Abstract:
Papillary fibroelastoma is a rare, benign cardiac tumor. Surgical resection is indicated to prevent embolization. We herein report a case of a 78-year-old asymptomatic man who was found to have a mobile left ventricular papillary fibroelastoma anchoring deep in the left ventricle by incidental transthoracic echocardiography. The tumor was resected under visualization by a video-assisted rigid endoscope with a flexible head inserted through the aortic valve into the left ventricle. Intraoperative frozen section analysis provided a pathological diagnosis of papillary fibroelastoma. The postoperative course was uneventful. This technique is recommended for the observation and resection of a tumor anchoring deep in the left ventricle and is helpful for avoiding the adverse effects of left ventriculotomy.
