TRANSESOPHAGEAL ECHOCARDIOGRAM
A transesophageal echocardiography (TEE) is a special type of echocardiogram.
Echocardiograms are diagnostic tests that use crystals to generate high-frequency sound waves. As these sound
waves are aimed at the valves and tissues of the heart, they are reflected (echoed) back to a machine that
analyzes them and generates an image of your heart on a computer monitor. Echocardiograms allow physicians
to view the chambers of your heart while it is pumping, and help physicians determine whether your valves,
pericardium (the external covering of the heart), and arteries are functioning properly.
An echocardiogram is used to diagnose a number of heart problems:

Valve disease
Coronary artery disease
Weak heart muscles
Holes between heart chambers
Fluid around the heart
Aortic abnormalities
Congenital heart defects
Emboli (small blood clot fragments)
An echocardiogram is performed while you lay on your back, and a technician moves a small device, called a
transducer, over your chest. A TEE is performed by having a cardiologist insert a probe into your esophagus.
(You will receive a mild intravenous sedative and an anesthetic spray for your throat). Your esophagus is
directly behind the heart, so viewing your heart from this angle provides very clear and detailed images. A TEE
can help physicians get a better view of blood clots, for example, that they might not see clearly in a regular
echocardiography exam.
Preparing for the Test A TEE is a little more involved than a regular echocardiogram. You will need to
abstain from food or drink for 6 hours prior to the test.
What is the doctor looking for? The test will evaluate the flow of blood through the chambers of the heart;
evaluate the function of the heart valves, and assess the condition of the great vessels in the heart. The
cardiologist is also assessing for blood clots and pump action.
What is the test? The T.E.E. test involves a probe being placed into your esophagus (the "tube" through which
food reaches your stomach). The probe then uses sound waves to produce an image of blood flowing through
the heart. The images are recorded on video tape and are of high quality with superior detail. Our physician uses
this information to determine the best treatment plan for you.
During the Procedure: A nurse will start an intravenous (IV) feeding in your arm so that medications can be
easily administered during the test. You will be connected to equipment that will monitor your heart rate and
blood pressure. Another device, a pulse oximeter, which is like a bandaid, will be connected to your finger, to
monitor oxygen levels in your blood. You will be given some medications to help you relax. Your throat will be
sprayed to make it numb before the T.E.E. probe is inserted. A special device will be placed in your mouth to
prevent you from accidentally biting the probe. This mouthpiece restricts the motion of the tongue, making
it difficult to speak. (The device does not interfere with your breathing.) During this time - which lasts about 15
minutes - the doctor and nurse will ask you questions, which you will be able to answer by gently nodding or
shaking your head.
After the Procedure: You will remain there until the numbing spray and other medications wear off (usually
one or two hours). The nurses in the recovery area will take care of you and check on you frequently.
Going Home : When the medications wear off the nurses will provide you with discharge instructions and will
inform you that you can return home. It is important to have a family member or friend take you home since
lingering effects of the medications may interfere with your ability to drive safely.
Where are the tests done? Your T.E.E. exam will take place in the hospital.
May I eat or drink? Do not eat or drink anything for 6 hours before your test.
What about medications? Check with your doctor about any medications you are taking. If you are diabetic,
ask your doctor about diet changes and/or altered dose of diabetic medications.
Will I have an IV? Yes
Do I need special clothing? No
What else should I bring to the test? A list of your current prescribed medications. Physician Request for
exam. Eyeglasses to read the consent form.
How long does the test take? The probe is in the esophagus for about 15 minutes.
When will the results be ready? The physician knows immediately and will report to you and the family. A
written report will follow within 24-48 hours.
Tell your doctor/nurse if you have … Any symptoms or are experiencing any discomfort or anything wrong
with your esophagus.
Will the test make me sick or sleepy? You may experience a gagging reflex. The test may give you a sore
throat. You will probably be sleepy from medication given for sedation. This will usually wear off within 1
hour. You cannot drive home from the test. You must have someone to take you home.
Will I receive any radiation during the procedure? No
What if I am pregnant or breast-feeding? There are no risks if you are pregnant or breast-feeding.
