The arterial switch operation offers excellent long-term outcomes for transposition of the great arteries. However, operative mortality for this complex procedure remains a significant concern requiring further attention.

Area of Science:

  • Pediatric Cardiac Surgery
  • Congenital Heart Defects
  • Surgical Outcomes

Background:

  • Arterial level repair is the preferred method for transposition of the great arteries.
  • This study reviews a decade of experience with the arterial switch operation (ASO).

Purpose of the Study:

  • To evaluate the outcomes of the arterial switch operation in patients with transposition of the great arteries and related conditions.
  • To identify risk factors influencing operative mortality and long-term results.

Main Methods:

  • A retrospective review of 299 patients undergoing ASO between 1991 and 2001.
  • Patients were categorized into two groups based on the complexity of their congenital heart defect.
  • Data collected included demographics, operative details, mortality, and follow-up outcomes.

Main Results:

  • Overall operative mortality was 19%, with higher rates in patients with ventricular septal defects (33%) compared to those without (8.8%).
  • Major causes of mortality included pulmonary hypertensive crisis, sepsis, and left ventricular failure.
  • Follow-up showed 91% of survivors were asymptomatic and off medication, with a low reoperation rate.

Conclusions:

  • The arterial switch operation yields excellent long-term results for survivors.
  • Operative mortality, particularly in complex cases, remains a critical area for improvement.
