Case Report of Melody Valve Placement to Treat Neoaortic Valve Stenosis in an Adult With Fontan Circulation.

The Melody valve (Medtronic) is commonly used for pulmonary valve replacement in patients with dysfunctional right ventricle to pulmonary artery conduits or bioprosthetic pulmonary valves. Rare reports exist of its use in the aortic position, including only 1 prior description of its use in a patient with hypoplastic left heart syndrome. We describe a 31-year-old patient with hypoplastic left heart syndrome who had severe neoaortic valve stenosis and moderate regurgitation that was successfully treated with percutaneous Melody valve placement in the neoaortic position.
