What is a transthoracic echocardiogram?
During a transthoracic echocardiogram (TTE), a technician obtains views of the heart by moving a small instrument called a transducer to different locations on the chest or abdominal wall. A transducer, which resembles a microphone, sends sound waves into the chest and picks up echos that reflect off different parts of the heart.
There is no special preparation for the TTE.
What happens after the test?
When the test is over, the gel is wiped off and the electrodes are removed.
Are there any side effects?
There are no known risks from a TTE. However, during the test the technician may have to press hard on your chest with the transducer. Tell the technician if you feel any pain or discomfort.
