19 Aortic valve replacement for severe aortic stenosis with low ejection fraction

In patients with severe aortic stenosis (AS) requiring aortic valve replacement (AVR), a reduced pre-operative left ventricular ejection fraction (LVEF) is one of the most meaningful risk indicators of early and late mortality. 1 Despite this fact, AVR seems to be beneficial in the majority of patients with low LVEF. 2 From 2009 to 2016, we performed 304 cases of isolated AVR for severe AS. Among them, the patients with LVEF Although low LVEF is a predictor of increased mortality for patients with AS, our experience showed acceptable outcomes compared with the previously reported literature.
