Leiomyosarcoma--an unusual cause of right ventricular outflow tract obstruction.
A 76-year-old female patient was admitted with progressive dyspnea on exertion, signs of right ventricular failure, and severe pulmonary stenosis. Intraoperatively an infiltrating right ventricular outflow tract (RVOT) tumor was found and xenograft conduit replacement was performed successfully. Histological examination revealed primary cardiac leiomyosarcoma, the patient was discharged and is in good health condition at 9 months' follow-up. Unusual causes of RVOT obstruction should be considered.
