Transesophageal Echocardiography Cardiology What is transesophageal echocardiography (TEE)? Trans- is a prefix which means “through� and therefore transesophageal means through the esophagus. TEE is a specialised ultrasound technique used to visualise the heart from the esophagus. A flexible probe mounted with a transducer is passed through the mouth down the esophagus. Pictures of superb clarity can be obtained this way.
What is the purpose of this test? TEE allows detailed visualisation of the structures of the heart and great vessels. It is also used to examine the structure of the heart and its blood flow. It is especially useful in patients whose Transthoracic echo (TTE) images are not optimal and when there is increased clinical suspicion of certain conditions. Preparation before the test 1. You are required to fast for at least 6 hours before the test. 2. Be accompanied by a family member when you come for the test. 3. Please notify the doctor/medical technologist of any allergies, difficulty in swallowing, or problem with your mouth, esophagus or stomach. 4. You should not undergo the test if you are not feeling well (e.g. fever, running nose). Please call our appointment centre to reschedule.
