ACS Q&A – Dr. Fileccia: What Happens During a Transesophageal Echo?

A transesophageal echocardiogram, commonly called a TEE, is an ultrasound of the heart performed from inside the body. While most echocardiograms are performed from outside the chest, a TEE allows physicians to obtain detailed images from inside the esophagus.

During the procedure, the patient comes to an outpatient surgery center or to the hospital. A small IV is placed in the hand or arm so that sedation can be administered. Medications (such as Versed or propofol) are commonly used to help the patient relax and sleep during the procedure.

Once the patient is sedated, a small tube is passed through the mouth and into the esophagus (the food pipe located behind the heart). An ultrasound probe at the end of the tube sends sound waves to the heart, allowing us to capture detailed images.

The procedure typically takes about seven to 10 minutes. During that time, the tube can be moved up, down and from side to side to obtain the best possible views of the heart.

After the images have been collected, the tube is removed. The patient is then allowed to wake up. Patients are usually monitored for about an hour before they are able to go home.
