We report a case of tricuspid infective endocarditis with peripheral pulmonary artery aneurysm. A 31-year-old man with a history of intravenous drug abuse was admitted to our institution. Echocardiography showed severe tricuspid valve insufficiency and large vegetation（10mm）attached to the tricuspid valve. Computed tomography（CT）revealed a right peripheral pulmonary artery aneurysm. We operated because of the large amount of vegetation. Before the operation, we performed coil embolization for peripheral pulmonary aneurysm. During the operation, we removed the posterior leaflet with vegetation, and performed tricuspid valve repair. The postoperative course was uneventful. Postoperative echocardiography did not show any tricuspid valve insufficiency or vegetation.
