Perkutan indsaettelse af pulmonal stentklap

A number of congenital cardiac malformations involve the right ventricular outflow tract and are often treated with a biological valved conduit. The longevity of these valves is limited due to graft degeneration, which causes progressive valvular dysfunction and subsequently right ventricular failure. Due to the young age of these patients, repeat surgery can be expected and this has motivated the invention of the percutaneous stented valve implantation (PPVR).
