Area of Science:

  • Pediatric Cardiology
  • Congenital Heart Disease
  • Aortic Valve Disease

Context:

  • Congenital valvular aortic stenosis (AS) presents complex management challenges in children.
  • Recent advancements offer improved survival rates for neonates with critical AS.

Purpose:

  • To discuss current management strategies and controversies in pediatric congenital valvular aortic stenosis.
  • To compare the efficacy and indications of surgical open valvotomy versus balloon valvuloplasty.
  • To evaluate newer techniques like annulus enlargement and the Ross procedure.

Summary:

  • Improved survival reported for neonates with critical AS via surgical open valvotomy and balloon valvuloplasty, though direct comparison is pending.
  • Extended aortic valvuloplasty shows promise for recurrent AS/insufficiency, but requires longer follow-up.

  • Annulus enlargement technique (since 1991) allows larger valve insertion without significant risks.
  • The Ross procedure demonstrates favorable early outcomes (mortality <5%, survival 80-90% at 4-8 years).

    • Impact:

    • Provides an overview of current and evolving treatment options for pediatric aortic stenosis.
    • Highlights the need for extended follow-up to assess long-term efficacy and potential complications of various procedures.
    • Informs clinical decision-making regarding the optimal management of congenital valvular aortic stenosis in children.
