The arterial switch operation (ASO) is a successful surgery for transposition of the great arteries (TGA) and Taussig-Bing anomaly (TBA). Recent outcomes show high survival and low reoperation rates, demonstrating ASO safety and effectiveness.

Area of Science:

  • Pediatric Cardiac Surgery
  • Congenital Heart Disease
  • Surgical Outcomes

Background:

  • The arterial switch operation (ASO) is a cornerstone in treating cyanotic congenital heart disease.
  • This study evaluates recent outcomes of ASO in infants with transposition of the great arteries (TGA) and Taussig-Bing anomaly (TBA).

Purpose of the Study:

  • To assess the safety and efficacy of the arterial switch operation (ASO) in neonates and infants.
  • To evaluate intermediate-term outcomes, including survival and reoperation rates, for TGA and TBA patients.

Main Methods:

  • A retrospective review of 125 consecutive arterial switch operations (ASOs) performed between 1995 and 2003.
  • Patients with TGA (with intact septum or VSD) and TBA were included, regardless of size or associated defects.

Main Results:

  • The 30-day mortality was 1.6%, with an overall 7-year actuarial survival rate of 96.3%.
  • Complex coronary artery anomalies were noted but did not increase operative risk. Freedom from reoperation was 90% at 7 years.
  • All survivors were in New York Heart Association (NYHA) functional class I with normal saturation, and no late coronary events occurred.

Conclusions:

  • The arterial switch operation (ASO) is a safe and effective procedure for TGA and TBA with favorable intermediate-term outcomes.
  • Current surgical techniques achieve near 100% operative survival rates and a low need for reoperation.
