Transthoracic Echocardiography (TTE)
A standard echocardiogram is also known as a transthoracic echocardiogram (TTE), or cardiac ultrasound. During a transthoracic echocardiogram (TTE), a technologist (sonographer) obtains views of your heart by moving a small instrument called a transducer to different locations on your chest or abdominal wall. The transducer, which looks like a microphone, sends sound waves into the chest and picks up echos that reflect off different parts of the heart. The TTE gives your doctor a very accurate and quick assessment of the overall health of your heart.
