Interventional therapy for coarctation of the aorta

Area of Science:

• Cardiology
• Pediatric Cardiology
• Interventional Cardiology

Background:

• The optimal interventional management for coarctation of the aorta (CoA) is currently debated.
• Surgical intervention timing for elective cases remains a point of contention.
• Various approaches to balloon angioplasty for CoA exist, differing in patient selection and timing.

Purpose of the Study:

• To review the current controversies and evidence regarding the interventional management of coarctation of the aorta.
• To compare the outcomes of balloon angioplasty versus surgical repair for native and recurrent CoA.
• To discuss the emerging role of balloon-expandable stents in complex CoA cases.

Main Methods:

• Review of recent reports and clinical data comparing balloon angioplasty and surgery for CoA.
• Analysis of outcomes for balloon dilation in native versus recurrent coarctation of the aorta.
• Evaluation of the use of balloon-expandable stents in complex and failed dilation cases.

Main Results:

• Recent reports suggest similar or slightly superior acute results for balloon dilation in native CoA compared to recurrent CoA.
• Balloon-expandable stents are increasingly utilized for complex CoA cases and after failed dilations.
• A significant proportion of patients undergoing balloon angioplasty may require reintervention.

Conclusions:

• The optimal interventional strategy for coarctation of the aorta requires further investigation.
• Balloon angioplasty is a viable option for native and recurrent CoA, with evolving techniques and stent use.
• A large multicenter study is necessary to definitively establish the roles of surgery and balloon dilation in CoA management.
