Transesophageal echocardiography is a procedure which is used to detect abnormalities of the heart valves or artificial valves. An endoscope, with a transducer at the tip, is guided down your esophagus. Visualization is improved because the transducer is closer to the heart. Images of your heart are then obtained. The transducer collects sound waves, which are recorded on tape.
Your physician can then read the results and design the best plan of treatment for you.
