Objectives: The Cardia septal occluder (Intrasept, CSO) is a new transcatheter ASD occlusion device. We sought to analyze safety, efficacy, and follow-up results of percutaneous closure of ASD using this new device.
Methods: Between April 2007 and December 2007, we attempted transcatheter closure of ASD with CSO device under the guidance of transthoracic (8) or transesophageal echocardiography (2) at our institution. Indications of ASD closure are significant left to right shunt and suitable defect rims showed by detailed transthoracic echocardiographic examination.
Results: Device implantation was successful in all ten patients (%100). The median age was 7.5 (4.5-24) years and median weight was 30 (16-64 kg) kg. The median Qp/Qs ratio was 1.7 (range, 1.5 to 2.4), and the median ASD size as assessed by transthoracic echocardiography was 15.3 mm (range, 9.7 to 15 mm). The median device size used was 20 mm (14 to 24 mm). Total occlusion rate was 60% (6/10) immediately after completion of the procedure, rising to 90 % (9/10) the day after. Displacement of aortic side wing from right side to left causing residual shunt was the only complication encountered. Small residual shunt persisted in this patient but no intervention was needed during follow up.
Conclusions: Transcatheter closure of ASD with this new device is an effective and safe procedure in medium sized ASD’s. Our results should be confirmed in larger number of patients.
