Insights
Nonsurgical treatment for aortic coarctation and recoarctation, including balloon dilatation and stent implantation, shows high short-term and long-term effectiveness with minimal complications. Stenting is promising for older children.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Pediatric Cardiology
Context:
- Aortic coarctation is a congenital heart defect requiring effective treatment.
- Nonsurgical interventions are increasingly utilized for aortic coarctation and recoarctation.
- Evaluating outcomes of minimally invasive techniques is crucial for patient management.
Purpose:
- To analyze the efficacy and safety of nonsurgical treatments for aortic coarctation and recoarctation.
- To compare the results of balloon dilatation and stent implantation.
- To assess complications and long-term outcomes of these interventions.
Summary:
- Balloon dilatation and stent implantation were performed in 51 and 6 children, respectively, for recoarctation, with a small number for native coarctation.
- Both techniques significantly reduced the pressure gradient across the coarctation, with effective dilatation achieved in most cases.
- Complications were minimal, with a few requiring re-intervention; stent implantation showed excellent results in older children.
Impact:
- Nonsurgical treatment for aortic coarctation and recoarctation is highly effective in the short and long term.
- Minimally invasive techniques offer a safe alternative with few complications.
- Stent implantation presents a promising option for managing recoarctation in older pediatric patients.
Objectives:
To analyze the results of nonsurgical treatment of aortic coarctation and recoarctation by evaluating the results of each technique, and its complications and outcome.
Patients And Methods:
The results were as follows: 51 children underwent balloon dilatation due to recoarctation (86.5 %); two underwent dilation of a native coarctation (3.3 %) and six underwent stent implantation for recoarctation (10 %). Age ranged from 2 to 236 months (109 +/- 63.45 months) with a follow-up of between 1 and 156 months (38.87 +/-32.96 months).
Results:
The mean predilatation gradient in children with recoarctation was 34 +/- 11.62 mmHg, which decreased to 11 +/- 5.38 mm Hg (p < 0.0001). In 12 patients (20.3 %) effective dilatation was not achieved. The size of the stenosis was 6.7 +/- 2.35 mm predilatation, which increased to 9.3 +/- 3.10 mm (p < 0.0001) after dilatation with a percentage increase of 50.97. There were very few complications. Six children required subsequent redilatation. The experience with stent showed a mean gradient of 32.83 +/- 10.62 mm Hg, which decreased to 7.3 +/- 3.8 mm Hg (p < 0.0001) with a balloon/stenosis ratio of 1.94.
Conclusions:
We conclude that the interventionist technique is highly effective in both native coarctation and recoarctation in the short term, as well as subsequently, with very few complications. The stent technique produces equally good results in older children, which is promising for the future.
