Corrective Surgery

Arterial switch operations (ASO) are now-days preferred over Atrial switch procedures (Mustard and Senning Operations) because of the following reasons-

• Arterial switch procedure are comparatively easier to perform
• ASO have similar survival benefits compared to atrial switch procedure
• Decreased risk of complications like arrhythmias and heart failure in ASO compared to atrial switch procedures
• Decreased peri-operative mortality in ASO compared to atrial switch procedures

Salient features of surgery are

• It is best to perform the ASO as early as possible in the children. Most infants undergo definitive repair within the first 2 weeks of life.
• The type of surgical procedure done depends on the type of lesion the child has i.e. simple or complex transposition of the great arteries.
• The general rules that are followed are-
  • Simple D-TGA (D-TGA without any associated lesion)- Arterial switch operation (ASO).
  • D-TGA plus ventricular septal defect-Arterial switch operation (ASO) and VSD closure.
  • D-TGA plus large VSD plus pulmonary stenosis - Rastelli procedure
