Primary cardiac tumors are rare with an incidence ranging from 0.001% to 0.03% in autopsy series. The prognosis of cardiac sarcomas remains poor because it proliferates rapidly and distant metastases are often found at diagnosis. A 47-year-old male complained of persistent cough. The chest roentgenogram was normal. Subsequent computed tomography revealed a mass in the right atrium. Echocardiography and magnetic resonance imaging confirmed also a right atrial mass (34 x 35 mm) infiltrating the atrial septum. The tumor was completely resected en bloc, including the anterior and lateral right atrial walls, the left atrial dome, and a large segment of the superior vena cava, and reconstructed the atria and superior vena cava with bovine pericardium. The tumor was histologically and immunohistochemically diagnosed as undifferentiated pleomorphic sarcoma. This type of cardiac sarcoma is very rare and usually found in the left atrium. Twenty-seven months after surgery, the patient is doing well without metastasis or local tumor recurrence.
