Abstract:
Transcatheter pulmonary valve implantation is established as a valuable option to reconstruct failing right ventricular outflow tract function. Percutaneous tricuspid valve-in-valve or valve-in-ring reconstruction is even applied with increasing acceptance. A 46-year-old woman with a diagnosis of carcinoid-dependent right heart failure underwent surgical bioprosthetic tricuspid and pulmonary valve replacement. Almost 1 year later, she presented again with markedly dilatated and reduced right heart function caused by degeneration of both biologic valves. We report a successful two-stage percutaneous transcatheter double-valve replacement with the use of a Melody valve in pulmonary and tricuspid positions.
