A Trans-Esophageal Echocardiogram (TEE) is a special test that allows the cardiologist to record ultrasound images of your heart from inside your esophagus (food pipe). Since the esophagus lies just behind your heart, the TEE may produce clearer pictures of the heart’s movement than would standard echocardiography taken on the outside of your chest. During TEE, harmless sound waves bounce (echo) off your heart. These sound waves create images of your heart as it pumps blood through the valves and chambers. These images help your doctor identify and treat problems such as infection, disease or defects in your heart’s walls or valves. During this test, the cardiologist will help you swallow a flexible tube. This tube will pass through your throat and into your esophagus, where it can be used to take pictures of your heart. The procedure is done on an outpatient basis in hospital. An intravenous line (IV) will be placed in your arm to administer fluids and medications to help you relax. Your heart rhythm, blood pressure, breathing, and oxygen level will be monitored throughout the procedure. The cardiologist will numb your throat with an anesthetic spray so you can swallow the tube without gagging. You may feel the doctor moving the probe, but it should not be painful or interfere with your breathing.
