Percutaneous reintervention on aortic coarctation stenting.

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Interventional Cardiology

Background:

• Aortic coarctation stenting in early childhood can necessitate reintervention due to somatic growth.
• Long-term outcomes of reintervention for pediatric aortic coarctation stenting require further evaluation.

Purpose of the Study:

• To evaluate the efficacy and safety of percutaneous reintervention in patients who underwent aortic coarctation stenting at a young age.
• To assess the outcomes of balloon re-expansion versus re-stenting in pediatric aortic coarctation.

Main Methods:

• Retrospective analysis of 177 patients with aortic coarctation treated with stent implantation (1993-2018).
• Focus on 33 patients treated before age 12 requiring reintervention.
• Reintervention involved balloon angioplasty or re-stenting.

Main Results:

• Successful reintervention in 91% of patients (30/33).
• Significant reduction in aortic gradient (22±10 to 6±6 mmHg) and increase in lumen diameter (9±6 to 15±3 mm).
• Minor complications included femoral artery occlusion (8) and bleeding requiring covered stents (2).

Conclusions:

• Percutaneous reintervention is a safe and effective strategy for managing aortic coarctation stented in childhood.
• Patients treated with aortic coarctation stents at an early age can be successfully re-treated after somatic growth completion.
