What is a transesophageal echocardiogram (TEE)?
The transesophageal echocardiogram (TEE) is a specialized type of echocardiogram test that uses an ultrasound to create a visual picture of your heart and surrounding blood vessels. This test is conducted by inserting a special probe into your esophagus (while you are sedated), to take a clearer picture of your heart. It is a valuable test that provides important information for the evaluation and treatment of various heart conditions.
Who needs a TEE?
Your cardiologist may order a TEE for you if the standard echocardiogram didn’t provide a clear picture of your heart, such as evaluating cardiac valve function, if your doctor suspects you may have a blood clot or heart abnormality or assessing the source of an embolism, which is a blood clot that has traveled to other parts of your body. It can also be used in conjunction with heart surgery or other surgical procedures to guide the surgeon.
What are the risks of a TEE?
The risks associated with a TEE are relatively low, however complications can occur. It’s important to discuss any concerns with your healthcare team prior to your procedure.
You may experience some discomfort, although the sedation you receive will help to minimize any discomfort. Your ability to breath may, in rare cases, temporarily be impacted due to the close proximity of the esophagus to the trachea (or windpipe). Your healthcare team will monitor this closely. Because you are sedated, there is a small risk of aspiration (inhaling the contents of your stomach), which is why fasting is always advised prior to a TEE.
There is also a small risk of injury to your throat, allergic reaction, infection or other complications, all of which you will be informed of prior to your procedure. It’s important to discuss any concerns you have with your healthcare team before undergoing sedation.
How do you prepare for a TEE?
You should always consult with your doctor about specific instructions before a transesophageal echocardiogram, but you will usually be asked to fast at least a few hours before the procedure to ensure there is nothing in your stomach.
What should you expect from a TEE?
You will be given a sedative to help you relax and minimize any discomfort related to the procedure. Then a small ultrasound transducer is attached to an esophagoscope, which is a thin flexible tube, and passed through your mouth and into your esophagus. Doing so allows for your healthcare team to obtain very clear images of your heart.
You may receive an IV which will provide sedation and fluids during your test. Electrodes will be placed on your best to monitor you. The ultrasound transducer will emit sound waves which will bounce off your heart and create detailed images for your doctor to read. Once enough images are captured, your healthcare team will carefully remove your esophagoscope and monitor you closely as you come out of sedation.
