The Edwards delivery system pusher is identified as a rare cause of potentially life-threatening Stanford type A aortic dissection during transcatheter aortic valve implantation.
1 92-year-old female with severe aortic stenosis (NYHA class III, LVEF 55%), horizontal aorta (aortic angulation 71°), and mild ascending aortic dilatation (43 mm).
Transcatheter aortic valve implantation (TAVI) using a 23-mm Sapien 3 Ultra Resilia valve via percutaneous transfemoral access.
Stanford type A aortic dissectionsafety
A horizontal aorta and ascending aortic dilatation may increase the risk of iatrogenic Stanford type A aortic dissection caused by the delivery system pusher during TAVI.
Absolute Event Rate: 0% vs 0%
Objective: Transcatheter aortic valve implantation (TAVI) is an established treatment for severe aortic stenosis. While its safety profile has improved, rare but potentially life-threatening complications persist, such as Stanford type A aortic dissection, which typically occurs during balloon dilatation, valve deployment, or stent-edge injury. However, aortic injuries caused by delivery system pusher components have rarely been reported.
