[Transluminal angioplasty for aortic coarctation in newborns and infants]
Insights
Transluminal balloon angioplasty effectively reduced aortic coarctation gradients in infants. However, long-term success varied, with younger infants requiring more surgical interventions for aortic coarctation.
Area of Science:
- Cardiology
- Pediatric cardiology
- Interventional cardiology
Context:
- Aortic coarctation is a critical congenital heart defect.
- Transluminal balloon angioplasty is a potential treatment for aortic coarctation.
- Infants under one year represent a challenging demographic for this intervention.
Purpose:
- To evaluate the efficacy and outcomes of transluminal balloon angioplasty in infants with aortic coarctation.
- To compare results between two groups of infants based on age and initial gradient.
Summary:
- Fourteen infants with aortic coarctation underwent balloon angioplasty, divided into two groups.
- Significant reduction in transcoarctation gradient was observed in both groups immediately post-procedure.
- Outcomes varied, with older infants (over 3 months) showing better results than neonates, though many still required surgery.
Impact:
- Balloon angioplasty can provide immediate hemodynamic improvement in pediatric aortic coarctation.
- Age and initial gradient are critical factors influencing the long-term success of angioplasty in infants.
- Further research is needed to optimize outcomes and reduce surgical reintervention rates in this population.
Abstract:
It has been done transluminal angioplastic with catheter balloon in 14 patients who are under 1 year of age and who are affected by aortic coarctation. For this study, they were divided in two groups. The first one was formed by newborn children whose transcoarctation gradient was 52 mm Hg in average. The second group was integrated by 9 newborn children whose transcoarctation gradient was 59 mm Hg. After this experience was done the gradient descended to 9 and 15 mm Hg respectively. Twenty four hours later, two months later and over two more months, there were follow-up of the clinical situation, the evolution of the pulse, differential arterial pressure and the need of surgery. Of the first group only one of the patients, who is now 2 years old, is in good clinical condition; the others needed to be surgically intervened. Of the second group 4 patients, all of whom were over 3 months old at the time of the angioplastic had positive results. The rest needed surgical intervention.
