Abstract
Using an Amplatzer duct occluder, 106 patients (weight 21 +/- 18 kg) underwent an attempt at catheter closure of a persistently patent ductus arteriosus (PDA). Their age ranged from 22 days to 48 years. The PDA measured between 1.2 to 8.1 mm at its narrowest diameter. The device was successfully implanted in 105 patients. The immediate closure rate was 70% and gradually increased to 100% at 1-month follow-up. There was no clinical evidence of hemolysis and no incidence of device embolization or bacterial arteritis. Doppler evaluation showed no evidence of aortic arch or pulmonary artery obstruction. The device, which is currently undergoing multicenter clinical trial in the United States, is proving to be a safe and effective device for closure of the persistently PDA.Keywords
