Figure 2: (a) Balloon sizing of the bioprosthetic valve with a 25 mm × 3 cm sizing balloon, demonstrating a minimum balloon diameter of 14.6 mm. The guide wire is advanced through the Fontan fenestration, across the bioprosthetic tricuspid valve and neo-aortic valve, and placed in the descending aorta. (b) The Melody valve mounted on a 22 mm Ensemble delivery system implanted in the tricuspid position. A right ventriculogram after Melody valve implantation and postdilatation with a 22 mm Atlas Gold balloon (c) shows that the Melody valve is proximal to the bioprosthetic valve ring and extends slightly beyond the radiopaque markers with mild tricuspid regurgitation
