Outcome and Immediate Complications of Device Occlusion of Different Types of Patent Ductus Arteriosus with Range of Devices

Objective: The aim of our study was to report the outcome and immediate complications of PDA device closure, comparing ducts according to Krichenko classification. Study Design: Quasi experimental study. Place and Duration of Study: Pediatric Cardiology Department of Armed Forces Institute of Cardiology / National institute of Heart Diseases (AFIC/NIHD) from 1st May 2012 to 30th Nov 2013. Patients and Methods: Total 368 consecutive cases, were included with intention of transcatheter closure of patent ductus arteriosus (PDA). Detailed echocardiography was done before procedure. Aortogram determined duct size, length, narrowest diameter and morphology. Device attempted only after duct was considered suitable. Results: The mean narrowest duct diameter was 4.5±2.4 mm. Out of 368 cases, five cases were considered unsuitable for device closure after aortogram. In two cases, device embolized after deployment and in one case procedure abandoned due to technical reasons. There was no cardiac perforation, tamponade or death in our study population. The success according to Krichenko duct types was 100% for type A, 100% for type B, 87.5% for type C, 100% for type D and 100% for type E. Conclusion: PDA device closure is a safe and effective therapeutic option in vast majority of cases. Type C tubular type ducts are more difficult to negotiate with high complication rates.
