Evaluation of Aortic Valve Stenosis Using Cardiovascular Magnetic Resonance Comparison of an Original Semiautomated Analysis of Phase-Contrast Cardiovascular Magnetic Resonance With Doppler Echocardiography Carine Defrance, MD; Emilie Bollache, MS; Nadjia Kachenoura, PhD; Ludivine Perdrix, MD; Nataliya Hrynchyshyn, MD; Eric Bruguière, MD; Alban Redheuil, MD, PhD; Benoit Diebold, MD, PhD; Elie Mousseaux, MD, PhD Background—Accurate quantification of aortic valve stenosis (AVS) is needed for relevant management decisions. However, transthoracic Doppler echocardiography (TTE) remains inconclusive in a significant number of patients. Previous studies demonstrated the usefulness of phase-contrast cardiovascular magnetic resonance (PC-CMR) in noninvasive AVS evaluation. We hypothesized that semiautomated analysis of aortic hemodynamics from PC-CMR might provide reproducible and accurate evaluation of aortic valve area (AVA), aortic velocities, and gradients in agreement with TTE. 2 2 Methods and Results—We studied 53 AVS patients (AVA =0.87±0.44 cm ) and 21 controls (AVA =2.96±0.59 cm ) TTE TTE who had TTE and PC-CMR of aortic valve and left ventricular outflow tract on the same day. PC-CMR data analysis included left ventricular outflow tract and aortic valve segmentation, and extraction of velocities, gradients, and flow rates. Three AVA measures were performed: AVA based on Hakki formula, AVA based on continuity equation, CMR1 CMR2
