Transoesophageal Echocardiography

A transesophageal echocardiogram (TEE) is an imaging test that uses sound waves to produce high-quality, moving pictures of the heart. An echocardiogram (echo) shows the size and shape of the heart and details of the heart’s internal structures.

For a TEE, an imaging technologist guides the transducer (sonogram device in the shape of a thin, flexible tube) into your mouth and down your esophagus to obtain the images. You will take medication to help you relax and to numb your throat so that you will not feel discomfort during the procedure.
