Surgical stented transcatheter valve-in-valve implantation in atrioventricular position in children

The Melody valve (Medtronic, Minneapolis, MN, USA) is a stented bovine jugular vein graft that was primarily approved for transcatheter implantation in a pulmonary valve position. The prosthetic valve can also be implanted in an atrioventricular position in infants and young children, and in these cases it must be modified appropriately.  In this tutorial we demonstrate the surgical preparation of a stented transcatheter Melody valve for implantation in the atrioventricular position. Additionally, we present a safe and effective method for surgical valve-in-valve implantation in a 3-year-old patient with hypoplastic left heart syndrome.
