Primary Pulmonary Valve Leiomyosarcoma in a 35-Year-Old Woman
Abstract:
Primary cardiac leiomyosarcomas are rare, with a high incidence of local recurrence. Herein, we report the case of a 35-year-old woman who was admitted with right ventricular failure and suspected pulmonary embolism. Upon echocardiography, we detected a mass in the pulmonary trunk that involved the pulmonary valve and led to valvular stenosis. The optimal protocol for treating these tumors is as yet unclear. Complete resection can rarely be achieved. However, palliative surgery is usually undertaken because many patients present with mechanical obstruction, such as significant pulmonary stenosis.
