Transesophageal
Echocardiogram (TEE)
What is a Transesophageal
Echocardiogram (TEE)? A TEE is
an ultrasound test that examines the heart and it’s structures. The TEE is a
special form of ultrasound testing that is done through the esophagus (the tube
leading from the mouth to the stomach). By placing the special ultrasound probe
(especially made to be placed in the esophagus) in the esophagus the doctor
performing the test is able to obtain very clear and detailed pictures of your
heart. This will enable him/her to determine with great confidence if the cause
of your symptoms are coming from your heart.
How
does the TEE work? First,
the physician in charge of your test will determine if there exist any reason
why you should not have the test. He/she will also ask you questions to find out
why you are having the test. This is necessary because many times the physician
ordering the test is not the same doctor performing the test. After this the
physician in charge will give a sedative to help you to relax and to numb your
swallowing reflex. This will enable the special probe (about the size of a small
finger) to easily pass into your esophagus. Throughout the entire procedure you
are closely monitored by a RN and a specially trained echo technician to ensure
your safety.
Once the probe is in place, sound
waves coming from the special probe reflect off of your heart (echo), return to
the probe which turns the sound waves into very detailed images of your heart.
The images actually show your heart beating and all the valves opening and
closing as will as the blood flowing through your heart. It will also show if
there are any abnormal structures or objects (such as a blood clot) in your
heart. All of this will be displayed on a monitor and recorded on tape so the
physician can review all the findings and store the images for any future
reference. The entire length of the test should take 90 minutes, with the probe
being inserted for about 10-15 minutes.
Are
there any special preparations for the test? Yes,
there are several things you will have to do before the test.
1.
Do not eat or drink for 6
hours before the test. This is to ensure that your stomach is empty during the
test. You may have sips of water to take your medicine.
2.
If your test has been
scheduled as an outpatient procedure, make sure someone drives you to the
hospital. Due to the medication used during the test, you will probably be
drowsy after the test and not able to drive.
3.
Make sure you tell the
doctor in charge of the test if you have had any problems in the past with
swallowing or problems with your esophagus or stomach.
4.
If you wear dentures or
oral prostheses, you will need to remove before the test.
Is
the TEE safe? Because the
special probe is inserted into the esophagus there are some risk to this
procedure. These include breathing problems, abnormal heart rhythms, infection
of the heart valves, bleeding, reaction to the medicines given and very rare
instances of damaging the esophagus. If you have questions, talk with your
physician before the test.
Why
is a TEE done? There are
several reasons why you doctor may have determined that you need a TEE. Some of
the more common reasons are:
♥
to find blood clots too small to see with a surface echo.
♥ to locate any abnormal
masses
♥ to examine artificial valves
♥ to look for any infection in
the heart
♥ to look for any tears and
holes in the heart
♥ When the surface echo is of
inadequate quality due to obesity or chronic lung disease.
Where
do you go once you arrive at the hospital? Once
at the hospital, go to Central Registration on the ground floor. After you
register, they will give you directions to the Endoscopy unit of 3 West. Your
family and friends will be able to wait in the waiting room on the Endoscopy
unit.
What
are the benefits of the test? Images
obtained from TEE are often much clearer than images obtained from regular
surface echo’s. This will enable the physician to accurately diagnose your
complaints and give recommendations for any appropriate treatment.
