[Surgical treatment of right atrial papillary fibroelastoma, originated from the eustachian valve--a case report].

Papillary fibroelastoma is one of the most common benign primary cardiac tumor after myxoma. However, it is rare to originate from Eustachian valve. A 44-year-old woman was pointed out the right atrial tumor during admission for vasospastic angina. On two-dimensional echocardiogram, the tumor was found in the right atrium, and easily moved to the right ventricle. At operation, the tumor originated from Eustachian valve, and was resected together with the valve by means of extracorporeal circulation. The size of tumor was 57 mm in length, and the histological diagnosis was papillary fibroleastoma. The post-operative course was uneventful.
