What is a TEE? (Transesophageal Echo)
A tranespohageal echo cardiogram is a procedure that utilizes ultrasound waves to examine the heart. This is a invasive procedure where a probe is inserted into the esophagus. Your esophagus is the tube that leads from your mouth to the stomach. Since your esophagus lies behind your heart, this procedure is able to give a clearer image of the heart in contrast to a regular echo cardiogram which is done on the outside of the chest,
The probe that is inserted is a long flexible tube that has a small microphone like device that is called a transducer at the tip. The transducer is the part that send ultrasound waves that bounce off different parts of the heart. The transducer picks up th reflected waves and send them to a computer. The computer shows moving images of the heart on its screen. They are able to see the flow of blood through the heart chambers and the valves of the heart.
The physician will order this test when he wants to see structures of your heart that are hard to see. During this procedure they are able to detect any blood clots that are inside the heart. Heart valves can be assessed for any defects. If they are any structural issues, such as a hole between heart chambers they will be able to visualize it with this procedure. It is also used to diagnose a tear which is known as a dissection in the lining of the aorta. It also makes it easier to visualize the heart when someone is overweight or has chronic lung disease.
During the procedure you will be asked to lay on your left side. They will spray an anesthetic to numb your throat before they insert the tube in your mouth. As you are directed to swallow the tube, it is inserted into your esophagus. You will have an IV where you will be given a sedative to help you remain calm during the procedure. While you are having this procedure done, they will monitor your heart rate, blood pressure and oxygen level. They will be able to suction any excess secretions in your mouth. The actual procedure usually takes 20 to 30 minutes..
This is a relatively safe procedure but as with all tests there is always a possibility of complications. Possible complications include:
An abnormal heart rhythm
Breathing difficulties
perforation of the esophagus
infection of the heat valves.
Your physician will discuss all these risks with you before the actual procedure is performed.
The advantage of having this test is that it gives a much clearer picture of the heart than a standard echo provides. It will help with the diagnosis of any conditions and they will be able to come up with a treatment plan. Because you have been given a sedative, you will need to have someone drive you home after the procedure. Your throat may be sore, cold drinks and throat lozenges will help. If after the procedure you develop any trouble breathing, swallowing, experience shortness of breath, chest pain, develop a fever or notice bleeding you need to call your doctor immediately.
