The mean weight at catheterization was 4.9\u2009\u00b1\u20091.0 kg and mean age was 5.7\u2009\u00b1\u20093.0 months. Successful device implantation was achieved in 374 (92%) patients without major complication and of these, complete occlusion was achieved in 356 (95%) patients at last available follow\u2010up. Device embolization occurred in 20 cases (5%). The incidence of device related obstruction to the left pulmonary artery or aorta and access related peripheral vascular injury were low. There were no deaths related to the procedure.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>Transcatheter closure of PDA can be accomplished in selected infants weighing <6 kg despite the manufacturer's recommended weight limit of 6 kg for most ductal occluders. The embolization rate is higher than previously reported in larger patients. Retrievability of the occluder and duct morphology needs careful consideration before deciding whether surgical ligation or transcatheter therapy is the better treatment option.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ccd.27212","type":"journal-article","created":{"date-parts":[[2017,8,11]],"date-time":"2017-08-11T11:22:50Z","timestamp":1502450570000},"page":"1135-1144","source":"Crossref","is-referenced-by-count":22,"title":["Outcome
