    Highlights

    • Low Ejection Fraction <35% is the strongest predictor of 1 year mortality after transcatheter valve replacement.
    • Stroke Volume Index, transaortic flow gradient, and Aortic valve area do not predict mortality as well.
    • Ejection fraction may help in risk stratification and selection of patients undergoing transcatheter valve placement

    Abstract

    Background

    Transaortic flow, maximum velocity (V max), mean gradient (MG), left ventricular ejection fraction (LVEF), Aortic valve area (AVA) and dimensional index (DI) are important determinants of prognosis in patients with severe aortic stenosis. The specific role of these echocardiography-derived values in predicting prognosis of severe aortic stenosis patients undergoing Transcatheter aortic valve replacement (TAVR) is less defined.
