Summary
The Rashkind technique effectively closes patent ductus arteriosus (PDA) in adults and children, avoiding surgery. This percutaneous method shows high efficacy and safety, with most patients achieving complete closure.
Area of Science:
- Cardiology
- Interventional Cardiology
- Pediatric Cardiology
Background:
- Patent ductus arteriosus (PDA) is a common congenital heart defect.
- Surgical closure (thoracotomy) is the traditional treatment but carries risks.
- Percutaneous closure offers a less invasive alternative.
Purpose of the Study:
- To evaluate the efficacy and safety of the Rashkind technique for percutaneous PDA closure.
- To assess outcomes in a cohort of patients treated since 1989.
Main Methods:
- Retrospective analysis of 16 patients undergoing percutaneous PDA closure using the Rashkind umbrella device.
- Procedures performed via transvenous femoral or transarterial approach.
- Device size (12 mm or 17 mm) selected based on ductus diameter.
Main Results:
- Successful closure achieved in all patients, with 8 showing total occlusion and 8 partial closure initially.
- No mortality or morbidity reported.
- Complete closure confirmed by follow-up Doppler in 13 patients, eliminating the need for endocarditis prophylaxis.
Conclusions:
- The Rashkind technique is an effective and safe method for percutaneous PDA closure, avoiding thoracotomy in most cases.
- The procedure is well-tolerated across a wide age range.
- Further device miniaturization could enable application in neonates.
