Catheter interventions, including balloon angioplasty and stenting, are effective treatments for coarctation of the aorta. These minimally invasive options offer good success rates and safety profiles for adult patients.

Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology

Background:

  • Coarctation of the aorta traditionally treated with surgery.
  • Catheter interventions have emerged as a viable alternative over the past two decades.

Purpose of the Study:

  • To evaluate the efficacy and safety of catheter interventions for coarctation of the aorta.
  • To compare balloon angioplasty and primary stent implantation.
  • To determine optimal initial therapy for adult patients.

Main Methods:

  • Review of balloon angioplasty and primary stent implantation for coarctation of the aorta.
  • Analysis of outcomes including gradient reduction, restenosis, and aneurysm formation.
  • Comparison of results for native and recurrent coarctation.

Main Results:

  • Balloon angioplasty achieves satisfactory gradient reduction in ~80% of patients; restenosis and aneurysm rates <10%.
  • Primary stent implantation shows low rates of suboptimal gradient reduction (<5%), restenosis (<5%), and complications (<5%).
  • Outcomes for native and recurrent coarctation are similar with catheter interventions.

Conclusions:

  • Catheter interventions are established, safe, and effective for coarctation of the aorta.
  • Both balloon angioplasty and stenting demonstrate good success rates.
  • Catheter intervention should be considered the initial therapy for most adult patients.
