Representative cases with and without conduction damage after transcatheter aortic valve implantation superior panels demonstrate a case with left bundle branch block after implantation of Sapien 3. Representative cases with and without conduction damage after transcatheter aortic valve implantation superior panels demonstrate a case with left bundle branch block after implantation of Sapien 3. The virtual basal ring plane (white-dotted line) is located inferior to the membranous septum (white star), and the valve is implanted relatively deeper to the virtual basal ring. Inferior panels demonstrate a case without conduction damage after implantation of Sapien 3. The virtual basal ring plane (white-dotted line) is located superior to the membranous septum (white star), and the valve is implanted approximately at the level of the virtual basal ring. Significant distance is noted between the inferior edge of the valve and the crest of the muscular ventricular septum, where the proximal left bundle branch ramifies from the branching portion of the bundle of His (compare to figure 2).
