Background Interventional closure of patent ductus arteriosus (PDA) has become a common and safe procedure in most pediatric cath labs. Interventional treatment of PDAs still remains a challenge in those children with low body weight and a large PDA. The Nit‐Occlud PDA‐R® 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. Materials and Methods The PDA‐R® device was used in seven children (age 1–10, 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‐Occlud PDA‐R was selected with an aortic disc of 12 mm and in one case an occluder with an aortic disc of 14 mm. Results Occlusion of the PDA was documented by angiography and/or echocardiography in all cases. At a mean follow‐up of 21.4 months, no flow obstruction to the left or right pulmonary artery or new onset coarctation of the aorta was noted. Conclusions The Nit‐Occlud PDA‐R® device is suitable in children with a body weight below 10 kg when a relative large PDA is present. © 2015 Wiley Periodicals, Inc.
