Atrial Septal Defect

WHAT YOU SHOULD KNOW:

An atrial septal defect (ASD) is a hole in the septum (wall) between the upper chambers of your heart. This hole may be small or large. An ASD is a common heart defect that people are born with. It prevents blood from flowing through your heart in a normal way. Your heart works harder to pump blood. Over time, an ASD can damage your heart and lungs.

CARE AGREEMENT:

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

RISKS:

Closure of the ASD may increase your risk for a heart infection called bacterial endocarditis. With or without treatment, you may have an irregular heartbeat. Without treatment, you may have frequent lung infections and increased blood pressure in your lungs. You may also develop heart failure. You may develop blood clots that cause a stroke, which can be life-threatening.

WHILE YOU ARE HERE:

Informed consent

is a legal document that explains the tests, treatments, or procedures that you 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 medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.

Medicines:

  • Blood thinners prevent blood clots. They may make you bruise or bleed more easily.

  • Heart medicine helps your heart beat more regularly.

Monitoring:

  • An EKG records the electrical activity of your heart. It is used to check the amount of time it takes for the right ventricle to contract (pump blood). An EKG can show signs of other problems that may happen with ASD.

  • A pulse oximeter is a device that measures the amount of oxygen in your blood.

Tests:

  • Blood gases (ABGs) are used to test the amount of oxygen and carbon dioxide in your blood. The results can tell caregivers how well your lungs are working.

  • A cardiac catheterization is a test used to show how well your heart is working, or to measure pressure. A tube is threaded into your heart through a blood vessel in your leg or arm. You may be given a dye before x-ray pictures of your arteries are taken to help caregivers see the pictures better. Tell the caregiver if you have ever had an allergic reaction to contrast dye.

  • A chest x-ray can show if the right atrium and ventricle are larger than the left atrium and ventricle. The pictures can also show if the pulmonary arteries are larger than they should be.

  • An echocardiogram uses sound waves to show pictures of your heart. It can show caregivers the size of the ASD and how blood flows through your heart. It can also show how well your heart is pumping.

Treatment:

  • Cardiac catheterization is a procedure that is used to place a patch or plug on the hole through a catheter (thin tube). The catheter is placed into an artery in your groin and guided up to your heart.

  • Open heart surgery may be needed to close the ASD with stitches, a patch, or a piece of your heart tissue.
