Double switch procedure

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:

• atrial inversion surgery (either the Senning or the Mustard repair) and Jatene arterial switch
• atrial inversion surgery (either the Senning or the Mustard repair) and Rastelli-type repair (also known as the Ilbawi or Senelli procedure)

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.
