Objective: The aim of this study was to present our experiences on transcatheter patent ductus arteriosus (PDA) closure with different devices, mostly the Amplatzer Piccolo Occluder, in infants weighing between 2-10 kg. Material and Methods: In this study, the files of 31 patients who underwent transcatheter PDA closure between December 2019 and August 2022 were reviewed retrospectively. Results: Transcatheter PDA closure was performed on 31(14 female) infants weighing between 2-10 kg. The mean age of patients was 10.7±6.7 months (2-28), and the mean weight was 6.6±2 kg (3-9.9). The median narrowest diameter of the ductus was 2.2 mm (IQR 2-3) and the median ductus length was 6 mm (IQR 4.75-8). The procedural success rate of all interventional procedures was 88% (30 of 34). Complications occurred in a total of four patients including failure of device implantation in one patient, post-procedural device embolization in 2 patients, and the significant residual shunt in one patient. None of the patients required surgery. In 34 interventional procedures, 3 of which were reintervention, 34 devices were used. Twenty-seven (79%) of them were Amplatzer Piccolo Occluder. The median fluoroscopy and procedural times were 10.5 minutes (IQR 7.25-18.5) and 40 minutes (IQR 35-57.5) respectively. The mean duration of follow-up was 10.3±8.8 months (1-32 months). Conclusion: In our experience, transcatheter treatment of PDA with the Amplatzer Piccolo Occluder device which was our first choice for appropriate duct anatomy and size in infants weighing between 2-10 kg, is safe and effective.
