Abstract

BACKGROUND:

Aortic valve replacement with coronary artery bypass graft surgery is currently the standard therapy for patients with aortic stenosis and concomitant coronary artery disease. We sought to determine whether transcatheter aortic valve implantation combined with percutaneous coronary intervention might be an equivalent strategy.

METHODS:

A total of 243 high-risk patients (Society of Thoracic Surgeons [STS] score >10% and/or European System for Cardiac Operative Risk Evaluation [EuroSCORE] >15%) presenting with aortic stenosis with concomitant coronary artery disease were studied. Patients were treated either by surgical aortic valve replacement combined with coronary artery bypass graft (group 1, n = 184) or by percutaneous coronary intervention within 12 months before transapical or transfemoral transcatheter aortic valve implantation (group 2, n = 59). A propensity score adjusted regression analysis was used to compare 30-day mortality as the primary study endpoint between the groups.

RESULTS:

Group 1 mean age (75 ± 6 years), EuroSCORE (18.1% ± 13.8%), and STS score (13.1% ± 8.7%) were significantly different from group 2 (mean age 80 ± 6 years, EuroSCORE 27.5% ± 16.3%, and STS score 16.7% ± 10.5%; p < 0.001). Thirty-day mortality was 12.5% in group 1 compared with 11.9% in group 2 (odds ratio 0.94, 95% confidence interval: 0.38 to 2.32, p = 0.89). Univariate analysis revealed left ventricular ejection fraction, pulmonary hypertension, renal insufficiency, STS score, EuroSCORE, and previous cardiac surgery as predictors for 30-day mortality (p < 0.05). Risk-adjusted multivariate regression analysis showed only left ventricular ejection fraction to be strongly associated with 30-day mortality and confirmed no significant difference between the groups (p = 0.44). To further control for study bias, a 10-layer propensity score model based on the univariate analysis again indicated equivalence regarding the primary endpoint (p = 0.33).

CONCLUSIONS:

The present study demonstrates that transcatheter aortic valve implantation in combination with prior percutaneous coronary intervention within 12 months produces similar results in a propensity score matched high-risk patient population.
