ABSTRACT
BACKGROUND:
Ascending aorta replacement can be performed safely in high-volume centers. What remains unknown is whether concomitant coronary revascularization with bypass grafting affects postoperative outcomes.METHODS:
This study retrospectively reviewed a prospectively maintained institutional database for patients who underwent ascending aorta replacement (AAR) during the period from 1997 to 2018. Patients were stratified into AAR alone (AAR) vs AAR and coronary artery bypass graft (AAR with CABG), further categorized as 1 or more than 1 CABG. Aortic dissection and root replacement cases were excluded. The primary end point consisted of major adverse events (MAE), including operative mortality, perioperative myocardial infarction, stroke, need for tracheostomy, and need for dialysis. Secondary end points were operative mortality, each MAE component, and late survival.RESULTS:
A total of 951 patients were included in the analysis; 725 (76.2%) underwent isolated AAR, and 226 (23.8%) underwent AAR with CABG. Operative mortality was similar across the 2 groups (1.8% for AAR with CABG and 0.8% for AAR; P = .40). The unadjusted incidence of MAE was higher in the AAR with CABG group (5.8% vs 1.9%; P = .005).). On multivariable analysis, the performance of 1 CABG (odds ratio [OR], 1.90; 95% confidence interval [CI], 0.67 to 5.33; P = .23) and more than 1 CABG (OR, 2.65; 95% CI, 0.93 to 7.53; P = .07) was not associated with higher rates of MAE. Preoperative pulmonary dysfunction (OR, 2.51; 95% CI, 1.07 to 5.85; P = .03) was the only independent predictor of MAE.CONCLUSIONS:
In patients undergoing concomitant CABG with AAR, the performance of concomitant CABG is not associated with an increased risk of MAE.
