[Surgical treatment of left atrial myxoma with coronary arterial lesion].

We experienced two patients of left atrial myxoma with coronary arterial lesion. One patient, who was a 52-year-old female, was transferred to our institute with the diagnosis of acute myocardial infarction. The coronary angiogram showed an abrupt 99% stenosis of posterolateral branch of circumflex artery with no atherosclerotic lesion, and the echocardiography revealed a left atrial myxoma disturbing the blood flow across the mitral valve. She was in congestive heart failure with pulmonary hypertension, and underwent an emergency removal of the myxoma under cardiopulmonary bypass. Another patient, who was a 70-year-old male, was admitted to our institute with the chief complaint of chest pain. The coronary angiogram showed an 75% atherosclerotic stenosis of the right coronary artery, and the echocardiography revealed the left atrial myxoma. He received a removal of myxoma and a coronary artery bypass grafting simultaneously. These 2 patients went a good postoperative course and live a lively life with no local recurrence. In this paper, the surgical treatment of left atrial myxoma with coronary arterial lesion was reviewed.
