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.

If a child is born with a hole between the upper chambers of the heart, the blood can flow backward into the right side of the heart and into the lungs. This triggers the heart to work harder. Over time, this can lead to damage to blood vessels in the lungs and congestive heart failure. The procedure is done to fix the hole.
