What is a transesophageal echocardiogram?
A transesophageal echocardiogram (TEE) is a special echocardiographic examination that allows cardiologists to look at the heart "from the inside out." Because many of the important structures in the heart are posterior, close to the esophagus, some of the best images can be obtained by imaging from the esophagus.
How is a transesophageal echocardiogram performed?
A transesophageal echo is performed by the patient swallowing a small tube (about the size of a finger). This is very similar to an upper endoscopy procedure. The patient is sedated and the back of the throat is anesthetized with a topical anesthetic. The cardiologists performing the test are assisted by a nurse. The test itself usually takes 10-20 minutes, but patients should expect the entire procedure to take about 90 minutes in order to account for recovery time.
Is a transesophageal echocardiogram dangerous?
Transesophageal echocardiography is quite safe, although as with all medical procedures, there can be risks. The most common risk associated with TEE is irritation to the back of the throat. Serious complications from TEE occur extremely rarely (< 1 in 10,000).
