Introduction/Objective. Transcatheter closure is a well-established procedure for treatment of patent ductus arteriosus (PDA). We aimed to make a comparison between transcatheter PDA occlusion with Flipper coil and Amplatzer Duct Occluder (ADO) and to determine the incidence and significance of procedural complications. Methods. Between November 2004 and October 2014, 148 patients were eligible for transcatheter PDA closure at the University Children’s Hospital in Belgrade, Serbia. The median age was 5.9 years (the range of 0.9 years to 17.3 years) and the median weight was 21 kg (the range of 8.8 kg to 94 kg). Follow-up evaluations with Doppler echocardiogram were performed at one day, three months, and one and two years after the PDA occlusion. Results. Median narrowest PDA diameter was 1.5 mm (the range of 0.5 mm to 5.6 mm). Flipper coil was used for PDA closure in 84 (59.2%) and ADO in 58 patients (40.8%). There was no significant difference in the rate of immediate complete closure between the coil and the ADO group (86.9% vs. 75.9%, p = 0.089), but a significantly higher rate of complete closure was achieved with ADO at one day (83.3% vs. 98.3%, p = 0.004), three months (85.7% vs. 100%, p = 0.002), and both one and two years after the implantation (91.7% vs. 100%, p = 0.041). In total, 12 complications occurred during the procedure, seven of which with coil and five with ADO occlusion of PDA. Conclusion. Transcatheter closure of PDA using both coils and ADOs is a very safe and effective procedure. ADO proved superior to coil in terms of complete closure rate as early as one day after the procedure.
