Senning repair

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.

Congenital heart disease

There is more than one way to present the variety of congenital heart diseases. Whichever way they are categorised, it is helpful to have a working understanding of normal and fetal circulation, as well as an understanding of the segmental approach to imaging in congenital heart disease.
