title: Percutaneous closure of Ostium secundum atrial septal defect using amplatzer occlusion device.
abstract: OBJECTIVE
  To report our clinical experience with transcatheter closure of ostium secundum atrial septal defects (OS ASDs) using Amplatzer septal occluder.
  
  
  METHODS
  It's a retrospective study conducted between October 2005 and April 2010 and involving 34 patients. The procedures were conducted in the hemodynamic laboratory under general anesthesia with transthoracic (TTE) and transoesophageal echocardiographic (TEE) monitoring. Clinical and echocardiography assessments of the patients were conducted within 24 hours post procedure and several months after the procedure.
  
  
  RESULTS
  From the 34 patients, 28 (82%) were females. The middle age was 27.5 years. The mean ASD diameter was 19.4 mm by TTE; 18.1 mm [12-38] by TEE, and 23.4 by angiography. The average size of the implanted devices was 23.2 mm ranging from 10 to 34 mm.The final success rate of the procedure was 90.9% (30/33). One patient was excluded from transcatheter occlusion and three patients (8,6%) had complications including two prosthesis migrations and one large residual shunting. A total of 4 patients (11,7%) underwent surgery. No major complication (thromboembolic events, obstruction of intracardiac structures, cardiac perforation, device embolization and endocarditis) or death has occurred during follow-up and all devices were securely anchored without any persistent residual shunts.
  
  
  CONCLUSIONS
  Compared to previous data of the literature, percutaneous closure of OS ASDs using Amplatzer device appears safe and effective according to our experience of the cardiology department of Hedi Chaker Hospital.
