ABSTRACT
AIM:
To describe our initial experience with the Occlutech Duct Occluder (ODO) for percutaneous closure of patent ductus arteriosus (PDA).METHODS:
Retrospective review of patients undergoing transcatheter PDA closure with the ODO in 2 academic centers.RESULTS:
From April 2013 to September 2017, 42 patients underwent PDA closure. Median age at implantation was 34â¯months (range 4â¯months-68â¯years) and median weight was 12â¯kg (range 4.1-57â¯kg). Ducts were Krichenko type A duct (nâ¯=â¯34), type E (nâ¯=â¯6), and type C (nâ¯=â¯2). The mean duct diameter was 3.76â¯mm (range 1.69 to 9.95â¯mm, median 3.1â¯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⯱â¯4.3â¯mm and across the distal aortic arch 5.4⯱â¯4.7â¯mmâ¯Hg. No patient had any significant stenosis with clinical relevance.CONCLUSIONS:
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.Palavras-chave
