Transesophageal Echocardiogram (TEE)

What is a Transesophageal Echocardiogram?

• An echocardiogram is a test that uses ultrasound (sound waves or sonar) to evaluate the structures of the heart and how well the heart is working.
• A transducer, which is attached to the end of a thin flexible tube, is passed through the mouth and into the esophagus. (the feeding tube that connects the mouth and stomach)
• Once positioned, images can be obtained of the valves and chambers of the heart without the interference of the ribs, lungs, and skin.
• A Registered Nurse inserts an intravenous line and a small amount of medication is given to sedate and relax the patient, and make them unaware of any discomfort during the procedure.
• The patient will be positioned on their left side during the procedure.
• Electrodes are applied to the chest to monitor the heart rate and rhythm.
• A blood pressure cuff is placed on one arm to monitor the blood pressure.
• A small clip like device is placed on one finger to measure blood oxygenation.
• Preparation, the actual test, and recovery time lasts about 2 ½ hours.
