[Experiences with the Rashkind duct occluder]

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Devices

Background:

• Persistent ductus arteriosus (PDA) is a congenital heart defect.
• Transvenous occlusion offers a less invasive alternative to surgical repair.

Purpose of the Study:

• To evaluate the efficacy and safety of transvenous occlusion for PDA in adult patients.
• To assess the use of the Rashkind umbrella occluder in PDA closure.

Main Methods:

• Five adult patients with PDA underwent transvenous occlusion using a Rashkind umbrella.
• Patient demographics, ductus diameter, pulmonary artery pressure, and procedural outcomes were recorded.
• Calcification of the ductus wall was noted in four patients.

Main Results:

• Successful occlusion without residual shunt was achieved in four out of five patients.
• One patient experienced occluder embolization requiring retrieval and re-intervention.
• This patient had a residual shunt after the second attempt at occlusion.

Conclusions:

• Transvenous closure with a Rashkind umbrella is a viable treatment for PDA in adults.
• The procedure is generally safe and effective, though complications like embolization can occur.
• Careful patient selection and device management are crucial for optimal outcomes.
