Transesophageal Echocardiogram

Explanation of the Test

This test is designed to give your doctor more information about the working of your heart.

A long probe is inserted through the mouth and down the esophagus. A small transducer at the end of the probe sends out high frequency sound waves (ultrasound). These sound waves bounce off heart structures and are received by the transducer. The sound waves, which cannot be heard, are used to form a picture of your heart as it beats. This picture is then displayed on a TV monitor and recorded on videotape as well as paper to create a permanent record.

During the test, you will be asked to lie on your side. Your throat is sprayed with an anesthetic to numb it and you will be given a sedative through an intravenous (IV) line in the arm to help you relax. Antibiotics may also be given to help prevent infection. As you swallow, the doctor will slowly insert the probe into your mouth. You may gag a little when the probe first enters but the procedure generally is not painful.
