Abstract

Objective

Type A acute aortic dissection (AAD), especially that with coronary artery involvement and malperfusion, is a life-threatening disease. In the present study we aimed to investigate the association of surgical treatment and percutaneous coronary intervention (PCI) with in-hospital mortality in patients with type A AAD and coronary artery involvement.

Methods

This retrospective multicenter registry in Japan included 225 patients with type A AAD and coronary artery involvement. Treatment strategies including surgical treatment and/or PCI were left to treating physicians. The primary end point was in-hospital death.

Results

Of 225 patients, dissection extended into the right and left coronary arteries and both in 115 (51.1%), 105 (46.7%), and 5 (2.2%), respectively. Overall, 94 (41.8%) patients died during the hospitalization. Coronary angiography was performed in 53 (23.6%) patients, among whom 39 (73.6%) underwent PCI. Surgical repair was performed in 188 (83.6%) patients. In patients who received neither procedure, 33 of 35 (94.3%) died during the hospitalization. PCI was performed as a bridge to surgical repair in 37 of 39 (94.9%) patients, and in-hospital mortality of patients who underwent PCI and surgical procedures was 24.3%. Multivariable analysis identified PCI and surgical procedures as factors associated with lower in-hospital mortality rates.

Conclusions

Coronary artery involvement in type A AAD was associated with high in-hospital mortality of more than 40% in the current era. An early reperfusion strategy with PCI as a bridge to surgical repair might improve clinical outcomes in this fatal condition.

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).
