An echocardiogram is a test that uses sound waves to create a moving picture of the heart. The picture is much more detailed than a plain x-ray image and involves no radiation exposure.

There is no special preparation for the test. For a TEE, you will be asked not to eat or drink for several hours before the test.
You will be asked to remove your clothes from the waist up and lie on an examination table on your back. Electrodes will be placed on your chest to allow for an ECG to be done. A gel will be spread on your chest and then the transducer will be applied. You will feel a slight pressure on your chest from the transducer. You may be asked to breathe in a certain way or to roll over onto your left side.
A normal echocardiogram reveals normal heart valves and chambers and normal heart wall movement.
An abnormal echocardiogram can mean many things. Some abnormalities are very minor and do not pose significant risks. Other abnormalities are signs of very serious heart disease that will require further evaluation by a specialist. Therefore, it is very important to discuss the results of your echocardiogram in depth with your health care provider.
There are no known risks associated with this test.
Abnormal results may indicate heart valve disease, cardiomyopathy, pericardial effusion, or other heart abnormalities. This test may also be performed for the following conditions:
