“Cusp-Overlap” View Simplifies Fluoroscopy-Guided Implantation of Self-Expanding Valve in Transcatheter Aortic Valve Replacement

Accurate device implantation in transcatheter aortic valve replacement (TAVR) depends on: 1) obtaining a 3-cusp coplanar projection; and 2) centering delivery catheter across the valve. Unlike balloon-expandable valves, which require a coplanar projection with 3 cusps (yellow dot = non [N], green
