Surgical vs. percutaneous atrial septal defect closure: Remote effects on left ventricular diastolic function

UK multicenter experience using the gore septal occluder (GSOTM) for atrial septal defect closure in children and adults

“…Additionally, such devices cause significant artifact during magnetic resonance imaging (MR) of the thorax, although the device itself can be usefully interrogated by MR . Finally, the potential for a long‐term local and systemic chronic foreign body reaction exists as is the possibility of such devices interfering with septal dynamics which may create functional problems in later years . Despite these potential concerns, the ASO device provides a safe, effective platform for atrial defects (ASD) closure in experienced hands.…”
