Non-surgical closure of patent ductus arteriosus with the Rashkind PDA occluder system
Insights
Transcatheter closure of Patent Ductus Arteriosus (PDA) using the Rashkind occluder system is safe and effective in children. This non-surgical method successfully closed PDA in all 18 pediatric patients studied.
Area of Science:
- Pediatric Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Patent Ductus Arteriosus (PDA) is a common congenital heart defect requiring intervention.
- Transcatheter closure offers a less invasive alternative to surgical repair.
- The USCI Rashkind PDA occluder system is a device used for this procedure.
Purpose of the Study:
- To evaluate the safety and efficacy of the USCI Rashkind PDA occluder system for transcatheter PDA closure in children.
- To assess the procedural success and early outcomes of this non-surgical technique.
Main Methods:
- Eighteen pediatric patients with PDA underwent transcatheter closure using the USCI Rashkind PDA occluder system.
- Patients' ages ranged from 1.2 to 14 years, with weights from 8 to 36 kg.
- Device implantation involved 12 mm and 17 mm occluders, with outcomes assessed by aortogram and Doppler color flow mapping.
Main Results:
- Successful PDA occlusion was achieved in all 18 children.
- Post-procedure imaging showed complete closure in 6 patients and trivial/small residual flow in 12.
- Doppler mapping within 3 days confirmed complete closure in 9, with residual flow in 9 others.
Conclusions:
- The transcatheter technique utilizing the Rashkind PDA occluder system is a safe and effective method for non-surgical PDA occlusion in pediatric patients.
- This approach provides a viable alternative to surgical intervention for PDA closure.
Abstract:
Transcatheter closure of Patent Ductus Arteriosus (PDA) was done in 18 children using the USCI Rashkind PDA occluder system. Patient age ranged from 1.2 to 14 years and their weights ranged from 8 to 36 kg. Isolated restrictive PDA was present in 15 patients; 3 had additional cardiac defects. The diameter of the PDA ranged from 2 to 6 mm as determined by lateral aortogram. PDA occlusion was successfully done in all 18 children. Ten 12 mm and eight 17 mm occluders were implanted with no complications. Post-implant aortogram showed complete ductal closure in 6 and trivial or small residual ductal flow in 12 cases. Doppler color flow mapping done within 3 days of the procedure showed complete ductal closure in 9, 8 had trivial ductal flow and 1 had small ductal flow. Transcatheter technique using a Rashkind PDA occluder system is a safe and effective method of non-surgical PDA occlusion.
