Papillary fibroelastoma is a rare benign cardiac tumor generally arising from the valvular endocardium. We describe the successful surgical management of a patient who had a papillary fibroelastoma attached to a false tendon of the left ventricle. A 71-year old man was admitted with a left ventricular tumor. Routine transthoracic echocardiography revealed a mobile, 6×8mm mass, which was attached to a false tendon in the apical area of the left ventricle. Continuous intravenous heparin was commenced to avoid the embolism, and then an urgent operation was performed, consisting of left ventriculotomy following establishment of a standard cardiopulmonary bypass. A mobile gelatinous mass with a short stalk, 7mm in diameter, was attached to the false tendon. The mass was excised including a part of the false tendon. The excised tumor changed its shape in saline to a sea-anemone like tumor. The histopathological findings were consistent with the diagnosis of papillary fibroelastoma. The patient made an uneventful recovery and was discharged from the hospital on postoperative day 12.
