OP-086 New Modified Balloon-Assisted Technique to Provide Appropriate Deployment in the Closure of Large Secundum Atrial Septal Defect Using Amplatzer Septal Occluder




Objective


Transcatheter closure of secundum atrial septal defects (ASD) has been a well accepted, safe, alternative method to surgery. However the deployment of the device across the septum using the conventional method presents difficulties in large ASDs.




Material-Methods


In the modified balloon-assisted technique (modified BAT): a Tyshak balloon (Numed, Inc. USA) is placed in one of the left pulmonary veins and along sheath is placed in the right upper pulmonary vein. Through this sheath Amplatzer septal occluder deployed in a proper position with the help of Tyshak balloon, which prevents the left atrial disc to prolapse into the right atrium. Beginning from June 2011, the modified BAT has been used in the closure procedure of 30 (female/male: 18/12) patients with large ASD (group I). The outcomes of 58 (female/male: 40/18) age matched (under the age of 12) ASD patients with a minimum defect diameter of 15 mm, measured by transesophageal echocardiography, who underwent a conventional transcatheter ASD closure procedure were compared with the outcomes of group I.
