The double switch procedure is a surgical technique used to repair congenitally corrected transposition of the great arteries (L-TGA), which is a cardiovascular anomaly with atrioventricular and ventriculoarterial discordance.
The procedure consists of any of the following surgical combinations:
The double switch procedure is usually performed in L-TGA patients of several months to years of age. The aim is to minimize or prevent right ventricular or tricuspid valve dysfunction that complicates the anomaly. Prior to correction, patients may require training of the morphologic left ventricle using pulmonary artery banding.

There is more than one way to present the variety of congenital heart diseases. Whichever way they are categorized, 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.
