Atrial septal defect closure using the Gore HELEX® Septal Occluder

Also known as: ASD surgery, ASD repair, ASD closure.

What is atrial septal defect closure using the Gore HELEX® Septal Occluder?

An atrial septal defect (ASD) is a hole in the wall between the two upper chambers of the heart. It allows blood to flow from the left side of the heart to the right side improperly. The Gore HELEX® Septal Occluder is a device that’s implanted into the heart to close the opening.

What happens during the procedure? 

The child is placed under general anesthesia. Then a catheter, or tube, is inserted into a blood vessel to the hole. A balloon is inserted through the catheter to measure the hole. Then the Gore HELEX® Septal Occluder is inserted into the hole to repair the defect.

Is any special preparation needed? 

The child may need to stop taking some medications and refrain from food or drink for a certain amount of time before the procedure.

What are the risk factors? 

The risks of atrial septal defect closure using the Gore HELEX® Septal Occluder include broken blood vessels, fluid around the heart or the risk of the Gore HELEX® Septal Occluder moving or falling out of place.
