories (VHL) offer an experimental environment where PCI results can be assessed by multimodality imaging.<br /><b>Aims</b><br />We aimed to assess the post-PCI stent configuration achieved by 2-stent techniques in the VHL and to evaluate the procedural factors associated with suboptimal results.<br /><b>Methods</b><br />Bifurcation PCI with 2-stent techniques, performed by expert operators in the VHL on explanted beating swine hearts, was studied. The adopted bifurcation PCI strategy and the specific procedural steps applied in each procedure were classified according to Main, Across, Distal, Side (MADS)-2 and to their adherence to the European Bifurcation Club (EBC) recommendations. Microcomputed tomography (micro-CT) was used to assess the post-PCI stent configuration. The primary endpoint was \"suboptimal stent implantation\", defined as a composite of stent underexpansion (&lt;90%), side branch ostial area stenosis &gt;50% and the gap between stents.<br /><b>Results</b><br />A total of 82 PCI with bifurcation stenting were assessed, comprised of 29 crush, 25 culotte, 28 T/T and small protrusion (TAP) techniques. Suboptimal stent implantation was observed in as many as 53.7% of the cases, regardless of baseline anatomy or the stenting strategy. However, less frequent use of the proximal optimisation technique (POT; p=0.015) and kissing balloon inflations (KBI; p=0.027) and no adherence to EBC recommendations (p=0.004, p multivariate=0.006) were significantly associated with the primary endpoint.<br /><b>Conclusions</b><br />Commonly practised bifurcation 2-stent techniques may result in imperfect stent configurations. More frequent use of POT/KBI and adherence to expert recommendations might reduce the occurrence of post-PCI suboptimal stent configurations.<br /><br /><br /><br /><small>EuroIntervention: 12 May 2023; epub ahead of print</small></div>

<div><h4>Mild aortic insufficiency following transcatheter aortic valve replacement: A systematic review and meta-analysis.</h4><i>Hameed I, Ahmed A, Kumar A, Li E, ... Geirsson A, Williams ML</i><br /><b>Background</b><br />Post-procedural aortic insufficiency (AI) continues to be prevalent following transcatheter aortic valve replacement (TAVR). While several studies have assessed the outcomes of moderate-severe AI following TAVR, the incidence, predictors, and outcomes of mild AI remain unclear.<br /><b>Methods</b><br />A systematic literature review was performed to identify studies reporting on mild AI following TAVR. The primary outcome was pooled incidence of post-TAVR mild AI. Secondary outcomes included pooled incidence of mild AI at 30 days and long term. The pooled incidence of midterm mortality in patients with post-TAVR mild AI was also evaluated. The random effect generalized linear mixed-effects model with logit-transformed proportions and Hartung-Knapp adjustment was used to calculate pooled incidence rates. Meta-regression was performed to identify predictors of mild AI.<br /><b>Results</b><br />The pooled analysis included 19,241 patients undergoing TAVR across 50 studies. The mean age of patients ranged from 73 to 85 years, and female patients ranged from 20.0% to 83.3%. The overall pooled incidence of post-TAVR mild AI was 56.1% (95% confidence interval [CI] 0.31-0.64). The pooled incidence of mild AI at 30 days was 33.7% (95% CI 0.12-0.37). At mean follow-up of 1.15 years, the pooled incidence of mild AI was 37.0% (95% CI 0.16-0.45). The overall pooled incidence of Midterm mortality (mean follow-up 1.22 years) in patients with mild AI was 14.8% (95% CI 0.10-0.25). At meta-regression, none of the explored variables correlated with a difference in mild AI incidence.<br /><b>Conclusions</b><br />In published studies to date, 50% of patients undergoing TAVR develop mild AI postoperatively. In 37% of patients, this persists in long term. Though the incidence of AI is likely improving with newer generation TAVR valves, the prevalence and outcomes of mild AI should be closely monitored as TAVR volume and indications expand to younger patients with long life expectancy. The long-term outcomes of mild AI remain unclear. Further dedicated studies on post-TAVR mild AI are needed.<br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 12 May 2023; epub ahead of print</small></div>

<div><h4>Aortocoronary dissection during percutaneous coronary interventions for chronic total occlusion: Insights from the PROGRESS-CTO registry.</h4><i>Kostantinis S, Rempakos A, Simsek B, Karacsonyi J, ... Burke MN, Brilakis ES</i><br /><b>Background</b><br />Aortocoronary dissection is a potentially serious complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI).<br /><b>Methods</b><br />We examined the incidence, mechanisms, treatment, and outcomes of aortocoronary dissection among 12,117 CTO PCIs performed between 2012 and 2022 in a large multicenter CTO PCI registry.<br /><b>Results</b><br />The incidence of aortocoronary dissection was 0.2% (n = 27). Most aortocoronary dissections occurred in the right coronary artery (96.3%, n = 26). The baseline clinical characteristics of patients with and without aortocoronary dissection were similar, except for dyslipidemia, which was less common in patients with aortocoronary dissection (70.4% vs. 86.0%; p = 0.019). The retrograde approach was used more commonly among cases complicated by aortocoronary dissection (59.3% vs. 31.0%; p = 0.002). Technical (74.1% vs. 86.6%; p = 0.049) and procedural (70.4% vs. 85.2%; p = 0.031) success rates were lower among aortocoronary dissection cases, with a similar incidence of in-hospital major adverse cardiovascular events (3.7% vs. 2.0%; p = 0.541). Of the 27 patients with aortocoronary dissection, 19 (70.4%) were treated with ostial stenting and 8 (29.6%) were treated conservatively without subsequent adverse clinical outcomes. No patients required emergency surgery. Follow-up was available for 22 patients (81.5%): during a mean follow up of 767 (±562) days, the incidence of in-stent restenosis was 11.1% (n = 3).<br /><b>Conclusions</b><br />Aortocoronary dissection occurred in 0.2% of CTO PCIs performed by experienced operators, was associated with lower technical and procedural success, and was treated most commonly with ostial stenting.

Galié N, Taglieri N</i><br /><b>Background</b><br />Drug-coated balloons (DCBs) have shown comparable results with drug-eluting stents in small vessel disease (SVD) percutaneous coronary intervention (PCI) in terms of target vessel revascularization and a reduced incidence of myocardial infarction. However, the relatively high rate of bail-out stenting (BOS) still represents a major drawback of DCB PCI.<br /><b>Aims</b><br />The aim of the study was to investigate the clinical, anatomic, and procedural features predictive of BOS after DCB PCI in SVD.<br /><b>Methods</b><br />We included all consecutive patients undergoing PCI at our institution between January 2020 and May 2022 who were treated with DCB PCI of a de novo lesion in a coronary vessel with a reference vessel diameter (RVD) between 2.0 and 2.5 mm. Angiographic success was defined as a residual stenosis &lt;30% without flow-limiting dissection. Patients who did not meet these criteria underwent BOS.<br /><b>Results</b><br />A total of 168 consecutive patients and 216 coronary stenoses were included. The rate of bail-out stent was 13.9%. On multivariate analysis, DCB/RVD ratio (odds ratio [OR]: 4.39, 95% confidence interval [CI]: 1.71-11.29, p &lt; 0.01), vessel tortuosity (OR: 7.00, 95% CI: 1.66-29.62, p &lt; 0.01), distal vessel disease (OR: 5.66, 95% CI: 2.02-15.83, p &lt; 0.01), and high complexity (Grade C of ACC/AHA classification) coronary stenoses (OR: 6.31, 95% CI: 1.53-26.04, p = 0.01) were independent predictors of BOS.<br /><b>Conclusions</b><br />BOS is not an infrequent occurrence in DCB PCI of small vessels and is correlated with vessel tortuosity, distal diffuse vessel disease, higher lesion complexity, and balloon diameter oversizing.<br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 12 May 2023; epub ahead of print</small></div>

Important sources of bleeding include the arterial access site and coronary artery perforation. Prompt and effective management of hemorrhagic complications is an essential interventional skill. Protamine sulfate is well-known as a heparin reversal agent. Despite this, there is heterogeneity in the use of protamine during interventional procedures. While protamine is generally well-tolerated, it is associated with a risk of hypersensitivity reaction, including anaphylaxis, among others.

Based on angiography and OCT before PCI, simulated residual OCT-μQFR was computed by assuming full stent expansion to the intended-to-treat segment. Plaque composition was automatically characterized using a validated artificial intelligence algorithm. Actual post-PCI OCT-μQFR pullback was computed based on coregistration of angiography and OCT acquired immediately after PCI. Suboptimal functional stenting result was defined as OCT-μQFR ≤ 0.90.<br /><b>Results</b><br />Paired simulated residual OCT-μQFR and actual post-PCI OCT-μQFR were obtained in 76 vessels from 74 patients. Simulated residual OCT-μQFR showed good correlation (r = 0.80, p &lt; 0.001), agreement (mean difference = -0.02 ± 0.02, p &lt; 0.001), and diagnostic concordance (79%, 95% confidence interval: 70%-88%) with actual post-PCI OCT-μQFR. Actual post-PCI in-stent OCT-μQFR had a median value of 0.02 and was associated with left anterior descending artery lesion location (β = 0.38, p &lt; 0.001), higher baseline total plaque burden (β = 0.25, p = 0.031), and fibrous plaque volume (β = 0.24, p = 0.026).<br /><b>Conclusions</b><br />This study based on patients enrolled in a prospective OCT-guidance PCI trial shows that simulated residual OCT-μQFR had good correlation, agreement, and diagnostic concordance with actual post-PCI OCT-μQFR.

Kovarnik T, Belohlavek J</i><br /><b>Background</b><br />Refractory out-of-hospital cardiac arrest (r-OHCA) in patients with pulmonary embolism (PE) is associated with poor outcomes. The role of extracorporeal cardiopulmonary resuscitation (ECPR) in this patient group is uncertain. This study aims to analyze clinical course, outcomes, and the effect of an invasive procedure, including ECPR, in a randomized population.<br /><b>Methods</b><br />A post-hoc analysis of a randomized controlled trial (Prague OHCA study) was conducted to evaluate the effect of ECPR vs. a standard approach in r-OHCA. A subgroup of patients with PE-related r-OHCA was identified, and procedural and outcome characteristics, including favorable neurological survival, organ donation, and complications, were compared to patients without PE.<br /><b>Results</b><br />PE was identified as a cause of r-OHCA in 24 of 256 (9.4%) enrolled patients. Patients with PE were more likely to be women (12/24 [50%] vs. 32/232 [13.8%]; p &lt; 0.001) and presented more frequently with an initial non-shockable rhythm (23/24 [95.8%] vs. 77/232 [33.2%]; p &lt; 0.001), as well as more severe acidosis at admission (median pH [interquartile range]; 6.83 [6.75-6.88] vs. 6.98 [6.82-7.14]; p &lt; 0.001). Their favorable 180 - days neurological survival was significantly lower (2/24 [8.3%] vs. 66/232 [28.4%]; P = 0.049), but the proportion of accepted organ donors was higher (16.7 vs. 4.7%, p = 0.04).<br /><b>Conclusion</b><br />r-OHCA due to PE has a different presentation and inferior outcomes compared to other causes but may represent an important source of organ donations.

<div><h4>Sodium-Glucose Cotransporter 2 Inhibitor Use in Early-Phase Acute Coronary Syndrome with Severe Heart Failure.</h4><i>Kanaoka K, Iwanaga Y, Nakai M, Nishioka Y, ... Saito Y, Imamura T</i><br /><b>Aims</b><br />Sodium-glucose cotransporter 2 inhibitor (SGLT2i) improves clinical outcomes in patients with heart failure (HF), but has limited evidence of SGLT2i use on early-phase acute coronary syndrome (ACS). We determined association of early SGLT2i use compared with either non-SGLT2i or dipeptidyl peptidase 4 inhibitor (DPP4i) in hospitalized patients with ACS.<br /><b>Methods and results</b><br />This retrospective cohort study that used the Japanese nationwide administrative claims database included patients hospitalized with ACS aged ≥ 20 years between April 2014 and March 2021. The primary outcome was a composite of all-cause mortality or HF/ACS rehospitalization. Using 1:1 propensity score matching, the association with outcomes of the early SGLT2i use (≤14 days after admission) compared with non-SGLT2i or DPP4i was determined according to the HF treatment. Among 388 185 patients included, 115 612 and 272 573 with and without severe HF, respectively. Compared to non-SGLT2i users, the SGLT2i users had a lower hazard ratio (HR) with the primary outcome (HR: 0.83, 95% confidence interval [CI]: 0.76-0.91, p &lt; 0.001) in the severe HF group; however, there was no significant difference in the non-severe HF group (HR: 0.92, 95% CI: 0.82-1.03, p = 0.16). SGLT2i use showed a lower risk of the outcome in patients with severe HF and diabetes compared with DPP4i (HR: 0.83, 95% CI: 0.69-1.00, p = 0.049).<br /><b>Conclusion</b><br />SGLT2i use in patients with early-phase ACS showed a lower risk of primary outcome in patients with severe HF but the effect was not apparent in patients without severe HF.<br /><br />© The Author(s) 2023.

<div><h4>Coronary Lithotripsy as Elective or Bail-Out Strategy After Rotational Atherectomy in the Rota-Shock Registry.</h4><i>Sardella G, Stefanini G, Leone PP, Boccuzzi G, ... Tomai F, Mancone M</i><br /><AbstractText>Debulking lesions with severe coronary artery calcification (CAC) is highly recommended to obtain good procedural and long-term success. Utilization and performance of coronary intravascular lithotripsy (IVL) after rotational atherectomy (RA) has not been thoroughly studied. This study aimed to evaluate the efficacy and safety of IVL with the Shockwave Coronary Rx Lithotripsy System in lesions with severe CAC as elective or bail-out strategy after RA. This observational, prospective, single-arm, multicenter, international, open-label Rota-Shock registry included patients with symptomatic coronary artery disease and lesions with severe CAC treated by percutaneous coronary intervention, including lesion preparation with RA and IVL, at 23 high-volume centers. Primary efficacy end point was procedural success, defined as final diameter stenosis &lt;30% by quantitative coronary angiography. Primary safety end point was freedom from serious angiographic complications, which included &gt;National Heart, Lung and Blood Institute type B dissection, perforation, abrupt closure, slow or no flow, final thrombolysis in myocardial infarction flow &lt;3, and acute thrombosis. A total of 160 patients were enrolled between June 2020 and June 2022. The primary efficacy end point was observed in 155 patients (96.9%). The primary safety end point occurred in 145 cases (90.6%). Dissections &gt;National Heart, Lung and Blood Institute type B occurred in 3 patients (1.9%), whereas slow or no flow occurred in 8 (5.0%), final thrombolysis in myocardial infarction flow &lt;3 in 3 (1.9%), and perforation in 4 patients (2.5%). Free from inhospital major adverse cardiac and cerebrovascular events, including cardiac death, target vessel myocardial infarction, target lesion revascularization, cerebrovascular accident, definite/probable stent thrombosis, and major bleeding, occurred in 158 patients (98.7%). In conclusion, IVL after RA in lesions with severe CAC was effective and safe, with a very low incidence of complications as either elective or bail-out strategy.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Transcatheter Aortic Valve Implantation in Cardiac Amyloidosis and Aortic Stenosis.</h4><i>Riley JM, Junarta J, Ullah W, Siddiqui MU, ... Rajapreyar IN, Brailovsky Y</i><br /><AbstractText>Aortic stenosis (AS) and cardiac amyloidosis (CA) occur concomitantly in a significant number of patients and portend a higher risk of all-cause mortality. Previous studies have investigated outcomes in patients with concomitant CA/AS who underwent transcatheter aortic valve implantation (TAVI) versus medical therapy alone, but no evidence-based consensus regarding the ideal management of these patients has been established. Medline, Scopus, and Cochrane Central Register of Controlled Trials were systematically searched to identify relevant studies. Methodologic bias was assessed using the modified Newcastle-Ottawa scale for observational studies. A total of 4 observational studies comprising 83 patients were included. Of these, 45 patients (54%) underwent TAVI, whereas 38 (46%) were managed conservatively. Of the 3 studies that included baseline characteristics by treatment group, 30% were women. The risk of all-cause mortality was found to be significantly lower in patients who underwent TAVI than those treated with conservative medical therapy alone (odds ratio 0.24, 95% confidence interval 0.08 to 0.73). In conclusion, this meta-analysis suggests a lower risk of all-cause mortality in patients with CA with AS who underwent TAVI than those managed with medical therapy alone.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

<div><h4>Transcatheter Treatment of Native Aortic Valve Regurgitation: The North American Experience with a Novel Device.</h4><i>Garcia S, Ye J, Webb J, Reardon M, ... Jollis JG, Kereiakes DJ</i><br /><b>Background</b><br />Transcatheter treatment of native aortic valve regurgitation (AR) has been limited by anatomic factors. No transcatheter device has received U.S. regulatory approval for the treatment of AR.<br /><b>Objectives</b><br />To describe the compassionate use experience in North America with a dedicated transcatheter device (J-Valve, J.C. Medical, Burlingame, CA).<br /><b>Methods</b><br />Multicenter, observational registry of compassionate use cases of J-Valve for the treatment of patients with severe symptomatic aortic regurgitation and elevated surgical risk in North America. The J-Valve consists of a self-expanding nitinol frame, bovine pericardial leaflets, and a valve locating feature. The available size matrix (5 sizes) can treat a wide range of anatomies (minimum/maximal annular perimeters 57-109 mm).<br /><b>Results</b><br />A total of 27 patients (median age 81 [72-85], 81% high surgical risk, 96% NYHA FC III-IV) with native valve AR were treated with J-Valve during the study period (2018-2022). Procedural success (J-Valve delivered to the intended location without need for surgical conversion or a second THV) was 81% (22 out 27 cases) in the overall experience and 100% in the last 15 cases. Two cases required conversion to surgery in the early experience leading to changes in valve design. At 30-days, there were 1 death, 1 stroke, 3 new pacemakers (13%), and 88% of patients were NYHA FC I-II. No patient had residual AR ≥ moderate at 30-days.<br /><b>Conclusion</b><br />J-Valve appears to provide a safe and effective alternative to surgery in patients with pure aortic regurgitation and elevated/prohibitive surgical risk.<br /><br />Copyright © 2023.

<div><h4>Sex and age-specific interactions of coronary atherosclerotic plaque onset and prognosis from coronary computed tomography.</h4><i>van Rosendael SE, Bax AM, Lin FY, Achenbach S, ... Shaw LJ, van Rosendael AR</i><br /><b>Aims</b><br />The totality of atherosclerotic plaque derived from coronary computed tomography angiography (CCTA) emerges as a comprehensive measure to assess the intensity of medical treatment that patients need. This study examines the differences in age onset and prognostic significance of atherosclerotic plaque burden between sexes.<br /><b>Methods and results</b><br />From a large multi-center CCTA registry the Leiden CCTA score was calculated in 24 950 individuals. A total of 11 678 women (58.5 ± 12.4 years) and 13 272 men (55.6 ± 12.5 years) were followed for 3.7 years for major adverse cardiovascular events (MACE) (death or myocardial infarction). The age where the median risk score was above zero was 12 years higher in women vs. men (64-68 years vs. 52-56 years, respectively, P &lt; 0.001). The Leiden CCTA risk score was independently associated with MACE: score 6-20: HR 2.29 (1.69-3.10); score &gt; 20: HR 6.71 (4.36-10.32) in women, and score 6-20: HR 1.64 (1.29-2.08); score &gt; 20: HR 2.38 (1.73-3.29) in men. The risk was significantly higher for women within the highest score group (adjusted P-interaction = 0.003). In pre-menopausal women, the risk score was equally predictive and comparable with men. In post-menopausal women, the prognostic value was higher for women [score 6-20: HR 2.21 (1.57-3.11); score &gt; 20: HR 6.11 (3.84-9.70) in women; score 6-20: HR 1.57 (1.19-2.09); score &gt; 20: HR 2.25 (1.58-3.22) in men], with a significant interaction for the highest risk group (adjusted P-interaction = 0.004).<br /><b>Conclusion</b><br />Women developed coronary atherosclerosis approximately 12 years later than men. Post-menopausal women within the highest atherosclerotic burden group were at significantly higher risk for MACE than their male counterparts, which may have implications for the medical treatment intensity.<br /><br />© The Author(s) 2023.

<div><h4>Thromboembolic risk scores in patients with non-obstructive coronary architecture with and without coronary slow flow: A case-control study.</h4><i>Genç Ö, Yildirim A, Alici G, Harbalioğlu H, ... Şeker T, Güler A</i><br /><b>Aim</b><br />Coronary slow flow phenomenon (CSFP) detected on coronary angiography (CA) has been related to poor prognosis. We sought to examine the relationship between thromboembolic risk scores, routinely used in cardiology practice, and CSFP.<br /><b>Methods</b><br />This single-center, retrospective, case-control study comprised 505 individuals suffering from angina and had verified ischemia between January 2021 and January 2022. Demographic and laboratory parameters were obtained from the hospital database. The following risk scores were calculated; CHA<sub>2</sub>DS<sub>2</sub>-VASc, M-CHA<sub>2</sub>DS<sub>2</sub>-VASc, CHA<sub>2</sub>DS<sub>2</sub>-VASc-HS, R<sub>2</sub>-CHA<sub>2</sub>DS<sub>2</sub>-VASc, M-R<sub>2</sub>-CHA<sub>2</sub>DS<sub>2</sub>-VASc, ATRIA, M-ATRIA, M-ATRIA-HSV. The overall population was divided into two groups; coronary slow flow and coronary normal flow. Multivariable logistic regression was performed to compare risk scores between patients with and without CSFP. Pairwise comparisons were then undertaken to test performance in determining CSFP.<br /><b>Results</b><br />The mean age was 51.7 ± 10.7 years, of whom 63.2% were male. CSFP was detected in 222 patients. Those with CSFP had higher rates of male gender, diabetes, smoking, hyperlipidemia, and vascular disease. All scores were higher in CSFP patients. Multivariable logistic regression analysis found that CHA<sub>2</sub>DS<sub>2</sub>-VASc-HS score was the most powerful determinant of CSFP among all risk schemes (for each one-point increase in score OR = 1.90, p &lt; 0.001; for score of 2-3 OR = 5.20, p &lt; 0.001; for score of &gt;4 OR = 13.89, p &lt; 0.001). Also, the CHA<sub>2</sub>DS<sub>2</sub>-VASc-HS score provided the best discriminative performance, with a cut-off value of ≥2 in identifying CSFP (AUC = 0.759, p &lt; 0.001).<br /><b>Conclusion</b><br />We showed that thromboembolic risk scores may be associated with CSFP in patients with non-obstructive coronary architecture who underwent CA. The CHA<sub>2</sub>DS<sub>2</sub>-VASc-HS score had the best discriminative ability.<br /><br />Copyright © 2023.

Abstract
<div><h4>EXpansion of stents after intravascular lithoTripsy versus conventional predilatation in CALCified coronary arteries.</h4><i>Oomens T, Vos NS, van der Schaaf RJ, Amoroso G, ... Slagboom T, Vink MA</i><br /><b>Background</b><br />Coronary artery calcification is a strong predictor for procedural failure and is independently associated with adverse events after percutaneous coronary intervention (PCI). An important contributor to the impaired outcome is the inability to achieve optimal results due to stent underexpansion or stent deformation/fracture. Intravascular lithotripsy (IVL) has emerged as an alternative technique to change the integrity of calcified plaques.<br /><b>Aims</b><br />Our aim was to investigate if pre-treatment with IVL in severely calcified lesions increases stent expansion, assessed by optical coherence tomography (OCT), when compared to predilatation with conventional and/or specialty balloon strategy.<br /><b>Methods</b><br />EXIT-CALC was a prospective, single-centre, randomised controlled study. Patients with an indication for PCI and severe calcification of the target lesion were allocated to predilatation with conventional angioplasty balloons or pre-treatment with IVL, followed by drug-eluting stenting and mandatory postdilatation. Primary endpoint was stent expansion assessed by OCT. Secondary endpoints were the occurrence of peri-procedural events and major adverse cardiac events (MACE) in hospital and during follow-up.<br /><b>Results</b><br />A total of 40 patients were included. The minimal stent expansion in the IVL-group (n = 19) was 83.9 ± 10.3% and 82.2 ± 11.5% in the conventional group (n = 21) (p = 0.630). Minimal stent area was 6.6 ± 1.5 mm<sup>2</sup> and 6.2 ± 1.8 mm<sup>2</sup>, respectively (p = 0.406). No peri-procedural, in-hospital and 30-day follow-up MACE were reported.<br /><b>Conclusions</b><br />In severely calcified coronary lesions we found no significant difference in stent expansion measured by OCT when comparing IVL, as plaque modification, with conventional and/or specialty angioplasty balloons.<br /><br />Copyright © 2023.

<div><h4>Association between trajectories in cardiac damage and clinical outcomes after transcatheter aortic valve replacement.</h4><i>Zhou Y, Lin X, Zhu Q, Li H, ... Liu X, Wang J</i><br /><b>Background</b><br />There is little evidence of evolution in cardiac damage after transcatheter aortic valve replacement (TAVR) in aortic stenosis (AS) patients. Less is known about the prognostic value and potential utility of different cardiac damage trajectories following TAVR.<br /><b>Objectives</b><br />This study aims to investigate the cardiac damage trajectories following TAVR and explore their association with subsequent clinical outcomes.<br /><b>Methods</b><br />AS patients undergoing TAVR were enrolled and classified into five cardiac damage stages (0-4) based on the echocardiographic staging classification retrospectively. They were further grouped into early stage (stage 0-2) and advanced stage (stage 3-4). The cardiac damage trajectories in TAVR recipients were evaluated according to their trend between baseline and 30 days after TAVR.<br /><b>Results</b><br />A total of 644 TAVR recipients were enrolled, with four distinct trajectories identified. Compared to patients with early-early trajectory, patients with early-advanced trajectory were at 30-fold risk of all-cause death (HR 30.99, 95% CI 13.80-69.56; p &lt; 0.001). In multivariable analyses, early-advanced trajectory was associated with higher 2-year all-cause death (HR 24.08, 95% CI 9.07-63.90; p &lt; 0.001), cardiac death (HR 19.34, 95% CI 3.06-122.34; p &lt; 0.05), and cardiac rehospitalization (HR 4.19, 95% CI 1.49-11.76; p &lt; 0.05) after TAVR.<br /><b>Conclusions</b><br />This investigation provided insight into four cardiac damage trajectories in TAVR recipients and confirmed the prognostic value of distinct trajectories.

Køber L, Fosbøl EL</i><br /><b>Background</b><br />Valve-in-valve-transcatheter aortic valve implantation (TAVI) is a feasible and increasingly used treatment option for failed surgical aortic prosthesis, but data from clinical practice are limited.<br /><b>Objectives</b><br />We aimed to examine patient characteristics and outcomes of patients undergoing TAVI in a surgical valve (valve-in-valve TAVI) compared with patients undergoing TAVI in a native valve.<br /><b>Methods</b><br />Using nationwide registries, we identified all Danish citizens, who underwent TAVI from January 1, 2008, to December 31, 2020.<br /><b>Results</b><br />A total of 6070 patients undergoing TAVI were identified; 247 (4%) patients had a history of SAVR (The valve-in-valve cohort). The median age of the study population was 81 (25<sup>th</sup>-75<sup>th</sup> percentile 77-85) and 55% were men. Patients with valve-in-valve-TAVI were younger but had a greater burden of cardiovascular comorbidities compared with patients with native-valve-TAVI. Within 30 days post-procedure, 11 (0.2%) and 748 (13.8%) patients who underwent valve-in-valve-TAVI and native-valve-TAVI, respectively, had a pacemaker implantation. The cumulative 30-day risk of death among patients with valve-in-valve-TAVI was 2.4% (95% CI: 1.0% to 5.0%) and 2.7% (95% CI: 2.3% to 3.1%) in patients with native-valve-TAVI, respectively. Correspondingly, the cumulative 5-year risk of death was 42.5% (95% CI: 34.2% to 50.6%) and 44.8% (95% CI: 43.2% to 46.4%), respectively. In multivariable Cox proportional hazard analysis, valve-in-valve-TAVI was not associated with a significantly different risk of death at 30 days (Hazard ratio (HR)= 0.95, 95% CI 0.41-2.19) and 5 years (HR=0.79, 95% CI 0.62-1.00) post-TAVI compared with native-valve-TAVI.<br /><b>Conclusions</b><br />TAVI in a failed surgical aortic prosthesis as compared to TAVI in a native valve, was not associated with significantly different short- and long-term mortality, suggesting that valve-in-valve-TAVI is a safe procedure.<br /><br />Copyright © 2023.

<div><h4>Electrocardiographic Characteristics Fail to Predict Acute Coronary Occlusions in Out-of-Hospital Cardiac-Arrest Patients Without ST-Segment Elevation.</h4><i>Leeper B, Kern KB, Liu S, Sun X</i><br /><b>Background</b><br />A minority of out-of-hospital cardiac arrest patients have an acutely occluded coronary artery without manifesting ST-segment elevation on their post-resuscitation ECG. Identifying such patients is an issue to providing timely reperfusion therapy. We aimed to evaluate the usefulness of the initial post-resuscitation electrocardiogram in out-of-hospital-cardiac-arrest patients for selection to perform early coronary angiography.<br /><b>Methods</b><br />The study population consisted of 74 of the 99 randomized patients from the PEARL clinical trial with both ECG and angiographic data. The purpose of this study was to investigate initial post-resuscitation electrocardiogram findings from out-of-hospital cardiac arrest patients without ST-segment elevation for any association with the presence of acute coronary occlusions. Secondarily, we aimed to observe the distribution of abnormal electrocardiogram findings and survival to hospital discharge of subjects.<br /><b>Results</b><br />Initial post-resuscitation electrocardiogram findings, including ST-depression, T-wave inversion, bundle branch block, non-specific changes, were not associated with the presence of an acutely occluded coronary. Normal post-resuscitation electrocardiogram findings were associated with patient survival to hospital discharge but were not associated with the presence or absence of an acute coronary occlusion.<br /><b>Conclusions</b><br />Electrocardiogram findings cannot exclude or identify the presence of an acutely occluded coronary in out-of-hospital-cardiac-arrest patients without ST-segment elevation. An acutely occluded coronary may be present regardless of normal electrocardiogram findings.<br /><br />Copyright © 2023 Elsevier B.V.

<div><h4>Automated Assessment of Cardiac Systolic Function From Coronary Angiograms With Video-Based Artificial Intelligence Algorithms.</h4><i>Avram R, Barrios JP, Abreau S, Goh CY, ... Olgin JE, Tison GH</i><br /><b>Importance</b><br />Understanding left ventricular ejection fraction (LVEF) during coronary angiography can assist in disease management.<br /><b>Objective</b><br />To develop an automated approach to predict LVEF from left coronary angiograms.<br /><b>Design, setting, and participants</b><br />This was a cross-sectional study with external validation using patient data from December 12, 2012, to December 31, 2019, from the University of California, San Francisco (UCSF). Data were randomly split into training, development, and test data sets. External validation data were obtained from the University of Ottawa Heart Institute. Included in the analysis were all patients 18 years or older who received a coronary angiogram and transthoracic echocardiogram (TTE) within 3 months before or 1 month after the angiogram.<br /><b>Exposure</b><br />A video-based deep neural network (DNN) called CathEF was used to discriminate (binary) reduced LVEF (≤40%) and to predict (continuous) LVEF percentage from standard angiogram videos of the left coronary artery. Guided class-discriminative gradient class activation mapping (GradCAM) was applied to visualize pixels in angiograms that contributed most to DNN LVEF prediction.<br /><b>Results</b><br />A total of 4042 adult angiograms with corresponding TTE LVEF from 3679 UCSF patients were included in the analysis. Mean (SD) patient age was 64.3 (13.3) years, and 2212 patients were male (65%). In the UCSF test data set (n = 813), the video-based DNN discriminated (binary) reduced LVEF (≤40%) with an area under the receiver operating characteristic curve (AUROC) of 0.911 (95% CI, 0.887-0.934); diagnostic odds ratio for reduced LVEF was 22.7 (95% CI, 14.0-37.0). DNN-predicted continuous LVEF had a mean absolute error (MAE) of 8.5% (95% CI, 8.1%-9.0%) compared with TTE LVEF. Although DNN-predicted continuous LVEF differed 5% or less compared with TTE LVEF in 38.0% (309 of 813) of test data set studies, differences greater than 15% were observed in 15.2% (124 of 813). In external validation (n = 776), video-based DNN discriminated (binary) reduced LVEF (≤40%) with an AUROC of 0.906 (95% CI, 0.881-0.931), and DNN-predicted continuous LVEF had an MAE of 7.0% (95% CI, 6.6%-7.4%). Video-based DNN tended to overestimate low LVEFs and underestimate high LVEFs. Video-based DNN performance was consistent across sex, body mass index, low estimated glomerular filtration rate (≤45), presence of acute coronary syndromes, obstructive coronary artery disease, and left ventricular hypertrophy.<br /><br /><b>Conclusion:</b><br/>and relevance</b><br />This cross-sectional study represents an early demonstration of estimating LVEF from standard angiogram videos of the left coronary artery using video-based DNNs. Further research can improve accuracy and reduce the variability of DNNs to maximize their clinical utility.<br /><br /><br /><br /><small>JAMA Cardiol: 10 May 2023; epub ahead of print</small></div>

<div><h4>Strategies to Mitigate Emergency Department Crowding and Its Impact on Cardiovascular Patients.</h4><i>Baugh CW, Freund Y, Steg PG, Body R, Maron DJ, Yiadom MYMAB</i><br /><AbstractText>Emergency Department (ED) crowding is a worsening global problem caused by hospital capacity and other health system challenges. While patients across a broad spectrum of illnesses may be affected by crowding in the ED, patients with cardiovascular emergencies - such as acute coronary syndrome, malignant arrhythmias, pulmonary embolism, acute aortic syndrome, and cardiac tamponade - are particularly vulnerable. Because of crowding, patients with dangerous and time-sensitive conditions may either avoid the ED due to anticipation of extended waits, leave before their treatment is completed, or experience delays in receiving care. In this educational paper, we present the underlying causes of crowding and its impact on common cardiovascular emergencies using the input-throughput-output process framework for patient flow. In addition, we review current solutions and potential innovations to mitigate the negative effect of ED crowding on patient outcomes.</AbstractText><br /><br />© The Author(s) 2023.

Werner GS, Zhang B</i><br /><b>Objectives</b><br />The study aims to investigate the safety and feasibility of retrograde CTO intervention via collateral connection grade 0 (CC-0) septal channel and to identify predictors of collateral tracking failure.<br /><b>Background</b><br />Guidewire crossing a collateral channel is a critical step for successful retrograde percutaneous coronary intervention (PCI) of chronic total occlusion (CTO).<br /><b>Methods</b><br />Retrograde PCI was attempted in 122 cases of CTO with CC-0 septal collaterals from December 2018 to May 2021. A hydrophilic polymer coating guidewire was used for crossing all intended CC-0 collaterals. A multivariable logistic regression analysis was performed to identify the predictors of guidewire tracking failure via the CC-0 collaterals.<br /><b>Results</b><br />Successful guidewire tracking via CC-0 septal channel was achieved in 98 (80.3%) of 122 cases. The independent predictors of CC-0 septal channel guidewire tracking failure included well-developed non-septal collateral (OR: 5.297, 95% CI: 1.107-25.353, p = 0.037) and the ratio length of posterior descending artery (PDA) versus the distance of PDA ostium to cardiac apex ≤2/3 (OR: 3.970, 95% CI: 1.454-10.835, p = 0.007). Collateral perforation, target vessel perforation, and cardiac tamponade occurred in 5 (4.1%), 3 (2.5%), and 6 (4.9%) cases, respectively. There were no complications requiring emergency cardiac surgery or revascularization of nontarget vessel.<br /><b>Conclusions</b><br />Retrograde PCI via CC-0 septal channels with a hydrophilic polymer-coated guidewire is feasible and safe in patients with CTO. Well-developed nonseptal collaterals and short PDA length influence the procedure success and the risk of guidewire tracking failure via CC-0 septal channels.<br /><br />© 2023 Wiley Periodicals LLC.<br /><br /><small>Catheter Cardiovasc Interv: 10 May 2023; epub ahead of print</small></div>

<div><h4>Outcomes After Left Main Percutaneous Coronary Intervention in Patients With Acute Myocardial Infarction Complicated by Cardiogenic Shock (from the German ALKK PCI Registry).</h4><i>El Nasasra A, Hochadel M, Zahn R, Schneider A, ... Zeymer U, ALKK-Study Group</i><br /><AbstractText>Early revascularization therapy with percutaneous coronary intervention (PCI) has been shown to improve outcomes in patients with acute myocardial infarction (AMI) complicated by cardiogenic shock (CS). Data from consecutive patients with AMI and CS treated with PCI enrolled into the prospective Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte-PCI registry were centrally collected and analyzed. Patients were divided into 4 groups with PCI for left main (LM), 1-vessel, 2-vessel, and 3-vessel diseases. Patients\' characteristics, procedural features, antithrombotic therapies, and in-hospital complications were compared between the 4 groups. Between 2010 and 2015 a total of 2,348 consecutive patients with AMI and CS were treated by PCI in 51 hospitals, 295 for LM (15 for protected, 280 for unprotected) and single-vessel (n = 491), 2-vessel (n = 524), and 3-vessel disease (n = 1,038). Thrombolysis in myocardial infarction 3 patency of the culprit lesion after PCI was 84.3%, 84.0%, 80.8%, and 84.6% in single-vessel, 2-vessel, 3-vessel disease, and LM PCI, respectively, whereas in-hospital mortality was 27.9%, 33.9%, 46.5%, and 55.9%. Bleeding rates were low (2.0%-2.3 %) and not different between groups. In a multivariate analysis a higher age, thrombolysis in myocardial infarction flow &lt;3 after PCI, 3-vessel disease, and LM PCI were independent predictors of mortality. In conclusion, PCI of the LM is performed in about 12.5% of patients with AMI and CS and was associated with a high procedural success rate, whereas mortality is increased with LM PCI.</AbstractText><br /><br />Copyright © 2023 Elsevier Inc.

The results were anonymized and randomly presented. The AUC of each angio-FFR was compared with 2-dimensional quantitative coronary angiography (QCA) percent diameter stenosis (%DS) using a 2-tailed paired comparison of AUC.<br /><b>Results</b><br />All 5 software/methods yielded a high proportion of analyzable vessels (A: 100%, B: 100%, C: 92.1%, D: 99.5%, and E: 92.1%). The AUCs for predicting fractional flow reserve ≤0.8 for software A, B, C, D, E, and 2-dimensional QCA %DS were 0.75, 0.74, 0.74, 0.73, 0.73, and 0.65, respectively. The AUC for each angio-FFR was significantly greater than that for 2-dimensional QCA %DS.<br /><b>Conclusions</b><br />This head-to-head comparison by an independent core lab demonstrated that the diagnostic accuracy of various angio-FFR software for predicting PW-FFR ≤0.80 was useful, with a higher discrimination compared with 2-dimensional QCA %DS; however, it did not reach the diagnostic accuracy previously reported in validation studies of various vendors. Therefore, the intrinsic clinical value of \"angiography-derived fractional flow reserve\" requires confirmation in large clinical trials.<br /><br />Copyright © 2023 American College of Cardiology Foundation.

Increased uptake is associated with aneurysm expansion and adverse clinical events. The effect of endovascular aneurysm repair (EVAR) on aortic disease activity and sodium [<sup>18</sup>F]fluoride uptake is unknown. This study aimed to compare aortic sodium [<sup>18</sup>F]fluoride uptake before and after treatment with EVAR.<br /><b>Methods</b><br />In a preliminary proof-of-concept cohort study, preoperative and post-operative sodium [<sup>18</sup>F]fluoride positron emission tomography-computed tomography angiography was performed in patients with an infrarenal abdominal aortic aneurysm undergoing EVAR according to current guideline-directed size treatment thresholds. Regional aortic sodium [<sup>18</sup>F]fluoride uptake was assessed using aortic microcalcification activity (AMA): a summary measure of mean aortic sodium [<sup>18</sup>F]fluoride uptake.<br /><b>Results</b><br />Ten participants were recruited (76±6 years) with a mean aortic diameter of 57±2 mm at time of EVAR. Mean time from EVAR to repeat scan was 62±21 months. Prior to EVAR, there was higher abdominal aortic AMA when compared with the thoracic aorta (AMA 1.88 vs 1.2; p&lt;0.001). Following EVAR, sodium [<sup>18</sup>F]fluoride uptake was markedly reduced in the suprarenal (ΔAMA 0.62, p=0.03), neck (ΔAMA 0.72, p=0.02) and body of the aneurysm (ΔAMA 0.69, p=0.02) while it remained unchanged in the thoracic aorta (ΔAMA 0.11, p=0.41).<br /><b>Conclusions</b><br />EVAR is associated with a reduction in AMA within the stented aortic segment. This suggests that EVAR can modify aortic disease activity and aortic sodium [<sup>18</sup>F]fluoride uptake is a promising non-invasive surrogate measure of aneurysm disease activity.<br /><br />© Author(s) (or their employer(s)) 2023.

Abstract
<div><h4>Lipoprotein(a), Oxidized Phospholipids, and Coronary Artery Disease Severity and Outcomes.</h4><i>Gilliland TC, Liu Y, Mohebi R, Miksenas H, ... Januzzi JL, Natarajan P</i><br /><b>Background</b><br />Lipoprotein(a) (Lp[a]) and oxidized phospholipids (OxPLs) are each independent risk factors for atherosclerotic cardiovascular disease. The extent to which Lp(a) and OxPLs predict coronary artery disease (CAD) severity and outcomes in a contemporary, statin-treated cohort is not well established.<br /><b>Objectives</b><br />This study sought to evaluate the relationships between Lp(a) particle concentration and OxPLs associated with apolipoprotein B (OxPL-apoB) or apolipoprotein(a) (OxPL-apo[a]) with angiographic CAD and cardiovascular outcomes.<br /><b>Methods</b><br />Among 1,098 participants referred for coronary angiography in the CASABLANCA (Catheter Sampled Blood Archive in Cardiovascular Diseases) study, Lp(a), OxPL-apoB, and OxPL-apo(a) were measured. Logistic regression estimated the risk of multivessel coronary stenoses by Lp(a)-related biomarker level. Cox proportional hazards regression estimated the risk of major adverse cardiovascular events (MACEs) (coronary revascularization, nonfatal myocardial infarction, nonfatal stroke, and cardiovascular death) in follow-up.<br /><b>Results</b><br />Median Lp(a) was 26.45 nmol/L (IQR: 11.39-89.49 nmol/L). Lp(a), OxPL-apoB, and OxPL-apo(a) were highly correlated (Spearman R ≥0.91 for all pairwise combinations). Lp(a) and OxPL-apoB were associated with multivessel CAD. Odds of multivessel CAD per doubling of Lp(a), OxPL-apoB, and OxPL-apo(a) were 1.10 (95% CI: 1.03-1.18; P = 0.006), 1.18 (95% CI: 1.03-1.34; P = 0.01), and 1.07 (95% CI: 0.99-1.16; P = 0.07), respectively. All biomarkers were associated with cardiovascular events. HRs for MACE per doubling of Lp(a), OxPL-apoB, and OxPL-apo(a) were 1.08 (95% CI: 1.03-1.14; P = 0.001), 1.15 (95% CI: 1.05-1.26; P = 0.004), and 1.07 (95% CI: 1.01-1.14; P = 0.02), respectively.<br /><b>Conclusions</b><br />In patients undergoing coronary angiography, Lp(a) and OxPL-apoB are associated with multivessel CAD. Lp(a), OxPL-apoB, and OxPL-apo(a) are associated with incident cardiovascular events.
