Melody Valve
A transcatheter pulmonary valve replacement device consisting of a bovine jugular vein valve mounted in a balloon-expandable stent platform.
Full Definition
The Melody transcatheter pulmonary valve (Medtronic) is a revolutionary device that allows percutaneous pulmonary valve replacement without the need for open-heart surgery. The valve consists of a tri-leaflet bovine jugular vein valve sewn into a balloon-expandable platinum-iridium stent frame. It is specifically designed for patients with dysfunctional right ventricular outflow tract conduits or bioprosthetic valves, providing an alternative to surgical valve replacement. The Melody valve is delivered through a transcatheter approach via the femoral vein and can be implanted in conduits or surgical valves with appropriate landing zones. This technology has significantly reduced the lifetime burden of surgical reinterventions in patients with complex congenital heart disease requiring right heart reconstruction.
