Impact of Stroke Volume Index and Left Ventricular Ejection Fraction on Mortality After Aortic Valve Replacement

Objective To assess the impact of stroke volume index (SVI) and left ventricular ejection fraction (LVEF) on prognosis in patients with severe aortic stenosis, comparing those undergoing transcatheter aortic valve replacement (TAVR) and those with surgical AVR (SAVR). Patients and Methods A total of 742 patients from the CoreValve US Pivotal High-Risk Trial randomized to TAVR (n=389) or SAVR (n=353) from February 2011 to September 2012 were...
