Primary cardiac angiosarcoma resection combined with right coronary artery bypass grafting.

A 41-year-old woman presented with symptoms of cardiac tamponade. Diagnosis of a primary malignant tumor in the right atrium without distant metastasis was made by echocardiography, computed tomography and coronary angiography. Aggressive surgery consisting of resection of the tumor including the right atrial wall together with the right coronary artery and sinus node was performed. This was followed by coronary artery bypass grafting with myocardial electrode implantation for reconstruction of the right atrial wall using an equine pericardium. Final diagnosis was of angiosarcoma by pathological examination. Consequently, the patient underwent additional radiotherapy and was discharged. She is currently in good health with no recurrence 1.5 years after surgery.
