What To Expect Before Transesophageal Echocardiography

Transesophageal echocardiography (TEE) most often is done in a hospital. You usually will need to fast (not eat or drink) for several hours prior to the test. Your doctor will let you know exactly how long you should fast.

You should let your doctor know whether you're taking any blood-thinning medicines, have trouble swallowing, or are allergic to any medicines. If you have dentures or oral prostheses, you'll need to remove them before the test.

You may be given medicine to help you relax during TEE. If so, you'll have to arrange for a ride home after the test because the medicine can make you sleepy.

Talk with your doctor about whether you need to take any special steps before having TEE. Your doctor can tell you whether you need to change how you take your regular medicines on the day of the test or whether you need to make other changes.
