Transthoracic Echocardiogram

A transthoracic echocardiogram (echo) is a standard, non-invasive imaging technique that allows your doctor to see how your heart is beating and pumping blood.

An echocardiogram uses sound waves to produce images of your heart. An echo technologist spreads gel on your chest and then presses a device known as a transducer firmly against your skin, aiming an ultrasound beam through your chest to your heart. The transducer records the sound wave echoes that your heart produces. A computer converts the echoes into moving images on a monitor. If your lungs or ribs obscure the view, a small amount of intravenous dye may be used to improve the images.

Why is an Echo performed?

An echo gives important information about how the heart looks and functions. This is often key to how heart problems are treated and followed. It is one of the commonest heart tests performed.

Your echo results can reveal:

  • How your heart muscle is pumping
  • The size of your heart
  • How your valves are working
  • If there is any fluid around your heart
  • If there are any blood clots inside your heart
  • If there are any problems with your heart’s major blood vessels such as your aorta

How is an Echo performed?

You will be asked to change into a hospital gown. Three electrocardiogram (ECG) dots will be attached to your chest to record your heart tracing during the examination. The echo technician or cardiologist will ask you to lie on the bed and turn onto your left side. Ultrasound gel will be placed on your chest and the ultrasound probe will be placed onto your chest directly to obtain accurate pictures of your heart. You may hear a pulsing “whoosh” sound, which is the machine recording the blood flowing through your heart.

Most echocardiograms take less than an hour, but the timing of your test may vary depending on your condition. Once the test is over, the gel is wiped off and the electrodes are removed.

Should I do any special preparation for an Echo?

No special preparation is necessary for a standard echocardiogram. Wearing comfortable two-piece clothing will make the procedure easier. You eat and drink normally before and after the test. Continue to take your usual medication.

Are there any risks associated with an Echo?

Aside of some usually minor discomfort associated with the probe being placed on the chest there is no known risk. Similar ultrasound is used to examine babies inside the mother’s womb.

What happens after an echocardiogram?

You can return to your normal activities immediately after an echo procedure. Your doctor will make a follow-up appointment with you to discuss the results of your echo and determine the best treatment for you.
