[Tricuspid Valve Repair in a Patient with Isolated Tricuspid Valve Infective Endocarditis with Pulmonary Embolism;Report of a Case].

We report a case of 39-year-old man who developed tricuspid valve infective endocarditis with a complication of pulmonary embolism. He was transferred to our institution because of intermittent fever and enlargement of the vegetation of the tricuspid valve in spite of optimal antibiotics treatment. Computed tomography revealed pulmonary embolism, and transesophageal echocardiography showed a large and mobile vegetation (22×10 mm) on the tricuspid valve with moderate regurgitation. In addition, Streptococcus agalactiae was identified in blood cultures. The patient underwent surgical resection of the vegetation followed by tricuspid valve repair including De Vega's annuloplasty. Antibiotic therapy was continued for 4 weeks after surgery, and he was discharged on the 31st postoperative day. No endocarditis nor tricuspid valve dysfunction has re-occurred.
