[Surgical Treatment of Papillary Fibroelastoma Developed in the Left Ventricle]

Papillary fibroelastomas are rare benign cardiac tumors, which generally arise from the valvular endocardium. Although they have little hemodynamics effects, they can cause some life threatening events such as cerebral embolization. We herein report a case of 68-year-old female with a mobile left ventricular mass of 10 mm in diameter. It was accidentally found on the anterior papillary muscle by echocardiography under evaluation of the angina pectoris. Resection of the left ventricular mass was performed through the mitral valve. Coronary artery bypass grafting to left anterior descending artery was also performed using the left intra-thoracic artery. Pathological finding of the tumor was papillary fibroelastoma. Post-operative course was uneventful, with no recurrence about a year.
