Transesophageal Echocardiography (TEE)
TEE uses transducer positioned on an endoscope (a long, thin, flexible instrument). The endoscope is placed into your mouth and passed into your esophagus (“food pipe” leading from mouth to the stomach) to provide close look at your heart’s valves and chambers without interference from the rib or lungs.
TEE is often used when the results from tranthoracic (standard) echo study are not sufficient or when your doctor wants a closer look at your heart.
Your doctor uses the TEE to:
- Assess function of your heart's chambers and valves
- Determine the presence of many types of heart disease (such as valvular heart disease, myocardial disease, pericardial disease, cardiac masses and congenital heart disease)
- Evaluate the effectiveness of medical or surgical treatments
- Evaluate abnormalities of the left atrium and clots in the heart
- You will need to change into a hospital gown to wear during the procedure. Do not bring valuables.
- DO NOT eat or drink anything for at least 6 hours before the test. Take your medications with only a small sip of water.
- Take all of your medications at the usual times, as prescribed by your doctor.
- If you have diabetes and take medications to manage your blood sugar, ask your physician how to adjust your medications the day of your test.
- Tell your doctor if you have any problems with your esophagus (food pipe connecting mouth to the stomach), such as a difficulty to swallow, bleeding, hiatal hernia or cancer.
- You need to bring someone with you to drive you home after the test. You should not drive until the day after the procedure. Sedation given during the procedure causes drowsiness, dizziness and impairs your judgment, making it unsafe for you to drive or operate machinery.
What to expect:
The TEE procedure may take about 90 minutes.
After the procedure:
- After you have recovered from the sedation, you may go home or to your other scheduled appointments. You cannot drive yourself home after the test.
- You may feel a temporary soreness or numbness in your throat after the test.
- Wait at least one hour after the test (or until the numbness in your throat is gone) before eating or drinking. Start by drinking a cool liquid. If you have no problems drinking cool liquids, eat and drink as you normally would.
- After the cardiologist reviews your test, the results will go into your electronic medical record. Your physician will have access to the results and will discuss them with you.
Ask your doctor if you have questions about the TEE.
