Recovery after balloon aortic valvuloplasty in patients with aortic stenosis and impaired left ventricular function: predictors and prognostic implications.

Aims: The aim of this study was to evaluate predictors of recovery after balloon aortic valvuloplasty (BAV) among patients with aortic stenosis and depressed left ventricular ejection fraction (LVEF). Predictors for recovery after BAV are not clearly defined. B-type natriuretic peptide (BNP) predicts outcome after surgical and transcatheter aortic valve replacement.
