EARLY IMPROVEMENT IN FLOW (LEFT VENTRICULAR STROKE VOLUME INDEX) AFTER TRANSCATHETER AORTIC VALVE REPLACEMENT IS ASSOCIATED WITH IMPROVED SURVIVAL IN LOW-FLOW AORTIC STENOSIS

Abstract

Low-flow (LF) severe aortic stenosis (AS) is an independent predictor of mortality in patients undergoing aortic valve replacement (AVR). We hypothesized that improvement in flow (left ventricular stroke volume index (SVI)) after transcatheter AVR (TAVR) would predict better clinical outcomes. All
