Arterial switch operation (ASO) or arterial switch, is an open heart surgical procedure used to correct dextro-transposition of the great arteries (d-TGA).[1][2]

Its development was pioneered by Canadian cardiac surgeon William Mustard and it was named for Brazilian cardiac surgeon Adib Jatene, who was the first to use it successfully. It was the first method of d-TGA repair to be attempted, but the last to be put into regular use because of technological limitations at the time of its conception.

Use of the arterial switch is historically preceded by two atrial switch methods: the Senning and Mustard procedures.[3]

The atrial switch, which was an attempt to correct the physiology of transposition, had significant shortcomings that the arterial switch improved upon, in particular a reduced kinking of the coronary arteries when combined with the LeCompte maneuver. The end result is that the aorta is repositioned behind the pulmonary arteries, functionally lengthening it and causing less angulation at the coronary origins.[4]
