[An adult case of tricuspid valve endocarditis with ventricular septal defect; report of a case].

A 50-year-old man was admitted to hospital because of an elevated fever. He had been diagnosed with ventricular septal defect in his childhood, but surgery had not been recommended. An echocardiogram showed vegetations on the tricuspid valve, severe tricuspid regurgitation and perimembranous ventricular septal defect. He was diagnosed with infective endocarditis( IE) and treated with antibiotics and diuretics. Five serious dental caries, which had probably caused IE, were found and extracted before surgery. After 4 weeks of medical treatment, we performed tricuspid valve repair and closed the ventricular septal defect. The postoperative course was uneventful. He has been free from any complication for over 3 years.
