SAFETY AND EFFICACY OF USING PRESSURE WIRE WITH DOBUTAMIN INFUSION IN THEMOYNAMIC ASSESSMENT OF LOW FLOW LOW GRADIENT AORTIC STENOSIS

Background: 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. Dobutamine Challenge is recommended...
