Transesophageal Echocardiogram


A Transesophageal Echocardiogram is another form of Echocardiogram. It uses an ultrasound tube which goes through your mouth and throat and is easy to swallow. Ultrasound uses sound waves, or echoes, to make the picture. It allows us to see clear pictures of your heart and related structures from the inside of your body. Your heart doctor (Cardiologist) may have you take this exam if good pictures cannot be made during a standard Echocardiogram.
