Image Description
Cardiac sarcomas, in general, are quite rare; however, they make up almost 95% of all primary malignant tumors of heart. The most common primary cardiac sarcoma is angiosarcoma, followed by synovial sarcoma and leiomyosarcoma.
The most common location for cardiac angiosarcoma is the right atrium. They may bulge into the right atrial chamber or invade the myocardium, tricuspid valve, or vena cava. Less common sites include the left atrium, right pericardium, and the ventricles. Rare cases have occurred in association with mitral or aortic valvular prostheses (Dacron).
