TCT-454 Myocardial Fibrosis Imaging by Speckle Tracking Echocardiography Improves Risk Stratification in Severe Aortic Stenosis After Transcatheter Aortic Valve Replacement

Long-standing aortic stenosis (AS) results in fibrotic changes that often persist after transcatheter aortic valve replacement (TAVR). Fibrosis in AS preferentially affects the left ventricular (LV) basal segments and can lead to ventricular dyssynchrony. We hypothesize that basal longitudinal
