Abstract:
Objective To assess the immediate efficacy of transcatheter closure of patent ductus arteriosus(PDA) using the angled duct occluder(ADO). Methods 9 patients(1 male, 8 female) underwent transcatheter closure of PDA using the ADO. The mean PDA diameter at its narrowest segment was (5.8?1.9) mm, ranging 3 to 10 mm. A 6-9F long sheath was used for the delivery of ADO. Results The devices were deployed successfully in all patients. Angiographies showed no shunt across the device 15 min after the implatation of ADO. Within 1 week, echocardiography revealed complete closure in all patients. There were no complications. Conclusions The transcatheter closure of PDA using ADO is an effective and safe procedure. The device matches with the shape of aortic cavity much more precisely than Amplatzer duct occluder.
