    Abstract:
    OBJECTIVE: To evaluate the results of transcatheter closure for patent ductus arteriosus (PDA) by different devices in children. METHODS: Seventy-eight cases of PDA in children (7 months to 14 years old), diagnosed by physical examination and transthoracic 2-dimensional echocardiography (TTE), were included in the study. The examination included the cardiac catheterization, photograph of the thoracic aorta and conventional technique of PDA closure. Among these patients, 16 were treated with coils, 9 with Amplatzer duct occluder (ADO), and 53 with native produced PDA occluders. RESULTS: TTE examination on the next day of the operation showed that PDAs were completely occluded in 76 cases, while the other 2 cases treated by coil had minimal residual shunt. Sixty-four patients, who were detected enlargement of the left ventricle before the operation, showed obvious diminishment of the cardiac size. By the end of 3 months, TTE examination showed that the closure of PDA was complete, and the left ventricle size was normal in 77 cases, while one case treated with coil had minimal residual shunt, which persisted for more than 4 years. The 3 - 80 months follow-up showed that the closure of PDA was complete in 77 cases, the configurations of the left ventricle, the thoracic aorta,and the left pulmonary artery were all normal. The occluders were well remained in situ. CONCLUSION: The usual procedures of transcatheter closure for PDA are effective and safe with ADO, native produced occluders and coil in children. Interventional method, which shows minute insult, few complications, and few adverse effects, can substitute the thoracic surgery.
