Self-Expanding Supraannular Valve Superior to Balloon-Expandable Valve for Bioprosthetic-Valve Dysfunction in Severe Aortic Stenosis With Small Aortic Annulus
1. In this randomized controlled trial, a self-expanding supra-annular valve was superior to a balloon-expandable valve for bioprosthetic-valve dysfunction among patients with severe aortic stenosis (AS) and a small aortic annulus. 2. The self-expanding valve was...
