A 25-year-old man with a previous diagnosis of congenital bicuspid aortic valve presented with a fever of unknown origin for 3 months. Transthoracic echocardiography revealed vegetation on the mitral valve leaflet. Transesohageal echocardiography revealed severe aortic regurgitation and a mitral valve leaflet aneurysm. Despite intensive antibiotic therapy, his clinical condition did not improve, so he underwent aortic and mitral valve repair. The aortic valve was shown to be unicuspid intraoperatively. We made a new commissure, then mitral valve aneurysm was resected and a new leaflet was made using the pericardium. There was almost no regurgitation seen on postoperative echocardiography.
