Cross-Sectional Computed Tomographic Assessment Improves Accuracy of Aortic Annular Sizing for Transcatheter Aortic Valve Replacement and Reduces the Incidence of Paravalvular Aortic Regurgitation

Study Questions:

Using the outcome measure of post-procedure paraprosthetic aortic regurgitation, what is the optimal method for aortic annulus sizing for transcatheter aortic valve implantation (TAVI)?
