In a transesophageal echocardiogram, a transducer is inserted
through the mouth and down the throat into the esophagus. High-pitched sound
waves (ultrasound) are sent through the transducer to produce an image of the
heart and sometimes the aorta.
Normally the transducer is moved over the surface of the skin on
A transesophageal echocardiogram is often used for obese people
because evaluating the heart through a thick chest wall is hard. This
method allows a clear view of the valves and their ability to function. It
provides a better view of heart valves than a standard transthoracic
echocardiogram, but the procedure is more complicated.
