Insights

Percutaneous interventions for coarctation of the aorta show promising long-term results, with varying success rates and complication profiles across different patient groups and treatment methods. Long-term survival is achievable, but reintervention rates highlight the need for ongoing management.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Pediatric Cardiology

Background:

  • Coarctation of the aorta is a congenital heart defect requiring intervention.
  • Percutaneous techniques offer treatment options, but long-term outcomes require further elucidation.
  • This review examines 21 years of experience with percutaneous treatment for coarctation of the aorta.

Purpose of the Study:

  • To review the long-term outcomes of percutaneous interventions for coarctation of the aorta.
  • To analyze results across four distinct treatment scenarios.
  • To evaluate survival rates, need for reintervention, and complication development.

Main Methods:

  • Retrospective review of 21 years of percutaneous interventions for coarctation of the aorta.
  • Categorization into four groups based on patient age and intervention type (balloon angioplasty vs. stenting).
  • Long-term follow-up including clinical assessment, hemodynamic, and angiographic studies.

Main Results:

  • Balloon angioplasty in infants had a high initial mortality (17%) but good long-term survival (83% at 19 years) with significant reintervention needs (43% surgery-free, 23% reintervention-free).
  • Balloon angioplasty in children/adults showed better long-term relief in discrete coarctation, with 6% late aneurysm formation.
  • Stent palliation in young children required further expansion and had risks of intrastent proliferation (18%) and aneurysm (18%).
  • Stent repair in older children/adults demonstrated significant and persistent relief, with low mortality (1.3%) and no late restenosis or aneurysms at 5-year follow-up.

Conclusions:

  • Percutaneous treatment for coarctation of the aorta yields variable long-term results depending on patient age and intervention strategy.
  • While initial outcomes can be excellent, particularly with stenting in older patients, long-term surveillance is crucial for managing potential complications like restenosis and aneurysm formation.
  • Stent palliation in young children necessitates careful management to accommodate growth and prevent complications, which are often treatable percutaneously.
