What to Expect
Prior to Procedure
- Avoid alcohol for several days before the procedure. Alcohol may interfere with the type of sedative used.
- Do not eat or drink for 4-8 hours before the 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 patients 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. Be sure to follow your doctor’s instructions.
Talk to your doctor about the results of the test.
