A transesophageal echocardiogram is a test to help your doctor look at the inside of your heart. A small device called a transducer directs sound waves toward your heart. The sound waves make a picture of the heart's valves and chambers.
Your doctor may do this test to look for certain types of heart disease. Or it may be done to see how disease is affecting your heart.
You will be given medicine to make you sleepy and comfortable during the test.
The doctor puts a small, flexible tube into your throat and guides it to the esophagus. This is the tube that connects your mouth to your stomach. The doctor will ask you to swallow as the tube goes down.
The transducer is at the tip of the tube. It gets close to your heart to make clear pictures. The doctor will look at the pictures on a screen.
You will not be able to eat or drink until the numbness from the throat spray wears off. Your throat may be sore for a few days after the test.
Transesophageal echocardiogram (TEE) may be done to:
Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.
Before a TEE, your throat may be numbed with an anesthetic spray, gargle, or lozenge. This is to relax your gag reflex and to make it easier to insert the probe. Shortly before the procedure starts, an IV line will be placed in a vein in your arm. Medicine to decrease saliva and stomach secretions may be given through the IV. A pain medicine and sedative will be given to you through the IV in your arm during the procedure. You should feel relaxed and drowsy but still alert enough to co-operate.
Your heart rate, breathing rate, and blood pressure will be monitored throughout the procedure. Also, a small device used to measure the amount of oxygen in your blood (pulse oximeter) may be attached to your finger or earlobe.
You will be asked to lie on your left side with your head tilted slightly forward. A mouth guard may be inserted to protect your teeth from the probe. Then the lubricated tip of the probe will be guided into your mouth while your doctor gently presses your tongue out of the way. You may be asked to swallow to help move the tube along. It may be helpful to remember that the probe is no thicker than many foods you swallow. When the probe is in your esophagus, it will be moved down gently to the level of your upper right heart chamber (atrium), and ultrasound images will be taken. You won't feel or hear the sound waves during the test.
During the procedure, try not to swallow unless you are asked. An assistant may remove the saliva from your mouth with a suction device. Or you can just let the saliva drain from the side of your mouth. A transesophageal echo is generally painless. But you might feel nauseated and uncomfortable while the probe is in your throat.
The test may take about 30 to 60 minutes. The probe may be in your esophagus for about 10 to 20 minutes.
After the test, you may have a tickling, dry throat; slight hoarseness; or a mild sore throat. These symptoms may last for 2 to 3 days.
A transesophageal echocardiogram (TEE) can sometimes cause:
Insertion of the probe may tear or puncture your esophagus. This is rare.
Results are usually available within one day. If the test is done by a cardiologist, the results may be available immediately after the test.
The heart chambers and walls of the heart are of normal size and thickness, and they move normally.
Heart valves are working normally, with no leaks or narrowing. There is no sign of infection.
The amount of blood pumped from the left ventricle with each heartbeat (ejection fraction) is normal.
There is no excess fluid in the sac surrounding the heart, and the lining around the heart is not thickened.
There are no tumours and blood clots in the heart chambers.
Heart chambers are too big. The walls of the heart are thicker or thinner than normal. A thin heart wall may mean poor blood flow to the heart muscle or an old heart attack. A thin, bulging area of the heart wall may indicate a bulge in the ventricle (ventricular aneurysm). The heart muscle walls do not move normally because of a decreased blood supply from narrowed coronary arteries.
One or more heart valves do not open or close properly (are leaking) or do not look normal. Signs of infection are present.
The amount of blood pumped from the left ventricle with each heartbeat (ejection fraction) is lower than normal.
There is fluid around the heart (pericardial effusion). The lining around the heart is too thick.
A tumour or blood clot may be found in the heart.
