Transcatheter Aortic Valve Implantation for Patients with Smaller Anatomy.

Transcatheter aortic valve implantation (TAVI) has reached relative maturity for the treatment of severe, symptomatic aortic stenosis (AS). TAVI for patients with smaller anatomy is a challenging procedure due to specific anatomical difficulty and complications including annulus rupture and vascular complications. Prevention of these complications, and the introduction of a newer-generation and lower-profile TAVI system, will encourage the prevalence of TAVI for patients with smaller anatomy.
