Percutaneous balloon aortoplasty for restenosis after extended aortic arch anastomosis for type B interrupted aortic
1Department of Pediatrics, Yamagata University School of Medicine, Japan.
Insights
Percutaneous balloon aortoplasty effectively treated restenosis in a 4-month-old infant with interrupted aortic arch. The procedure safely reduced pressure gradients and increased aortic arch diameter without complications.
Area of Science:
- Pediatric Cardiology
- Interventional Cardiology
- Congenital Heart Disease
Background:
- Postoperative aortic obstruction is a known complication after aortic arch surgery.
- Type B interrupted aortic arch (IAA) requires complex surgical repair, often involving aortic arch anastomosis.
- Restenosis can occur after surgical repair, leading to significant hemodynamic compromise.
Abstract:
A 4-month-old boy underwent a percutaneous balloon aortoplasty for restenosis after extended aortic arch anastomosis for type B interrupted aortic arch (IAA). Balloon aortoplasty resulted in a decrease in the peak systolic pressure gradient across the obstructive segment from 84 mmHg to 19 mmHg and in an increase in diameter from 2.5 mm to 4.3 mm. No complications related to the procedure were observed. We assume that balloon aortoplasty can be effective and safe for relieving postoperative aortic obstruction associated with IAA.
