Abstract

The native tricuspid leaflets are sometimes preserved with tricuspid valve replacement to prevent atrioventricular block or maintain right ventricular function. However, after a tricuspid valve replacement using bioprosthetic valve, a rare complication involving adhesion of the pannus formation to the prosthetic valve may occur. We report the case of a 48-year-old woman who underwent a third tricuspid valve replacement with a bioprosthetic valve for severe tricuspid regurgitation 2.5 years after the redo tricuspid valve replacement.
