A 73-year-old woman with dyspnea was diagnosed with a left atrial myxoma by echocardiography. Right and left circumflex coronary angiography showed neovascularity in the tumor and the blood flow jet extending from the tumor to the left atrial cavity, which led to the steal phenomenon in the left anterior descending artery. Surgical excision of the left atrial tumor and the maze procedure were performed with a cardiopulmonary circuit. To our knowledge, this is the 1st study to report the development of the coronary artery steal syndrome due to a cardiac myxoma. Exercise testing would involve risks such as embolism and left ventricular inflow disturbance; furthermore, the presence of concomitant chest symptoms with cardiac myxoma is not rare. Therefore, preoperative coronary angiography would be used for differential diagnosis and for detecting the coronary artery disease, which is reported to be common in patient with cardiac myxomas.
