[Third Tricuspid Valve Replacement:Report of a Case].

ABSTRACT

A 79-year-old man underwent tricuspid valve replacement (TVR) with a bovine pericardial bioprosthesis, Carpentier-Edwards Perimount (CEP), for tricuspid regurgitation 27 years earlier. Twenty-one years after the first operation, he underwent re-TVR with a bovine pericardial bioprosthesis, Magna Mitral Ease, due to prosthetic valve dysfunction. Since the prosthetic valve dysfunction progressed again, the third TVR was performed six years after the second operation. The findings of the resected bioprosthesis showed sclerosis of the septal cusp, and pannus formation between the septal and posterior cusps. For the third TVR, the porcine bioprosthesis Epic was used. Neither transvalvular nor perivalvular leakage was observed postoperatively, and the patient was discharged without any complications.
