In-hospital mortality was 51.2% (N = 21); eight (19.5%) patients had postoperative myocardial infarction (MI) and 11 (26.8%) had a major neurological event.

Abstract

: Coronary Artery Bypass Grafting (CABG) is sometimes necessary in acute Type A Aortic Dissection (AAAD) repair. The aim of this study is to analyze the incidence, indications and influence in-hospital outcomes of AAAD repair requiring concomitant CABG in a high-volume single-center experience. Retrospective study of all consecutive AAAD patients. Those who underwent concomitant CABG were identified. Preoperative, intraoperative, postoperative and follow-up data were collected and analyzed. Between January 1, 2010 and December 31, 2016, 382 patients underwent emergency surgery for AAAD. Forty-one (10.7%) underwent concomitant CABG. In this group, mean age was 64 ± 14 years, 32 were male (78%). Indication for CABG was coronary dissection in 28 patients (68.3%), post-cardiopulmonary bypass (CPB) right heart failure in 7 (17.1%), post CPB left heart failure in (7.3%) and native coronary pathology in 3 (7.3%). In 33 (80.5%) one graft was needed, in 7 (17%) two were performed and in 1 patient (2.4%) 3 were necessary. The right coronary artery (RCA) was the only revascularized vessel in 26 cases (63.4%), the left coronary artery (LCA) alone in 11 (26.8%), and both coronary systems in 4 (9.8%). In-hospital mortality was 51.2% (N = 21); eight (19.5%) patients had postoperative myocardial infarction (MI) and 11 (26.8%) had a major neurological event. Multivariable logistic regression identified concomitant CABG as a predictor of in-hospital mortality (Odds Ratio (OR) = 3.8115, 95% CI= 0.514-2.138, p = 0.001). In our study, concomitant CABG was performed in 10.7% of AAAD repair surgery and it was associated with high in-hospital mortality.
