Clinical application of transcatheter closure in the treatment of secundum atrial septal defects using Amplatzer occluder device

Objective To evaluate the treatment efficiency of transcatheter closure of secundum atrial septal defect (ASD) using Amplatzer occluder device. Methods There were 11 patients with ASD.The patient's age was ranging from 5 to 52 years. All patients with ASD were occluded using Amplatzer occluder device under guidance of fluoroscopy and transesophageal echocardiography(TEE) through percutaneous approach. Transesopha-geal echocardiograms were performed immediately and transthoracic echocardiography (TTE) was done at 24h, 1 month and 3 month after the procedure to evaluate the efficiency. Results The treatment efficiency of all patients was very well. No residual shunt was found in these patients after the procedures. Conclusion Transcathe-ter closure of secundum ASD using Amplatzer occluder device is an safe and efficient nonsurgical method.
