Transesophageal Echocardiogram

Your healthcare provider will talk to you about how to prepare for surgery. You may be told not to eat or drink anything after midnight on the day of your surgery. You will be told what medicines to take or not take on the day of your surgery.

You will lie down with your chin bent down to touch your chest. A mouthguard will be put into your mouth. The mouthguard keeps you from biting down on the tools that are put into your mouth.

An ultrasound probe will be put into your mouth and down your throat. The probe is a long, thin, bendable tube with a transducer on the end. You may be asked to swallow several times as it is moved down your throat. The transducer is a small transmitter that sends sound waves to your heart. The sound waves can travel around your heart so pictures of your heart will show up clearly. The TEE usually takes less than 45 minutes.
