Extension of coronary artery with double flap technique in a complicated arterial switch operation.

The increased distance between the coronary ostium and the reimplantation site poses technical challenges in older patients with transposition of the great arteries (TGA) and complex coronary artery anomalies. In this report, we describe a technique for coronary artery reimplantation using a pedicle flap on the pulmonary artery (PA) to create a tunnel resulting in an extension of the coronary button.
