title: Anomalous origin of the left main coronary artery: anatomical correction and concomitant LIMA-to-LAD grafting.
abstract: A 55-year-old woman with angina pectoris and exertional dyspnea underwent surgical correction of an anomalous left main coronary artery (LMCA) originating from the right sinus of Valsalva. During the operation, the roof of the intramurally coursing LMCA was opened into the aortic lumen, and a neo-coronary ostium was created by suturing the circumference of the LMCA intima to the aortic intima. In addition, a left internal mammary artery (LIMA) to left anterior descending (LAD) coronary artery anastomosis was performed. Post-operative coronary angiography demonstrated two independent, patent orifices of both the LMCA and the right coronary artery. The technique presented herein, of combined anatomical correction and LIMA-to-LAD grafting, is feasible and leads to distinct angiographic and clinical improvement.
