Summary

In the first head-to-head randomized comparison of two devices used for transcatheter aortic valve replacement in high-risk patients with severe aortic stenosis, a balloon-expandable transcatheter valve was found to have a higher rate of device success than a self-expanding valve. This article discusses data from the Comparison of Transcatheter Heart Valves in High Risk Patients With Severe Aortic Stenosis: Medtronic CoreValve Versus Edwards SAPIEN XT trial [CHOICE; Abdel-Wahab M et al. JAMA 2014].
