- Brief Summary
A Prospective, Multicenter, Non-Randomized, Single-Arm, Open-Label Clinical Study to Demonstrate the Safety and Effectiveness of the ShortCut™ device for splitting bioprosthetic aortic valve leaflets in patients who are presented for a valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) procedure for an approved ViV indication, and who are at risk for TAVR-induced coronary artery ostium obstruction.
