The Mustard procedure was developed in 1963 by Dr. William Mustard at the Hospital for Sick Children.It is similar to the previous atrial baffle used with a Senning procedure, the primary difference being that the Mustard uses a graft made of Dacron or pericardium, while the Senning uses native heart tissue.
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.
Arterial switch procedure Immediate post-operative (Jatene procedure) d-TGA + VSD neonate. The Jatene procedure surgery is the preferred, and most frequently used, method of correcting d-TGA. [2] [6] It is ideally performed on an infant between 8–14 days old.
The Senning procedure is an atrial switch heart operation performed to treat transposition of the great arteries. It is named after its inventor, the Swedish cardiac surgeon Åke Senning (1915–2000), also known for implanting the first permanent cardiac pacemaker in 1958.
Two variants of the atrial switch operation developed – the Senning procedure (1950s) which uses the patient's own tissue (pericardium) to construct the baffle, and the Mustard procedure (1960s), which uses a synthetic material. [4] It has largely been replaced by the arterial switch operation. [4]
William Thornton Mustard OC MBE (August 8, 1914 – December 11, 1987) was a Canadian physician and cardiac surgeon.In 1949, he was one of the first to perform open-heart surgery using a mechanical heart pump and biological lung on a dog at the Banting Institute.

In this scenario, a second procedure with an atrial switch is done after recovery from the first intervention. The atrial switch is done via either the Mustard procedure, in which the atrial septum is cut out and a baffle is made with the pericardial baffle, or a Senning procedure, in which the atrial septum itself is used to create the baffle.
