Transesophageal Echocardiogram (TEE)
A cardiologist will sometimes perform a TEE if the routine echocardiogram does not provide all of the necessary information. By passing a flexible tube about the size of your index finger through your mouth and down into your esophagus, the cardiologist is able to look at images of your heart from inside your esophagus. Because the esophagus lies just behind the heart, a TEE may produce clearer pictures of the heart than a standard ECHO. Your throat is numbed and you are sedated to keep you comfortable during the test.
In preparation for the TEE, you should not eat or drink after midnight on the day prior to the test. Also, because sedation is given during the test, someone will need to drive you home after the test.
