Trans-aortic excision of intraventricular lipoma with the assistance of arthroscopic camera.

Cardiac lipomas are extremely rare benign neoplasms of the heart. We report the case of a 64-year-old female complaining of rapidly worsening dyspnea and lower limb edema. Echocardiograms showed a large hyperechoic mass which occupied the left ventricle. The cardiac nuclear magnetic resonance allowed the diagnosis of the left ventricular tumor of lipoma or liposarcoma. The tumor was resected through the ascending aorta, without injuring neither the aortic valve nor the left ventricle. Histological diagnosis showed that the tumor was a lipoma. The patient had an uneventful recovery, with no recurrence two years later.
