Atrial septal defect repair in children – transcatheter procedure – Definition
An atrial septal defect is a hole in the wall between the two upper chambers (right and left atriums) of the heart. A transcatheter procedure is a minimally-invasive way to repair the hole. During this procedure, a device is implanted to seal the hole. As your child recovers, the device will trigger the heart tissue to grow. The tissue will slowly grow over the hole.
