Complex tricuspid valve repair for infective endocarditis: leaflet augmentation, chordae and annular reconstruction

Abstract

Surgical treatment of tricuspid valve (TV) endocarditis remains a challenge because of extensive valve destruction, high risk of reinfection, poor outcomes with valve replacement and complex patient compliance issues. Reconstruction of the TV is certainly favoured over replacement; however, diffuse, multifocal vegetations and complete debridement often leave insufficient building materials necessary for repair. We describe our surgical reconstructive technique that relies upon extensive autologous pericardial patch augmentation of the destroyed TV leaflets to establish leaflet coaptation, supplemented with expanded polytetrafluoroethylene neo-chordae and annular reconstruction. We report our outcomes in a series of patients with grossly infected TVs with more than 50% of valvular destruction.
