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.
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.
