Abstract

Coronary artery obstruction is a life-threatening complication of transcatheter aortic valve replacement procedures, and current preventive strategies are suboptimal. The novel ShortCut device splits bioprosthetic valve leaflets that are at risk of causing coronary artery obstruction after transcatheter aortic valve implantation, allowing for normal coronary flow. In this video tutorial, we demonstrate a valve-in-valve transcatheter aortic valve implantation using a dedicated leaflet-splitting device for prevention of coronary artery obstruction in transcatheter aortic valve replacement.
