Arterial switch operation: a new technique of coronary transfer

A successful outcome after arterial switch operation (ASO) for transposition of the great arteries (TGA) depends in large part on the adequacy of transfer of the coronary arteries to the neoaorta. The present paper describes a new technique of coronary transfer which was used in 43 patients: 28 neonates with TGA and intact septum (with coarctation in one), 10 neonates with TGA and ventricular septal defect (with coarctation in one), 2 children undergoing ASO after failed Senning operation and 3 patients with complex TGA. A standardized uniform technique of coronary transfer was used; this technique involved reimplantation of the two coronary ostia side by side after excision of a single button of neoaortic wall
