ABSTRACT

In 1797, Scottish pathologist Matthew Baillie first described the morphologic details of transposition of the great arteries (TGA)1 in which the aorta arises entirely or largely from the right ventricle and the pulmonary trunk arises entirely or largely from the left ventricle (ventriculoarterial discordant connection). Surgical correction for this lesion was attempted during the 1950s either at the atrial or great artery levels.1 The first successful anatomic correction was performed in 1975,2 when Jatene and colleagues applied the arterial switch operation to infants with TGA and ventricular septal defect (VSD).
