Senning repair

Last revised by Azza Elgendy on 23 Feb 2020

The Senning repair is one of two "atrial switch" procedures used to functionally correct transposition of the great arteries (the other being the Mustard repair). 

The two repairs share a similar fundamental principle. Systemic blood flow is redirected away from the right ventricle and toward the left ventricle. As the main pulmonary artery comes off the left ventricle in transposition, essentially "two wrongs make a right."

One of the main adverse effects of the Senning repair is arrhythmia. During creation of the septal baffle and redirection of the atrial flow, the sinoatrial node may be injured. The Senning repair has a lower rate of arrhythmia than the Mustard repair, but the arterial switch procedure is now preferred to correct transposition, partly to avoid this complication.
