A transthoracic echocardiogram (TTE) is a non-invasive test that uses ultrasound to produce detailed moving images of the heart. It is the most commonly performed cardiac imaging test and provides a wealth of information about the heart’s structure and function.
Why is it Done?
An echocardiogram is used to:
- assess the pumping function of the heart (ejection fraction)
- examine the heart valves for leakiness or narrowing
- measure the size of the heart’s chambers
- look for fluid around the heart (pericardial effusion)
- identify structural abnormalities
What to Expect
You will lie on an examination table and a small amount of gel will be applied to your chest to help transmit the sound waves. A technician will gently move a handheld probe (transducer) across your chest to capture images from different angles. The test takes 30–45 minutes. You will hear a ‘whooshing’ sound during the scan — this is the sound of blood moving through your heart. The test is completely painless.
Is it Safe?
Yes. An echocardiogram uses sound waves, not radiation, and carries no risks.
