INFLUENCE OF FLOW AND VELOCITY PROFILE ON INCONSISTENCY IN ECHOCARDIOGRAPHIC AORTIC VALVE STENOSIS ASSESSMENT: A COMPUTED TOMOGRAPHY AND COMPUTATIONAL FLOW DYNAMICS STUDY

Significant inconsistencies have been reported in the assessment of aortic valve (AV) stenosis (AS) between echocardiographic and other techniques. We have observed that some patients have an AV area (AVA) > 1cm2 using direct planimetry on computed tomography angiography (CTA) despite a peak
