RESUMO
A 76-years-old woman was admitted with a left ventricular tumor that was accidentally found by a transthoracic echocardiogram. The tumor was located in the papillary muscle near the apex, had an irregular surface, and was well mobile. The urgent operation was planned because the tumor might have caused of embolism. A cardiopulmonary bypass was established with distal ascending aortic cannulation and bicaval venous cannulations. The resection of the tumor was performed by a transaortic approach. Pathological examination confirmed the tumor as primary papillary fibroelastoma. During the operation, a thoracoscope was used to assist the resection of the tumor. It was useful for a good visualization in the left ventricle. In this case report we describe a rare case of primary papillary fibroelastoma in the left ventricle and a technique of resection using a transaortic approach with an assistance of a thoracoscope.
