Safety and efficacy of transcatheter device closure of patent ductus arteriosus in pediatric patients: Long-term outcomes

Aims: Patent ductus arteriosus (PDA) is among the most prevalent congenital heart diseases in current times. The aim of this study is to evaluate contemporarily the safety and efficacy of transcatheter device closure of PDA at long-term follow-up. Materials and Methods: Transcatheter closure of PDA was attempted in 205 children between 2008 and 2015 using the Amplatzer duct occlude (ADO). Ductal anatomy was accurately delineated on lateral and right anterior oblique view on aortic angiogram. All children underwent complete clinical evaluation, electrocardiography, chest X-rays, and echocardiography prior to discharge and at 1-month, 6-month, and annual follow-up thereafter. Results: Of a total of 205 cases, 64% were females; the mean age was 7.92 ± 3.61 years (1–17 years), while the mean weight was 16.68 ± 10.82 (5–41 kg). ADOs-I were used in all the cases. The procedure was successful in 99.03% of patients with excellent results. Two patients required surgical closure due to device-induced aortic obstruction and left pulmonary stenosis. There were no cases of procedural deaths, device embolization, device infection, and infective endocarditis. All children fared well at a median follow-up of 94 months with no complications. Conclusion: The long-term data showed that percutaneous transcatheter closure of PDA using ADO was safe and effective in pediatric population with minimal complications.
