Novel technique to prevent prolapse of the Amplatzer septal occluder through large atrial septal defect

Abstract
We report on a new technique (holding the left atrial disk in the left atrium by a dilator) to prevent prolapse of the left atrial disk of the Amplatzer septal occluder during deployment in large atrial septal defects (ASDs). Two patients underwent successful closure of their ASDs using this new technique. Catheter Cardiovasc Interv 2003;60:543–545.
