Echocardiography uses sound waves to make images of the heart. In transesophageal echocardiography (TEE), the ultrasound probe is passed down the throat and in to the esophagus.

What to Expect
Prior to Procedure
You will be given a mild sedative through an IV. You will be sleepy throughout the procedure. A topical anesthetic may also be applied to the back of the throat. This will numb the throat.
Description of the Procedure
You will be asked to lie on your side in a hospital gown. The ultrasound probe will be slid down your throat and into the esophagus until it is near the heart. The device will create active images of the heart. When the imaging is done, the probe will be taken out.
How Long Will It Take?
Will It Hurt?
There may be some mild discomfort during the procedure. Most people sleep through the procedure and remember very little of it. Your throat may be sore for a few days.
You will need a ride home from the procedure. Do not eat or drink until the numbness in your throat wears off. This will keep you from inhaling food or drink into the lungs.
Talk to your doctor about the results of the test.
