Bailout of long-sheath tip separation during noncontrast transfemoral transcatheter aortic valve replacement

Year: 2026

Type: article

Abstract: Long introducer sheaths may facilitate transfemoral transcatheter aortic valve replacement (TAVR) in unfavorable iliofemoral or aortic anatomy by reducing interaction with diseased vascular segments.1 However, calcified or narrowed access can transfer stress to the sheath tip or transition zone. Noncontrast planning in chronic kidney disease or severe contrast allergy further limits precise luminal assessment.2 Sheath disruption during TAVR has been reported with expandable sheaths,3,4 and sheath-tip fracture also has been described during endovascular aneurysm repair.
