Description
Akihiko Sato and co-authors report a rare accident during a transcatheter aortic valve procedure. An eighty-year-old woman with severe valve narrowing received a self-expanding valve through the leg artery. After placement, pressure readings showed the valve was not working, and ultrasound found a tube-like structure blocking its leaflets from opening.
The culprit was a strip of the iliac artery's inner lining, torn loose like an endarterectomy specimen during delivery and trapped inside the valve. Her artery had been heavily calcified before the procedure. Balloon widening was tried to free the leaflets. The case warns valve teams that vessel tissue itself can jam a fresh implant. Heart teams get a failure mode to watch for in calcified access routes.
