Abstract

The purpose of this study is to compare the late outcome of aortic valve replacement with or without preoperative coronary artery disease, and with or without coronary artery bypass. Between 2014 and 2015, 291 patients underwent aortic valve replacement. Average follow-up term was 2.5 ± 2.2 years. The retrospective comparative study was performed between the patients with (n = 115) or without (n = 176) preoperative coronary artery disease (Study 1) and with (n = 93) or without (n = 198) coronary artery bypass grafting (Study 2). Study 1: male patients were more, and diabetes was more in the patients with coronary artery disease. Long-term survival rate was significantly low in the patients with coronary artery disease (p = 0.0002 by log rank test). Freedom from repeat coronary revascularization rate was lower in the patients with coronary artery disease (p = 0.02 by log rank test). Study 2: operation time (419 ± 130 vs 290 ± 101; p = 0.0001) was longer in the patients with coronary artery bypass grafting. Improvement of ejection fraction at follow-up was more in the patients with coronary artery bypass(114 ± 43 vs 104 ± 26%; p = 0.03). Long-term survival rate and freedom from major adverse cardiac event rater were not different with or without coronary artery bypass grafting (p = 0.26 and p = 0.59, respectively, by log rank test). Although prevalence of coronary artery disease inversely affected the long-term outcome of the aortic valve replacement, simultaneous coronary artery bypass did not. Aggressive simultaneous coronary revascularization would be important to improve the long-term outcome of aortic valve replacement.
