Abstract:
Transcatheter aortic valve replacement (TAVR) via the transfemoral (TF), transapical (TA), or even the transaortic (TAO) approach in high-risk or inoperable patients is quickly becoming a safe and effective modality for the treatment of symptomatic severe aortic stenosis (AS). However, in this selected group of patients, those with anatomical or physiologic constraints preventing TF, TA, and conventional TAO TAVR, alternative sites of access must be explored. Here, we report a successful TAVR in an inoperable patient with severe AS using a distal abdominal TAO approach via a synthetic graft-conduit.
