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. ⋯ 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.

CABG with all arterial grafts using both the internal thoracic artery (RITA, LITA), the right gastroepiploic artery (GEA) and the inferior epigastric artery (IEA) was performed in 26 patients from July 1989 to August 1991. There were no early and late deaths. Early postoperative coronary angiography in all patients revealed that the best choice of anastomosis was RITA to LAD, LITA to LCX or DIA, and GEA to RCA (type A). All arterial grafts CABG is safe and feasible, but the saphenus vein graft must be used to avoid the anastomosis from small GEA to small LCX.
