ECHOCARDIOGRAPHIC/CATHETERIZATION DISCORDANCE IN LOW VS. HIGH GRADIENT AND LOW VS. NORMAL FLOW AORTIC STENOSIS

Discordance between echocardiography (ECHO) and catheterization (CATH) hemodynamic parameters in with aortic stenosis (AS) is well described. It is assumed to be similar regardless of flow state determined by ECHO stroke volume index (SVI) and CATH cardiac index (CI) or mean gradient (MG). We sought
