Percutaneous Pulmonary Valve Implantation in the Patched Right Ventricular Outflow Tract 51 Years after Surgical Repair for Tetralogy of Fallot.

Percutaneous pulmonary valve implantation (PPVI) has become a widely practiced treatment option for patients with right ventricular outflow tract (RVOT) dysfunction. For this procedure, the Melody transcatheter pulmonary valve has become the most widely used system. On-label indications are limited to the treatment of failing circumferential conduits. However, there is growing but still limited experience with the off-label treatment of native or patched RVOTs. Here, the case is reported of a 57-year-old patient in whom redo-surgery for a dysfunctional pulmonary valve could be avoided by PPVI into the patched RVOT at 51 years after tetralogy of Fallot repair.
