[Primary cardiac angiosarcoma in the left atrium with adrenal metastasis; report of a case].

We encountered a 61-year-old woman with primary cardiac angiosarcoma in the left atrium. On echocardiography, the tumor extended into the atrial septum and mitral valve, and mitral valve stenosis and regurgitation were significant. We resected the tumor protruding into left atrium, and affecting mitral valve. The surgical procedure was not radical, but on postoperative echocardiography, function of the mitral valve was improved. Three months later, elevation of her right diaphragma was observed on chest X-ray and a giant adrenal tumor was detected by magnetic resonance imaging. Tumor biopsy indicated that this tumor was adrenal metastasis from cardiac angiosarcoma. In addition, echocardiography showed the recurrence of angiosarcoma in the left atrium and the presence of mitral stenosis and regurgitation. She died of heart failure 185 days postoperatively.
