Abstract

Transcatheter aortic valve replacement (TAVR) was developed for prohibitive/high-risk severe aortic stenosis (AS), with early randomized trials confirming efficacy in older, high-risk patients (1, 2). While transfemoral (TF) access is feasible in most patients, 5–10% have anatomy precluding safe delivery (3), making alternative access an essential consideration and the focus of this review. An overview of intra-thoracic and extra-thoracic alternative access routes for TAVR is shown inSupplemental Figure S1, with the decision pathway summarized in Figure 1.
