RESUMEN
Papillary fibroelastoma(PFE) is a rare and benign primary cardiac neoplasm. The incidence of PFE in the left ventricle is lower than that in other parts of the heart. A 67-year-old female was referred to our cardiology department for treatment of severe cardiac failure due to mitral regurgitation. Transthoracic and transesophageal echocardiography coincidently revealed a 1.0 cm highly mobile mass attached by a stalk to the outflow tract wall of the left ventricle. The mass was easily detected using endoscope and successfully removed without any postoperative complications and was pathologically diagnosed as a PFE. In this report, we discuss the echocardiographic character of PFE and the usefulness of endoscope for the identification and resection of a PFE in the left ventricle.
