Abstract
Primary cardiac angiosarcoma is very rare. In this report, we describe an interesting case of a 25-year-old male with a giant primary angiosarcoma invading the right heart. He was urgently admitted to the hospital for respiratory distress. Once the diagnosis was suspected by chest x-ray, echocardiography, and CT scan, and given the patient's hemodynamic and respiratory instability, an emergency open-heart surgery was necessary to prevent complications. Through a right atriotomy and a pulmonary infundibulotomy, the tumor was resected. Invaded by the tumoral process, the tricuspid valve was replaced with a biological prosthesis. The postoperative course was marked by severe right ventricular dysfunction with multiorgan failure. Histopathologic examination of the surgical specimen confirmed a primary cardiac angiosarcoma.
