The Norwood procedure shows promise for hypoplastic left heart syndrome, with reduced circulatory arrest time and improved early outcomes. Further experience may enhance long-term survival rates.

Area of Science:

  • Pediatric Cardiac Surgery
  • Congenital Heart Disease Management

Background:

  • The Norwood procedure is a critical intervention for hypoplastic left heart syndrome (HLHS).
  • Recent advancements aim to improve outcomes for infants with HLHS.

Purpose of the Study:

  • To evaluate the early and late outcomes of the Norwood procedure in infants with HLHS.
  • To assess the impact of a modified aortic arch repair and CO2 administration on patient stability.

Main Methods:

  • A cohort of 19 infants with HLHS underwent the first-stage Norwood procedure.
  • Modified aortic arch repair was employed to reduce circulatory arrest time.
  • CO2 was added to the inspired gas mixture to mitigate postoperative instability.

Main Results:

  • Early mortality rate was 31.5% (6 out of 19 infants).
  • Modified aortic arch repair significantly reduced circulatory arrest time.
  • CO2 administration led to less early postoperative instability.
  • Five late deaths occurred, two due to cavopulmonary operation failure.
  • Eight survivors are in good condition, with most awaiting further surgical stages.

Conclusions:

  • The Norwood procedure is a viable option for HLHS, with encouraging early results.
  • Continued experience and refined perioperative care are expected to improve long-term outcomes.
  • Careful patient selection for subsequent cavopulmonary operations is crucial for success.
