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.{{cite journal |last1=Prokšelj |first1=Katja |last2=Brida |first2=Margarita |title=Atrial switch operation for transposition of the great arteries: tricuspid regurgitation matters |journal=Heart |date=18 July 2022 |doi=10.1136/heartjnl-2022-321398 |pmid=35851320 |s2cid=250642197 |url=https://heart.bmj.com/content/early/2022/07/18/heartjnl-2022-321398 |language=en |issn=1355-6037|url-access=subscription }} It has largely been replaced by the arterial switch operation.
