Pouch Transfer for Single Coronary Artery with Nodal Artery Variant in Arterial Switch Operation

The arterial switch operation with single coronary artery variance is an independent risk factor for increased operative mortality. There are reports of technical modifications, such as the double-barreled sinus pouch configuration, to improve geometric reimplantation of the single coronary into the neoaortic sinus. We describe the novel application of this technique for transferring a single coronary artery with a separate nodal artery emanating from the opposite sinus during an arterial switch operation.
