TEE (Transesophageal Echocardiogram)

Transesophageal echocardiogram is a procedure to evaluate cardiac structures and function. It records images of the heart from inside the esophagus. TEE allows for a better view of the heart than the standard transthoracic echocardiogram. Additionally, a TEE can evaluate excess fluid in the sac around the heart, detect heart tumors and blood clots within the heart chambers. This procedure is standard prior to heart valve surgery, and cardioversion.
