Cardiac papillary fibroelastoma is a rare primary cardiac tumor arising from any part of the endocardium. In particular, papillary fibroelastoma originating from the mitral valve chordae is very rare. A 66-year-old man was hospitalized for a left ventricular tumor. Echocardiography revealed a high echoic mass of the mitral valve chordae with grade I mitral regurgitation. Under cardiopulmonary bypass, we performed excision of the mass and the marginal chordae of the mitral valve, and decided there was no need of valvuloplasty. Pathological diagnosis indicated the tumor was papillary fibroelastoma. The postoperative course was uneventful and echocardiography showed no progression of mitral valve regurgitation.
