Transesophageal Echocardiogram

An echocardiogram (often called “echo”) is a graphic outline of the heart’s movement, valves and chambers. During the transesophageal echocardiogram (TEE) test, an ultrasound transducer (which produces high frequency sound waves) provides pictures of the heart’s valves and chambers and helps the physician evaluate the pumping action of the heart. The test is performed within a hospital setting under sedation.

The ultrasound transducer is positioned on an endoscope (a long, thin, flexible instrument about 1/2 inch in diameter). The endoscope is placed into your mouth and passed into your esophagus (the “food pipe” leading from your mouth into your stomach) to provide a close look at your heart’s valves and chambers without interference from the ribs or lungs.

Your doctor may use the TEE to:

* Assess the overall function of your heart’s chambers and valves

* Evaluate the effectiveness of medical or surgical treatments

* Evaluate abnormalities of the left atrium

* Determine the presence of many types of heart disease (such as valvular heart disease, myocardial or pericardial disease, possible valve infection, cardiac masses & congenital heart disease)

What to Expect: Before the test, a cardiac technician, nurse or physician will explain the procedure in detail, including possible complications and side effects. They will be available to answer any questions you may have. You will be given a hospital gown to wear. An intravenous (IV) line will be inserted into a vein in your arm or hand so medications can be delivered when necessary.

The nurse will connect you to several monitors: An EKG monitor, which charts your heart’s electrical activity during the test, a blood pressure monitor to monitor your blood pressure intermittently throughout the test, and an Oximeter, which is a small clip placed on your finger to monitor the oxygen level of your blood.

The doctor will put medication into your IV to help you relax and feel comfortable as possible during the test. You may feel drowsy. If you feel discomfort at any time during the test, tell your doctor, nurse, or sonographer/technician. You will be asked to lie on your left side on an exam table. A dental suction tip will be placed in your mouth to remove any secretions.

The doctor will insert a thin, lubricated endoscope into your mouth and down your throat (this part lasts a few seconds and might be a little uncomfortable) into your esophagus. The tube does not interfere with your breathing. You may be asked to swallow at certain times to help pass the tube.

Once the probe is in position, pictures of the heart are obtained at various angles (you will not feel this part of the test). Because of the sedative, you may not be entirely awake for the test. Your heart rate, blood pressure and oxygen level of your blood will be closely monitored during and immediately after the exam. The TEE takes approximately 90 minutes for preparation and procedure.

Preparation: You can wear whatever you like. You will need to change into a hospital gown to wear during the procedure. DO NOT eat or drink anything for at least eight 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 (tube connecting mouth to the stomach), such as hiatal hernia, problems swallowing, or cancer.

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.

After you have recovered from the sedation, you may go home or to your other scheduled appointments. You may NOT 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.
