Axillary artery as alternative access for transcatheter aortic valve implantation in a patient with thoracic and abdominal multilayer flow modulator stents, and in a patient with occluded bilateral carotid and iliac arteries.

Abstract

Transaxillary access is an alternative to femoral access in patients with iliofemoral occlusion for transcatheter aortic valve implantation (TAVI). A Multilayer Flow Modulator (MLFM) stent is frequently used in patients with a complex thoracic and abdominal aortic aneurysm. The MLFM stent is particularly used in cases where large arteries, such as the renal or celiac artery, feed from the aneurysmal sac. To the best of our knowledge, there is no prior report in the literature of a TAVI case with a pre-existing MLFM stent. Presently described are 2 TAVI cases, one with thoracoabdominal MLFM stents, and the second with occluded bilateral carotid and iliac arteries.
