Bioprosthetic tricuspid valve stenosis is extremely rare. We report the case of a 54-year-old man with a history of infectious endocarditis (IE) and two previous tricuspid valve replacements (TVRs). The first TVR at age 25 was performed secondary to IE using a Star-Edwards Ball Valve. The repeat-TVR using a St. Jude Medical Epic bioprosthesis was performed at age 51 due to severe ball valve stenosis. Repeat surgical valve replacement is an extremely high-risk procedure. Percutaneous transcatheter tricuspid balloon valvuloplasty (PTTBV) is an acceptable treatment option for symptomatic severe tricuspid valve stenosis. There have been few reports of successful PTTBV performed after bioprosthetic TVR. Successful treatment with PTTBV for bioprosthetic tricuspid valve stenosis was achieved without complications in this patient. We believe that PTTBV can be performed either as a destination therapy or as a bridge to TVR.
