Abstract
Left main coronary artery atresia is an extremely rare coronary anomaly in which there is no left coronary ostium and the left main trunk ends blindly. Ectopic origin of the left coronary artery from the left ventricle is an even rarer condition. Herein, we describe the case of a 37-year-old woman whose left main coronary artery atresia was not corrected during previous surgical correction of patent ductus arteriosus and aortic insufficiency. Five years after that first operation, the patient developed severe angina and heart failure. She underwent coronary artery bypass grafting with greater saphenous vein directly to the left main coronary artery trunk, along with associated procedures. The operative findings revealed an ectopic and atretic ostium of the left main coronary artery from the interleaflet triangle between the left and noncoronary cusps, which we believe is a specific congenital coronary anomaly.
