Background: In this study, we aimed to assess the efficacy and outcome of transcatheter ductus arteriosus stenting in newborns and infants with ductal-dependent or decreased pulmonary circulation. Methods: Between July 2004 and January 2009, 45 patients with ductus-dependent or decreased pulmonary circulation underwent cardiac catheterization for stent implantation. Forty-seven stents in total were implanted in 42 (93.3%) of these 45 patients. The mean age at the time of the procedure was 66 days (3 days to 1.8 years) and mean weight was 4.4±2.1 kg (2-13.2). Premounted coronary stents of 3, 3.5, and 4 mm in diameter were used to cover the whole length of the ductus. Results: The stenting procedure was successfully completed in all 42 patients. There was no procedure related death. The mean ductal length was 13.2±3.8 mm (7.8-23 ) and the mean stent length was 13.9±3.8 mm (8-23). Mean arterial oxygen saturation before stent implantation was 66.0% ±8.1 (42-75) and increased to 85.7%±4.2 (75-95) after stenting. During a mean follow-up of 34.5±14.4 months (12-54), there was a significant reduction in pulse oxygen saturation six months after the procedure (78.8%±8.5; p
