Abstract
A 45-year-old man was admitted with several histories of cerebral infarction. Transesophageal echocardiography showed a small tumor on the anterior mitral leaflet. Open heart surgery was performed. The tumor was removed including a part of the anterior mitral leaflet and mitral valve plasty was done. The post-operative course was uneventful. Papillary fibroelastoma was diagnosed pathologically. To avoid embolic complication, an early surgical procedure is recommended.
