Tests and Procedures

Transesophageal Echocardiogram (TEE)

A Transesophageal Echocardiogram, commonly called TEE, is a diagnostic procedure using an ultrasound. The procedure involves passing a probe (transducer) through your mouth and down the esophagus. The probe will allow the physician to view your heart from the esophagus. A spray will be applied to the back of your throat to assist you in swallowing the probe and to reduce your gag reflex. You will be given a small amount of medication to help you relax. You will be conscious throughout the entire procedure and able to understand instructions and comments from the physician.

You will lie on your side during this 30-minute procedure. A registered nurse, ultrasound technologist, and a physician will be in attendance. Your family or support person will be escorted to a nearby waiting area. Upon completion of the procedure, they may rejoin you.

You will be required to stay in the procedure/recovery area until you are able to demonstrate your ability to swallow without difficulty, and the effect of the spray in your throat has worn off.
