Rerouting anomalous coronary artery origin in aortopulmonary window in newborn.

Coronary artery anomalies may accompany the aortopulmonary window and, if not noticed, may cause catastrophic consequences. The repair of the aortopulmonary window is quite straightforward; however, establishing a normal coronary pattern may challenge the repair. When the anomalous origin of the coronary artery is on the defect rim, right at the location where sutures are to be placed, it may interfere with proper suture placement. A technique to overcome such a technical obstacle and reroute the anomalous right coronary in such cases is described.
