SU-C-18C-02: Specifcation of X-Ray Projection Angles Which Are Aligned with the Aortic Valve Plane From a Planar Image of a Valvuloplasty Balloon Inflated Across the Aortic Valve

Purpose: Transcatheter aortic valve replacement (TAVR) procedures provide a method to implant a prosthetic aortic valve via a minimallyinvasive, catheter‐based procedure. TAVR procedures require use of interventional fluoroscopy c‐arm projection angles which are aligned with the aortic valve plane to minimize prosthetic valve positioning error due to x‐ray imaging parallax. The purpose of this work is to calculate the continuous range of...
