Abstract

Primary heart tumours are rarely encountered. Myxomas, which are included in this group of tumours, are the most common primary benign neoplasms of the heart and approximately 75-80% of them are found in the left atrium. In our case, a 72-year-old female patient, who had complaints of shortness of breath, pain in the chest and swelling in the legs that increased in the last three months. We present a case with a myxoma in the right atrium with a dimension of 80x60x15 mm attached to the interatrial septum. According to the echocardiographic examination, it clinically shows signs of right heart failure, almost completely obstructs the right atrium and extends to the right ventricle. Ascending aortic aneurysm was also detected on the echocardiography. Despite the fact that the right atrial mass obliterating the cardiac chambers was removed by surgery, the valve pathology caused by the lesion did not regress.
