Percutaneous transcatheter PDA device closure in infancy

ABSTRACT

To evaluate the results and complications associated with transcatheter closure of patent ductus arteriosus [PDA] in infants. Quasi-experimental study. Paediatric Cardiology Department of Armed Forces Institute of Cardiology / National Institute of Heart Diseases [AFIC/NIHD], Rawalpindi, from December 2010 to June 2012. Infants undergoing transcatheter device closure of PDA were included. All patients were evaluated by experienced Paediatric Cardiologists with 2-D echocardiography and Doppler before the procedure. Success of closure and complications were recorded. The age of patients varied from 05 - 12 months and 31 [56.4%] were females. Out of the 55 infants, 3 [5.4%] were not offered device closure after aortogram [two large tubular type ducts and one tiny duct, considered unsuitable for device closure]; while in 50 [96.1%] patients out of remaining 52, the duct was successfully closed with transcatheter PDA device or coil. In one infant, device deployment resulted in acquired coarctation, necessitating device retrieval by Snare followed by surgical duct interruption and another patient had non-fatal cardiac arrest during device deployment leading to abandonment of procedure and subsequent successful surgical interruption. Local vascular complications occurred in 12 [21.8%] of cases and all were satisfactorily treated. Transcatheter device closure of PDA in infants was an effective procedure in the majority of cases; however, there were considerable number of local access site vascular complications
