Summary
Percutaneous closure of atrial septal defects and patent foramen ovale is a safe and effective treatment for children. This minimally invasive procedure offers a viable alternative to surgical intervention for selected pediatric patients.
Area of Science:
- Pediatric Cardiology
- Interventional Cardiology
- Congenital Heart Disease
Background:
- Atrial septal defects (ASDs) and patent foramen ovale (PFO) are common congenital heart conditions.
- Percutaneous closure techniques have emerged as alternatives to surgical repair.
Purpose of the Study:
- To evaluate the efficacy and safety of percutaneous closure for ASDs and PFOs in children.
- To report initial and follow-up experiences with device closure in a pediatric cohort.
Main Methods:
- A 2-year study involving percutaneous closure of seven ASDs and one PFO in pediatric patients.
- Utilized Amplatzer and Cardioseal devices for defect closure.
- Employed a compliant sizing balloon to determine appropriate device diameter.
Main Results:
- Successful percutaneous closure was achieved in all patients.
- No acute complications were observed during the procedures.
- Follow-up revealed transient complications in two patients (headaches, atrial flutter/leak), both of which resolved.
Conclusions:
- Percutaneous closure of ASDs and PFOs is an effective and safe therapeutic option for selected children.
- This approach provides a valuable alternative to surgical treatment in pediatric populations.
