Access Options for Transcatheter Aortic Valve Replacement in Patients with Unfavorable Aortoiliofemoral Anatomy.

Overview

In the current era, 10-15 % of transcatheter aortic valve replacement (TAVR)-eligible high and prohibitive risk patients with severe symptomatic aortic stenosis are not candidates for transfemoral arterial access. Knowledge of the various alternative access options can enable TAVR teams to provide improved quality of life and potentially life-saving treatment for a group of patients who otherwise have no viable options. In this article, we review approach to patients with unfavorable femoral arterial anatomy and provide an in-depth discussion on the various alternative routes for TAVR.
