Echocardiography uses sound waves to make pictures of the heart. In transesophageal echocardiography (TEE), the ultrasound probe is passed down the throat to the food pipe. The food pipe is close to the heart.
Reasons for Procedure
This test is done to look for problems of the heart, such as:
- Enlarged heart
- Thickening of the heart walls
- Heart valve problems
- Blood clots
- Other conditions

- Any allergies you may have
- Current medicines, herbs, and supplements that you take and whether you need to stop taking them before the procedure
- Fasting before the procedure, such as avoiding food or drink after midnight the night before
- Whether you need a ride to and from the procedure

Description of the Procedure
You will on your side lie on a table. Slippery material will be applied to a probe. The probe will be slid down the throat into the food pipe until it is near the heart. The probe will create images of the heart. When the imaging is done, the probe will be taken out.
How Long Will It Take?
15 to 30 minutes
Will It Hurt?
There may be some mild discomfort during the procedure. Your throat may be sore for a few days.
Food and drink will need to be avoided until the throat numbness wears off.
The doctor will discuss the results of the test with you.
