Balloon angioplasty of adult aortic coarctation
Insights
Balloon angioplasty effectively treats adult aortic coarctation, reducing gradients and blood pressure. This minimally invasive procedure offers a promising, economical alternative to surgery, though long-term data is needed.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Vascular Surgery
Background:
- Aortic coarctation is a congenital heart defect affecting the aorta.
- Native adult aortic coarctation often requires intervention to manage hypertension and prevent complications.
- Conventional surgical repair carries risks and can be resource-intensive.
Purpose of the Study:
- To evaluate the efficacy and safety of balloon angioplasty for treating native adult aortic coarctation.
- To assess hemodynamic and clinical outcomes following percutaneous transluminal balloon angioplasty.
Main Methods:
- Retrospective analysis of 13 adult patients with native aortic coarctation undergoing balloon angioplasty.
- Pre-procedure hemodynamic and angiographic assessment.
- Percutaneous transluminal balloon angioplasty using appropriately sized balloon catheters.
Main Results:
- Successful gradient reduction and upper limb blood pressure decrease in all treated patients.
- Only four patients required ongoing antihypertensive medication post-procedure.
- Two cases of false aneurysms occurred, necessitating surgical intervention; no deaths were reported.
Conclusions:
- Balloon angioplasty is a safe and effective treatment for native adult aortic coarctation.
- The procedure demonstrates favorable outcomes compared to surgery and offers economic advantages.
- Further long-term follow-up is recommended to establish balloon angioplasty as a first-line therapy.
Objective:
To examine the use of balloon angioplasty in the treatment of native adult aortic coarctation.
Design:
Haemodynamic and angiographic studies to establish the diagnosis of aortic coarctation were established before carrying out the procedure in all patients.
Setting:
All the studies and angiographic procedures were performed in a large district general hospital within the departments of cardiology and radiology. There was careful perioperative monitoring. The mean hospital stay was three days.
Patients:
15 adult patients (with clinical, haemodynamic, and angiographic evidence of native aortic coarctation) were considered for this treatment. 13 were offered balloon angioplasty. One was excluded, as there was no significant gradient across the lesion. One patient had complete atresia at the site of the coarctation.
Interventions:
Percutaneous transluminal balloon angioplasty was carried out with balloon catheters diameter 2 mm less than the diameter of the aorta immediately below the left subclavian artery to minimise the possibility of tearing the aortic wall.
Main Outcome Measures:
Abolition or significant reduction of the preoperative gradient was achieved in all 13 patients treated. Reduction in blood pressure of the upper limb was also achieved in all of the patients. Only four patients required continued antihypertensive treatment. Two patients developed false aneurysms after the procedure and required surgery. No deaths occurred. These results compare favourably with conventional surgery and are much more economical.
Conclusions:
Balloon angioplasty could become the first line treatment for all patients with native adult aortic coarctation, but longer term follow up is required to validate this.
