Predicting Paravalvular Regurgitation Following Transcatheter Valve Replacement: Utility of a Novel Method for Three-Dimensional Echocardiographic Measurements of the Aortic Annulus

Using a novel approach to 3DE annular measurements, 3DE AveAnnDiamP and 3DE AveAnnDiamA can be reliably measured and correlate best with post-TAVR PVR area. New sizing algorithms with 3DE measurements should be developed.
