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.


Before your child's procedure:

  • Informed consent is a legal document that explains the tests, treatments, or procedures that your child may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your child's medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done to your child. Make sure all of your questions are answered.
  • An IV is a small tube placed in your child's vein. Caregivers use the IV to give your child medicine or liquids.
  • Blood tests may be done to check your child's condition before the procedure. Your child may need to have blood drawn more than once.
  • Blood thinners may be given to prevent blood clots during the procedure.
  • Anesthesia makes your child comfortable during the procedure. Caregivers will work with you to decide which anesthesia is best for your child.
    • General anesthesia keeps your child asleep and free from pain during the procedure. They may give your child anesthesia through his IV. Your child may breathe it in through a mask or a tube placed down his throat. The tube may cause your child to have a sore throat when he wakes up.
    • Local anesthesia is a shot of medicine put into the skin around the area where the catheter will be put in. It is used to numb the area and dull the pain. Your child may still feel pressure or pushing during the procedure.

During your child's procedure:

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.

  • Tell your caregiver if your child has any of the following:
    • Chest pain or discomfort
    • Change in color or temperature of his arm or leg
    • Pain, numbness, or tingling in his arm or leg
    • Pain in his back, thigh, or groin
    • Nausea
    • Excessive sweating
  • Antinausea medicine may be given to calm your child's stomach and control vomiting. Your child may have an upset stomach after the procedure.
  • Your child will be able to eat and drink gradually after his procedure. He will begin with ice chips or clear liquids such as water, broth, juice, and clear soft drinks. If his stomach does not become upset, he may then eat soft foods, such as ice cream and applesauce. Once he can eat soft foods easily, he may slowly begin to eat solid foods.


  • 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.


You have the right to help plan your child's care. Learn about your child's health condition and how it may be treated. Discuss treatment options with your child's caregivers to decide what care you want for your child.
