CRT-800.10 Safety and Efficacy of Pressure Wire Use in Hemodynamic Assessment of Paradoxical Low Flow Low Gradient Aortic Stenosis

Current guidelines discourage aortic stenosis (AS) evaluation by direct pressure measurement if echocardiography (echo) is adequate. However several studies show sizable differences between echo and catheterization (cath) lab measurements. Low flow/ low gradient (LF/LG) severe aortic stenosis...
