Transcatheter aortic valve replacement (TAVR) for severe native aortic valve stenosis (native-TAVR) and valve-in-valve TAVR by balloon-expanding and self-expanding platforms is available.1,2 Studies report post-TAVR mean gradients (MG) obtained by aortic valve continuous wave Doppler on echocardiography (echocardiography MG,4V22), without adjusting for noninvasive mean pressure recovery (PRmean) or left ventricular outflow tract MG (LVOT MG,4V12), or invasive MG (catheterization MG) comparison
