Atrial Septal Defect Transcatheter Closure


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



  • Antibiotics help prevent a heart infection called bacterial endocarditis. You may need to take antibiotics before dental or other procedures for up to 6 months after your ASD closure. Ask your primary healthcare provider (PHP) or cardiologist how long after the ASD closure you must wait before you can go to the dentist. Tell caregivers about your ASD closure. Always take your antibiotics as directed.
  • Aspirin may be given to help prevent blood clots.
  • Blood thinners may be given to help prevent blood clots. Clots can cause strokes or heart attacks, and can be life-threatening. Blood thinners make it more likely for you to bleed or bruise. Follow these and other safety precautions you receive:
    • Watch for bleeding from your gums or nose. Watch for blood in your urine and bowel movements. Use a soft washcloth on your skin and a soft toothbrush on your teeth to keep your skin and gums from bleeding. If you shave, use an electric shaver. Do not play contact sports, such as football.
    • Many medicines cannot be used with blood thinners. Tell your dentist and other caregivers that you take blood-thinning medicine. Wear or carry medical alert information that says you are taking this medicine.
    • Tell your PHP right away if you forget to take the medicine, or if you take too much. You will need to have a blood test called the INR regularly. The INR shows how long it takes your blood to clot. Your PHP will use the INR results to decide how much medicine is right for you.
    • Talk to your PHP about the foods you eat. This medicine works best when you eat about the same amount of vitamin K every day. Vitamin K is found mainly in green leafy vegetables. Ask your dietitian or PHP for a list of foods that are high in vitamin K.

  • Take your medicine as directed. Call your PHP if you think your medicine is not helping or if you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your PHP or cardiologist as directed:

Write down your questions so you remember to ask them during your visits.


  • Keep your leg or arm straight as much as possible. For the next few days, do not bend over. Do not sit for longer than 1 hour without getting up.
  • You may feel like resting more after your procedure. Slowly start to do more each day. Rest when you feel it is needed.
  • Do not lift heavy objects. Ask when you can return to your daily activities, such as bathing.

Wound care:

Carefully wash the wound with soap and water. Dry the area and put on new, clean bandages as directed. Change your bandages when they get wet or dirty.

Do not smoke:

If you smoke, it is never too late to quit. Smoking increases your risk for heart disease and stroke. Ask your cardiologist for information if you need help quitting.

Contact your cardiologist if:

  • You have a fever or chills.
  • Your heart feels like it is beating too fast or unevenly.
  • You have questions or concerns about your condition or care.

Seek care immediately or call 911 if:

  • You have any of the following signs of a stroke:
    • Part of your face droops or is numb
    • Weakness in an arm or leg
    • Confusion or difficulty speaking
    • Dizziness, a severe headache, or vision loss
  • You feel lightheaded, short of breath, and have chest pain.
  • You cough up blood.
  • Your arm or leg feels warm, tender, and painful. It may look swollen and red.
  • You start to bleed from your catheter site.
  • Your incision is swollen, red, or has pus or foul-smelling fluid coming from it.
  • The bruise where the catheter was placed gets bigger.
  • The limb where the catheter was placed is numb, painful, or changes color.
