Atrial Septal Defect Transcatheter Closure In Children


Atrial septal defect (ASD) transcatheter closure is also called ASD closure. ASD closure is done to close a hole in your child's heart.


The week before your child's procedure:

  • Write down the correct date, time, and location of your child's procedure.
  • When you take your child to see his caregiver, bring a list of his medicines or the medicine bottles. Tell caregivers if your child uses herbs, food supplements, or over-the-counter medicine. If your child is allergic to any medicine, tell his caregiver.
  • Ask your child's caregiver if your child needs to stop using certain medicines before his procedure.
  • A dye will be used during your child's procedure to help the pictures of his heart show up better. Tell the caregiver if your child has ever had an allergic reaction to contrast dye.
  • Your child may need an echocardiogram, EKG, or chest x-ray before his procedure. Ask your child's caregiver for information about these and other tests your child may need. Write down the date, time, and location of each test.

The night before your child's procedure:

Ask caregivers about directions for eating and drinking.

The day of your child's procedure:

  • You or a close family member will be asked to sign a legal document called a consent form. It gives caregivers permission to do the procedure or surgery on your child. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.
  • Ask your child's caregivers before you give him his medicines today. These medicines include insulin, diabetic pills, or heart pills. Bring a list of your child's medicines or the pill bottles with you to the hospital.
  • Caregivers may put an IV tube into your child's vein. A vein in the arm is usually chosen. Your child may be given liquids and medicine through the IV.
  • An anesthesiologist will talk to you and your child before the surgery. Your child may need medicine to keep him asleep or numb an area of his body during surgery. Tell caregivers if anyone in your family has had a problem with anesthesia in the past.


What will happen:

Your child will get more anesthesia medicine to make him go to sleep. He will also get medicine called local anesthesia to numb the area where the catheter will go in. Catheters will be put into blood vessels in your child's groin, neck, or arm. The catheters are gently threaded (pushed) into the blood vessels and heart. Caregivers will close your child's ASD with a device. Once the device is put over the ASD, the pressure between the right and left upper chambers of the heart will help hold it in place. Heart tissue will grow over the device in about 3 months.

After your child's procedure:

The catheter will be removed and a tight pressure bandage will be put on your child's wound. Your child may have stitches. Caregivers will put pressure on the area to stop the bleeding. A pressure bag may be used to apply pressure. Your child will need to lie still and flat for about 4 hours after the procedure to prevent bleeding. Do not let your child get out of bed until caregivers say it is okay. When caregivers see that he is okay, he will be taken to his room.


  • Your child cannot make it to his procedure.
  • Your child has a fever.
  • Your child has a cold or the flu.
  • You have questions or concerns about your child's procedure.

Seek Care Immediately if

  • The problems for which your child is having the procedure get worse.


  • The catheter may cause bleeding, a bruise, and soreness in the area where the catheter was placed. Your child could bleed more than expected and need open heart surgery to repair the hole. Air bubbles in your child's blood could cause a stroke. Blood clots may form and go to your child's lungs or brain and cause a stroke. Your child may also get a blood clot in his leg or arm. These problems may become life-threatening.
  • Your child could get a collapsed lung or an infection. He could have an allergic reaction or kidney problems from the dye used during the procedure. A blood clot may form on the ASD closure device. The ASD closure device could move out of place and your child may need open heart surgery to repair the hole. Without this procedure, your child's health condition could get worse. He may develop heart failure.
