Percutaneous closure of patent ductus arteriosus with the Nit-Occlud® patent ductus arteriosus device in 268 consecutive cases

Background: The pfm Nit-Occlud® patent ductus arteriosus (PDA) device is well established for interventional closure of PDA. However, there are still limited data concerning its efficacy and follow-up in larger patient groups. Aims: This study aimed to evaluate the safety and efficacy of the Nit-Occlud® PDA device, implanted both through transpulmonary and transaortic approach, in a large cohort. Methods: From July 2008 to December 2015, 268 consecutive patients were admitted for transcatheter closure of a PDA and were treated with the Nit-Occlud® coil. Clinical, echocardiographic, and angiographic data were evaluated. Results: The median age was 5.2 years (range, 5 months to 62 years), and the median weight was 19.3 kg (range: 5.5-97 kg). Ten (3.7%) patients had weight
