A transesophageal echocardiogram (TEE) records ultrasound images of your heart.
The transducer, about the size of a normal piece of food, is mounted on the end of a flexible tube, about the size of your index finger. The tube is placed in your mouth and guided down your esophagus (swallowing tube).
You will be given medicine to help numb the back of your throat. This will make swallowing the tube easier.
The TEE gives excellent pictures of your heart because the heart is next to your esophagus.
The procedure will take 1½ to 2 hours.
