ABSTRACT
Right-sided infective endocarditis (IE) accounts for 5% to 10% of all IE. Compared with left-sided IE, antibiotic treatment is effective in about 70% of cases. The timing of surgical treatment for right-sided IE is therefor controversial. A 26-year-old woman had suffered from tricuspid valve endocarditis with DIC. There was no evidence of any previous cardiac event or dental treatment. Echocardiography showed a large vegetation attached to the anterior leaflet of tricuspid valve with moderate tricuspid regurgitation. We removed the vegetation with a part of the anterior leaflet and performed tricuspid valvuloplasty and annuloplasty. The patient had an uneventful postoperative course and received intravenous antibiotic treatment for a further 4 weeks.
