Transesophageal Echocardiography

by Kohnle D


Echocardiography uses sound waves to make images of the heart. In transesophageal echocardiography, the ultrasound probe is passed down the throat and in to the esophagus. The esophagus is the tube that goes from the throat to the stomach. The esophagus sits very close to the heart. This method allows for clearer images of the heart than other methods.
