A Rare Case Report of Left Atrial Angiosarcoma

The most primary cardiac tumors are benign, and malignant tumors comprise about 25%. Primary cardiac angiosarcoma is the most common malignant tumor and aggressive tumor with a high incidence of metastatic spread. The diagnosis is often delayed because of the nonspecific clinical presentation. Cardiac angiosarcoma usually arises from the right atrium. We report an extremely rare case of primary angiosarcoma originating from the left atrium in a 57-year-old woman that had been referred with a onemonth history of exertional dyspenea. Transesophageal echocardiography showed a large mass on the left atrial that protrude through mitral valve. The tumor was resected successfully with curative intent. The patient underwent adjuvant chemotherapy. We have no problem up to now in six months follow-up.
