Interventional treatment of PDAs still remains a challenge in those children with low body weight and a large PDA. The Nit\u2010Occlud PDA\u2010R\u00ae device was developed and especially designed for large PDAs. We report our most recent experience in children with a body weight lower than 10 kg.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>The PDA\u2010R\u00ae device was used in seven children (age 1\u201310, median 6 months) with a body weight from 4.1 to 9.7 kg (median 5.9 kg): ductal length was 12 mm (median), with a large ampulla (median 9 mm) which exceeded the diameter of the aorta (median 6 mm) and large diameter (median minimal diameter 4 mm). In six cases, the Nit\u2010Occlud PDA\u2010R was selected with an aortic disc of 12 mm and in one case an occluder with an aortic disc of 14 mm.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Occlusion of the PDA was documented by angiography and\/or echocardiography in all cases.
