Abstract Objective: To evaluate the clinical efficancy of transcatheter closure of atrial septal defect(ASD) with occlusion device in pediatric patients. Methods: 215 patients with ASD, 93 males, 122 females, at a mean age of 10.2 years(ranged from 2 to 15 years) and with a mean weight of 35.8kg(ranged from 11 to 87kg) were studied. Nine cases were complicated with pulmonary stenosis, one was complicated in each of the following defects superiorventricular tachycardia; ventricular tachycardia; ventricular septal defect; patent ductus arteriosus; Ⅲ° AVB, mitral valve prolapse and mitral regurgitaion. The diameter of ASD was measured by TTE and/or TEE, ascertaining the location and size of ASD. Occlusive device was sized to be equal to or 1～2mm more than the diameter of balloon streched. Results: All patients had successful implantation of the device. The success rate was 100%. The diameter measured by TTE was 5～32mm(mean 17.14mm). The diameter measured by TEE was 7～32mm(mean 18.45mm). Neither complication nor residual shunt was found in any of the patients. Conclusion: Occlusive device is safe and efficient in pediatric patients with ASD guided by echo sonography.
