Prognostic Value of Myocardial Contraction Fraction for One-Year Cardiac Death After Transcatheter Aortic Valve Implantation in Severe Aortic Stenosis: A Simple Echocardiographic Metric for High-Risk Stratification

OBJECTIVE: Myocardial contraction fraction (MCF) is a volumetric index of myocardial shortening that relates left ventricular stroke volume to myocardial volume. In patients with severe aortic stenosis (AS), left ventricular ejection fraction (LVEF) may remain preserved despite a...
