[A case of tricuspid infective endocarditis in a drug addict].

This report describes a successful operative case of tricuspid infective endocarditis in a drug addict. A 24-year-old man with a history of drug addiction (6 months) complained of general fatigue and high fever. Echocardiography showed a large vegetation attached to the tricuspid valve and severe tricuspid regurgitation. Blood cultures revealed septicemia due to methicillin sensitive Staphylococcus aureus. He was treated for about 1 week with intravenous antibiotics. However, subsequent severe heart failure necessitated emergency operation. The tricuspid valve was replaced with Carpentier-Edwards bioprosthesis because of severe destruction of the tricuspid valve. The postoperative course was uneventful and he has remained free from endocarditis for 15 months after surgery.
