Transthoracic Echocardiogram (TTE)
What is a transthoracic echocardiogram?
A transthoracic echocardiogram (TTE) is the most common noninvasive type of echocardiogram, which uses high frequency soundwaves (ultrasound) to create a moving picture of your heart through the chest wall.
This test is used to examine suspected problems with the valves or chambers of the heart, as well as the heart’s ability to pump blood. An important purpose is to identify potential causes of stroke.
The test also may be used to:
- Estimate the amount of blood pumped out of the left ventricle with each heartbeat
- Evaluate heart size and heart valve function
- Identify areas of poor blood flow in the heart and areas of heart muscle that are not contracting normally
- Examine previous injury to the heart muscle caused by impaired blood flow or evidence of congestive heart failure
