600.08 3-Dimensional Printing Could Help Prevent Paravalvular Leak After Transcatheter Aortic Valve Replacement

Paravalvular leak (PVL) carries a high morbidity and mortality after transcatheter aortic valve replacement (TAVR), but there is no effective method to predict PVL prior to valve implantation. Using pre-TAVR computed tomography (CT) scans, 3-dimensional (3D) aortic root models were printed for 16
