Relative Risk Factors for Cardiac Erosion Following Transcatheter Closure of Atrial Septal Defects

Abstract

In addition to aortic rim deficiency, which was almost universal among erosion cases, there were several relative risk factors for erosion after ASD closure with the Amplatzer septal occluder device. To understand the mechanisms of and absolute risk factors for this uncommon but serious complication, an adequately powered prospective study with thorough echocardiographic evaluation will be critical.
