Arterial switch operation: myocardial ischemia reversed by internal mammary artery graft.
We report a case in which an internal mammary artery graft to the left anterior descending coronary artery was successfully used in a newborn boy to reverse life-threatening myocardial ischemia 24 hours after arterial switch operation. One year later, angiography showed patency of both the graft and the transposed coronary ostium with normal left ventricular function. A brief review of the literature shows encouraging results of internal mammary artery grafts in pediatric patients.
