Description
Summary:To describe our initial experience with the Occlutech Duct Occluder (ODO) for percutaneous closure of patent ductus arteriosus (PDA). Retrospective review of patients undergoing transcatheter PDA closure with the ODO in 2 academic centers. From April 2013 to September 2017, 42 patients underwent PDA closure. Median age at implantation was 34 months (range 4 months–68 years) and median weight was 12 kg (range 4.1–57 kg). Ducts were Krichenko type A duct (n = 34), type E (n = 6), and type C (n = 2). The mean duct diameter was 3.76 mm (range 1.69 to 9.95 mm, median 3.1 mm). Implantation succeeded in all. There was neither device embolization nor hemolysis. At device release, immediate angiogram showed a small residual shunt in 54.7%. During follow-up, Doppler echocardiography demonstrated 71% of full occlusion at day one, rising to 95% at one month and 100% at one year and half after implantation. The mean maximal systolic pressure gradient in left pulmonary artery was 4.2 ± 4.3 mm and across the distal aortic arch 5.4 ± 4.7 mm Hg. No patient had any significant stenosis with clinical relevance. ODO is safe and effective in transcatheter closure of PDA including relatively large sized ducts. The results are satisfactory with a high level of full occlusion and a low rate of complications. Further evaluation with larger studies and longer follow-up will be required to confirm these preliminary good results. •Transcatheter closure of patent ductus arteriosus is an alternative to surgery.•The Occlutech duct occluder in a new device.•The Occlutech duct occluder is safe and effective in the occlusion of arterial duct.
