Abstract

A replacement heart valve prosthesis for transcatheter repair of a native valve, the replacement heart valve comprises a valve construct mounted to the exterior surface of an expandable frame. The frame comprises an expandable region near the distal end of the frame, and a cusp region near the proximal region comprising a plurality of valve attachment features. The valve construct may be attached to the valve construct at least at the valve attachment features. The replacement heart valve prosthesis of present disclosure may be a more durable and long-lasting valve that has added benefits by placing valve tissue between the expandable frame and native cardiac tissue.
