Arterial switch operation or arterial switch, is an open heart surgical procedure used to correct dextro-transposition of the great arteries ; 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.
The atrial switch, which was an attempt to correct the physiology of transposition, had significant shortcomings. The arterial switch sought to address them. This has emerged as an anatomically as well as physiologically appropriate solution.
