Comparison of Transcatheter Heart Valves in High Risk Patients With Severe Aortic Stenosis - CHOICE


The goal of the trial was to evaluate transcatheter aortic valve replacement (TAVR) with a balloon-expandable valve versus a self-expandable valve among high-risk patients with iliac arteries suitable for transfemoral access.

The CHOICE trial showed that a balloon-expandable valve was superior to a self-expandable valve due to a lower risk of significant aortic regurgitation and need for permanent pacemaker.
