Abstract:
Percutaneous pulmonary valve implantation has been established as a valuable treatment option for elder children and adolescents with conduit failure in the right ventricular outflow tract. Transcatheter valve implantation in the tricuspid position is restricted to single case reports. A 26-year-old male initially diagnosed with tetralogy of Fallot and hypoplastic pulmonary arteries hitherto underwent a total of five open chest procedures including tricuspid valve replacement with a bioprosthesis and a pulmonary homograft exchange. He now presented with severe right heart failure due to a degenerated pulmonary homograft and calcified, severely stenotic tricuspid bioprosthesis with markedly dilated and reduced right ventricular function. We report on the first successful percutaneous transcatheter double-valve replacement using two Melody valves in the pulmonary and tricuspid position, respectively.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
