Why the study?
Coronary artery obstruction is a life-threatening complication of transcatheter aortic valve replacement procedures, and current preventive strategies are suboptimal.
The ShortCut leaflet-splitting device offers a novel technique to prevent life-threatening coronary artery obstruction during valve-in-valve transcatheter aortic valve replacement.
ShortCut may enable safer valve-in-valve TAVI by preventing coronary obstruction; leaves open prospective safety and efficacy trials.
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.
