A Case of Mitral Valve Papillary Fibroelastoma Leading to Transient Ischemic Attack (TIA) / 日本心臓血管外科学会雑誌

ABSTRACT

We report a case of surgical treatment for mitral valve papillary fibroelastoma which is an uncommon and rare benign tumor. The patient was a 62-year-old woman who had TIA (paralysis of left leg) and was admitted with the diagnosis of cardiac tumor. Before operation, the tumor was detected in the left atrium two-dimensional echocardiography, attached to the anterior leaflet of the mitral valve. At operation, the tumor was 11×8mm in size, with a yellow jelly-like and fragile appearance, attached to the same position as indicated by echocardiography. As the tumor occupied over one third of the leaflet, it was excised including all the anterior leaflet of the mitral valve and a prosthetic valve was replaced leaving the posterior leaflet intact. The tumor was diagnosed as papillary fibroelastoma by pathological examination. The postoperative course was uneventful.
