The main limitation in most centers is the difficult vertical tubular or convoluted ducts that represent real challenges to interventional pediatric cardiologists. We present our experience in patent ductus arteriosus (PDA) stenting with some technical tips to overcome difficulties, especially in stenting tortuous or long tubular ducts. This study was conducted on all patients with cyanotic congenital heart disease who underwent PDA stenting between January 2011 and December 2018.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>We attempted to stent the PDA in 43 patients, with a success rate of 93% (40 patients) and only one procedural mortality. There was also one stent migration that needed to be treated with urgent surgery. Three-fourths of the patients had difficult ductal morphology and origin. One stent was used to cover the PDA in 27 patients (62.8%), two stents were used in 13 (30.2%), and three stents were used in 2 patients (4.6%). In-stent stenosis rate was 12.5% (5 patients) and the development of progressive left pulmonary artery stenosis was seen in two patients (5%). Pulmonary artery growth was adequate in all patients.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>PDA stenting is an effective method of palliation for patients with duct-dependent pulmonary circulation. It has low morbidity and mortality rates.
