Papillary fibroelastoma in the right ventricular outflow tract: a case report]

A 60-year-old female was admitted to our hospital for further examination of heart murmur. Chest radiography revealed cardiomegaly and pulmonary congestion. Two-dimensional echocardiography showed a mobile and pedunculated mass, approximately 20 mm in diameter, attached to the right ventricular outflow tract, and perimembranous ventricular septal defect. Cardiac catheterization and blood sampling were performed, which showed a pulmonary to systemic flow ratio of 3.70. She underwent surgical excision of the tumor, ventricular septal defect patch suture and tricuspid annuloplasty. Histological examination confirmed papillary fibroelastoma. The predominant location of papillary fibroelastoma is the valvular surface. This very rare case of papillary fibroelastoma was located in the right ventricular outflow tract.
