Transesophageal Echocardiography (TEE)

TEE provides views and excellent definition of the heart that cannot be obtained with conventional echocardiography. This is also used to view difficult to examine hearts (if the patient is obese or has a thick chest wall). To perform the test, an intravenous (IV) line will be inserted into a vein in your arm to allow injection of drugs such as sedatives or antibiotics. A viewing tube and small transducer are passed down the esophagus, allowing us to transmit sound waves to the heart from inside the body. After the transducer is positioned behind the heart, it can then be manipulated to produce images of the heart chambers and other structures. This test monitors heart functions during cardiac surgery and detects blood clots in the left atrium.

Preparing for the Test:

• Do not eat or drink for 6 hours before the procedure - your stomach must be empty.
• If you are diabetic, contact your doctor for instructions regarding diet and medications before your scheduled test day.
• Have someone drive you to the test. Also arrange to have someone drive you home afterwards. Do not plan to drive yourself home, as you may be drowsy.
• Tell the doctor if you have any conditions involving your esophagus or stomach, or if you have a problem swallowing.
• Tell the doctor or nurse if you have allergies to any medications, especially sedatives (medications that help you relax).
• If you wear dentures or oral prostheses, you will need to remove them, as they can interfere with the test.
• Before the test, you’ll be given a brief explanation of the test and you’ll be asked to sign a consent form. Feel free to ask any questions about the procedure.
