Growth of the atrial septum after amplatzer device closure of atrial septal defects in young children

Abstract

ASDs in young children are not central in the septum, but proximate to the aorta. After ASO, the device remains in close proximity to the aorta. With somatic growth, the septum grows asymmetrically, and device position relative to the aorta is constant. Our study was not powered to detect rare serious adverse events such as erosion, but aortic rims were consistently zero and yet no events occurred.

Interventional Closure of Secundum Type Atrial Septal Defects in Infants Less Than 10 Kilograms: Indications and Procedural Outcome

“…All residual shunts spontaneously closed after a median follow up of 2.1 years, demonstrating the principal success of this procedure in this specific group of patients. Gossett et al analyzed growth of the atrial septum after device closure of ASDs in young children, giving a further insight into endothelial growth around the implanted devices with the endogenous potential to close small residual shunts after device implantation …”

Late Bacterial Endocarditis after Amplatzer Atrial Septal Occluder Without Residual Shunt in a Pediatric Patient

“…Atrial septal defects are the second most common congenital heart malformations, following ventricular septal defects, with an incidence rate of 5% to 10% [1].…”
