The present study was designed to test the hypothesis that low-ejection fraction (EF), low-gradient aortic stenosis (AS) is a predictor of major morbidity after aortic valve replacement (AVR). We retrospectively analyzed prospectively collected data from 597 consecutive patients with AS (mean age 72 ± 11 years) who had undergone AVR or combined AVR and coronary artery bypass grafting (CABG) from 1998 to 2006 (EF ≤30% in 73 [12%]). The outcome measures included hospital mortality, major complications, and long-term survival. The overall hospital mortality rate was 4% (low-EF AS 5%; low-EF AS plus CABG 8%; AS controls 4%; AS plus CABG…
