Surgical Mitral Valve Replacement Using a Catheter-Based MelodyTM Valve in a Landing Zone Constructed With a PTFE-Covered Expandable Cheatham-PlatinumTM Stent.

Abstract

Mitral valve replacement using a Melody valve is a promising solution to the challenge of surgical mitral valve replacement in infants with a hypoplastic annulus. We report the creation of a landing zone in the mitral valve annulus using a Cheatham-Platinum (CP)-covered stent that facilitates Melody valve placement, helps prevent paravalvular leak, minimizes left ventricular outflow tract obstruction, and allows for potential future dilation of the valve.
