Double Switch Surgery
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)
For L-TGA patients aged from few months to years, the double switch procedure is normally performed. The objective is to mitigate or prevent dysfunction of the right ventricular or tricuspid valve which complicates the anomaly. Patients may need morphologic left ventricle preparation using pulmonary artery banding before correction.
