What is a transthoracic echocardiogram (TTE)?
An echocardiogram (also called an echo) uses sound waves to make an image of your heart. A device called a transducer sends sound waves that echo off your heart and back to the transducer. These echoes are turned into moving pictures of your heart that can be seen on a video screen.
In a transthoracic echocardiogram (TTE), the transducer is moved across your chest or belly. A TTE is the most common type of echocardiogram.
Why is a transthoracic echocardiogram (TTE) done?
This test is done to check your heart health. It's used for many reasons. For example, it may be done to:
- Check a heart murmur.
- Look for the cause of shortness of breath or unexplained chest pain or pressure.
- Check how well your heart is pumping blood.
- Check to see how well your heart valves are working.
- Look for blood clots inside your heart.
- Measure the size and shape of the heart's chambers.
- Measure the blood pressure and speed of blood flow through the heart.
How is a transthoracic echocardiogram (TTE) done for children?
- Your child may be asked to remove their clothes above the waist. Your child may be given a cloth or paper covering to use during the test.
- Your child will lie on their back or left side on a bed or table.
- Your child may receive medicine through a vein (intravenously, or I.V.). The I.V. can be used to give your child a contrast material. This helps your doctor get good views of the heart.
- Small pads or patches (electrodes) will be placed on the skin of your child's chest to record the heart rate during the test.
- A small amount of gel will be rubbed on the side of your child's chest to help pick up the sound waves.
- The transducer will be pressed firmly against your child's chest and moved slowly back and forth. It is usually moved to different areas on the chest or belly to get specific views of your child's heart.
- Your child will be asked to do several things, such as hold very still, breathe in and out very slowly, hold their breath, or lie on their left side.
- When the test is over, the gel is wiped off and the electrodes are removed.
How do you prepare for a transthoracic echocardiogram (TTE)?
You don't need to do anything to prepare. It may help to wear comfortable clothing that you can easily take off.
