An echocardiogram (echo), also known as a cardiac ultrasound, uses sound waves to evaluate the anatomy and function of your child’s heart. It is one of the most commonly used tests in children for evaluation of heart disease.
What is an echocardiogram?
An echocardiogram is a safe and painless test that allows your doctor to evaluate the anatomy and function of your child’s heart. Electrodes (small plastic stickers placed on the body) are used to check the heart’s rhythm while ultrasound technology produces an image of the heart to help your doctor determine how the blood is flowing. An echocardiogram is performed on children of all ages and sizes, including newborns and fetuses. Your doctor can use the images from an echocardiogram to identity potential heart disease.
There are several types of echocardiograms:
- Transthoracic Echocardiogram: This is the standard type of echocardiogram that is performed with a handheld device, known as a transducer, which is placed on the patient’s chest while lying down. The transducer (a form of ultrasound technology) transmits high frequency sound waves that bounce off the heart structures and produce images and sounds that are used by your doctor to detect potential heart damage and disease.
- Stress Echocardiogram: This type of echocardiogram is used to determine how well the heart and blood vessels are working, specifically the coronary arteries, during a period of stress, which is induced by medication or exercise. Imaging is taken via a transducer before and after the medication has been administered or the exercise has been completed.
- Transesophageal Echocardiogram (TEE): This type of echocardiogram is used to obtain more detailed images of certain parts of the heart by using a long, thin, tube, known as an endoscope, to guide the transducer inside the body and down the esophagus (which is located directly behind the heart) while your child is sedated.
Why is an echocardiogram performed?
Your doctor may suggest an echocardiogram to check if heart problems may be the cause of symptoms, such as shortness of breath and chest pain.
An echocardiogram can help your doctor identify:
- Any structural or functional problems with the heart valves, such as narrowing or leaking
- Blood clots in the heart
- Holes in the heart
- Problems with the blood vessels that are responsible for bringing blood to and from the heart
- Problems with the heart's lining
- The size and shape of the heart and its walls
- The strength of the heart's pumping ability
What can I expect during an echocardiogram?
Before the echocardiogram is performed, a technician will attach electrodes (small plastic stickers) to your child’s chest. Then, the technician will place a cool gel on your child’s chest and use a transducer to glide the gel across your child’s chest. Your child will feel slight pressure as the technician moves the transducer around your child’s chest to capture images of the heart. Once the echocardiogram is complete, the technician will wipe the gel from your child’s chest and remove the electrodes. To obtain clear images, it is important for child to be as still as possible during the exam. Depending on the information your doctor needs, your child may need more than one of the types of echocardiograms listed above. Each type of echocardiogram involves few, if any, risks.
