Fontan fenestration closure with Amplatzer Duct Occluder II device
1Department of Paediatric Cardiology, Our Lady's Children's Hospital, Crumlin, Dublin, Ireland.
Summary
Fontan fenestration closure using the Amplatzer Duct Occluder II (ADO2) device is a safe and effective procedure. This method significantly improves oxygen saturation without complications, making it a cost-effective option.
Area of Science:
- Cardiovascular Interventions
- Pediatric Cardiology
- Congenital Heart Disease Management
Background:
- Fontan fenestration closure is a standard catheter intervention.
- Existing occlusion devices are often bulky.
- The Amplatzer Duct Occluder II (ADO2) is a low-profile, flexible, and cost-effective alternative.
Purpose of the Study:
- To evaluate the efficacy and safety of the Amplatzer Duct Occluder II (ADO2) for Fontan fenestration closure.
- To assess the impact of ADO2 device closure on patient oxygen saturation and pulmonary artery pressure.
Main Methods:
- Retrospective review of patients undergoing Fontan fenestration closure with the ADO2 device.
- Analysis of procedural success rates.
- Comparison of pre- and post-procedural oxygen saturation and mean pulmonary artery pressure.
- Assessment of complications.
Main Results:
- Thirteen patients were included in the study.
- All procedures were technically successful with no complications.
- Significant increase in oxygen saturation (Mean=+12%, P<0.01) post-closure.
- No significant change in mean pulmonary artery pressure (Mean=+0.5 mm Hg, P=0.08).
Conclusions:
- Fontan fenestration closure with the ADO2 device is a simple, rapid, and cost-effective procedure.
- The ADO2 device is suitable for occluding Fontan fenestrations of various sizes and morphologies.
- This approach offers a favorable safety and efficacy profile.
