Acquired aortic atresia: Catheter therapy using covered stents

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Medical Device Technology

Background:

• Aortic arch interruption typically requires surgical intervention to restore continuity.
• This study explores a novel percutaneous approach for aortic arch reconstruction.

Purpose of the Study:

• To evaluate the feasibility, safety, and effectiveness of percutaneous covered stent placement for functional aortic atresia.
• To report mid-term follow-up results of this innovative treatment strategy.

Main Methods:

• Nine patients with functional aortic interruption underwent percutaneous treatment.
• Procedures involved trans-catheter perforation, balloon dilation, and implantation of covered Cheatham-Platinum stents.
• Post-procedure angiograms and hemodynamic assessments were performed.

Main Results:

• Successful establishment of aortic arch continuity in all patients.
• Significant improvement in descending aortic systolic and diastolic blood pressure post-stenting.
• Minimal trans-stent gradients indicating good forward flow were observed.

Conclusions:

• Percutaneous treatment of functional aortic atresia using covered stents is a feasible and safe option.
• This technique provides an effective alternative to surgery with excellent short- and mid-term results.
