The purpose of this study was to evaluate the feasibility, clinical outcome, and resource utilization of transcatheter closure of large, symptomatic patent ductus arteriosus (PDA) in young infants, and compare the results with those of surgery. From January 2003 to December 2006, successful transcatheter implantation of the Amplatzer duct occluder was performed in 20 young infants (≤3 months of age) with large PDA who suffered from severe congestive heart failure despite medical treatment. The data was compared with a historical control of 18 young infants who underwent surgical ligation of PDA. Patient ages ranged from 18 to 89 days (mean 51.8) in the study group and 13 to 82 days (mean 39.9) in the control group. Patient weight ranged from 2.7 to 7.1kg (mean 4.24) in study group and 2.5 to 5.7kg (mean 3.79) in the control group. Between the 2 groups, there was no significant difference in the rate of complications. Patients who underwent transcatheter closure utilized significantly fewer resources (length of hospital stay and total cost) than those who underwent surgery. In conclusion, percutaneous device occlusion with Amplatzer duct occluder in small, symptomatic infants is feasible and more cost-effective compared with surgery. In experienced hands with careful preprocedural evaluation and delicate manipulation, the safety of transcatheter closure with Amplatzer ductus occluder in this age group can be assured and major complication avoided. Revision of the delivery sheath, making it kink-resistant, and PDA shape-tailored devices should further optimize the procedure.
