Methods
This was a retrospective, multicenter, observational study. From January 2008, to May 2018, a total of 4230 patients were diagnosed with type A AAD and were admitted to 15 tertiary centers across Japan, collaborating with the Angina Pectoris-Myocardial Infarction Multicenter Investigators (Table E1),8,9 among whom 225 (5.3%) had coronary artery involvement. Type A AAD was defined as any dissection including intramural hematoma that involved the ascending aorta, presenting within 14 days of
Results
Of 225 patients with type A AAD and coronary artery involvement, dissection extended into the RCA, LCA, and both in 115 (51.1%), 105 (46.7%), and 5 (2.2%), respectively. During the hospitalization, 94 (41.5%) patients died. The rates of Killip class IV and cardiac arrest on admission were lower in patients who survived to discharge than their counterpart (Tables 1 and E2). Mode of surgical and percutaneous intervention is listed in Table 2, and baseline characteristics according to treatment
Discussion
The present multicenter registry data confirmed that coronary artery involvement was found in approximately 5% in patients with type A AAD and was associated with a high in-hospital mortality rate of more than 40%. CAG was performed in selected patients in 23.6%, among whom approximately three-quarters underwent PCI. Almost all PCI procedures were done as a bridge to surgical repair, resulting in better outcomes. Multivariable analysis identified PCI and surgical procedures as factors
Conclusions
The present multicenter registry showed that coronary artery involvement in type A AAD was not infrequent and was associated with high in-hospital mortality rates of more than 40%. An early reperfusion strategy with PCI as a bridge procedure to surgical repair might improve clinical outcomes in patients with type A AAD complicated with coronary artery involvement (Video Abstract).
