Transesophogeal Echocardiography (TEE)
Like a routine echocardiogram, TEE uses ultrasound to create images. TEE images, however, are clearer because they are taken with a scope from inside your body. Your doctor may order a TEE if the routine echocardiogram cannot answer all of the questions about your heart's structure and function. TEE involves passing a special ultrasound scope through your mouth into your food pipe (esophagus) to take pictures.
