Transesophageal (tranz-ih-sof-uh-JEE-ul) echocardiography (EK-o-kar-de-OG-rah-fee), or TEE, is a test that uses sound waves to create high-quality moving pictures of the heart and its blood vessels. TEE is a type of echocardiography (echo). Echo shows the size and shape of the heart and how well the heart chambers and valves are working. Echo can pinpoint areas of heart muscle that aren't contracting well because of poor blood flow or injury from a previous heart attack.
