A Serial Studies Of Transcatheter Closure Of Atrial Septal Defects

Part I Transcatheter Closure Secundum Atrial Septal Defect with Amplatzer Septal Occluder Device: a preliminary results of clinical applicationPurpose: To evaluate the efficiency and preliminary results of transcatheter closure of secundum atrial septal defect (ASD) using Amplatzer occluder device. Materials and methods: There was 34 patients. The mean age was 31.00±15.74 years (ranging from 5 to 53 years) and the mean weight was 50.69±16.62 Kg (ranging from 18 to 79 Kg). Transesophageal echocardiography (TEE) before the interventions confirmed the ASD with a diameter of 16.94±5.38 mm (ranging from 6 to 28 mm). Each ASD was occluded using Amplatzer occluder device through the percutaneous procedure. The closure procedure was guided by fluoroscopy and TEE. TEE were performed immediately to find whether there was residual shunt Transthoracic echocardiography (TTE), ECG and X-ray examination were done 24 hours, 1 month, 3- month and 1 year after the procedure to evaluate the efficiency. Results: The mean balloon stretched diameter of the ASDs was 21.82±5.31 mm (ranging from 8 to 32 mm). The mean diameter of the occluder selected was 23.62±5.52 mm (ranging from 23.62±5.52 mm (ranging from 10 to 34 mm). The successful rate of placement of the occluder was 100%. There was not any complication during the procedures, and emergency surgery was not needed. The trivial residual shunts were found in 10 cases (29.4%) immediately after the procedures, in 3 cases (8.8%) 24 hours after the procedures and in 2 cases (5.9%) 1 month after the procedures. All patients completed 3-month follow-up and there was no residual shunt found in any patient Six patients completed 1 year follow-up and no residual shunt and recanalization were found in all. Conclusion: Transcatheter closure of secundum ASD using...
