[A case of tricuspid valve endocarditis in the drug addict].

We reported a case of tricuspid valve endocarditis in a drug addict. A 25-year-old woman with a history of drug abuse was admitted to our hospital for high fever. Blood cultures revealed staphylococcus aureus, and echocardiography showed vegetation attached to the tricuspid valve and moderate tricuspid regurgitation. Excision of the posterior leaflet including vegetation, and direct suture of the residual posterior leaflet along with annuloplasty was successfully done. Postoperative course was uneventful and endocarditis was eradicated.
