Balloon aortic valvuloplasty in high risk aortic stenosis patients with left ventricular ejection fractions <20%.

Objectives: To determine outcomes following balloon aortic valvuloplasty (BAV) in aortic stenosis (AS) patients with a left ventricular ejection fraction (LVEF) <20%.

Background: Severe AS patients with a LVEF <20% are excluded from United States (U.S.
