Diagnostic examinations

Transesophageal echocardiography

A transesophageal echo, also called a TEE or TOE, is a special kind of ultrasound that takes pictures of the heart. Unlike a regular ultrasound that glides on the chest, a TEE uses a thin tube placed down the throat (similar to gastroscopy) to get a closer and more detailed look at the heart.

This helps us see things like heart valves or to detect a thrombus in the heart (especially in patients with atrial fibrillation).

At CardioHealth Center, we can alsoperform 3-dimensional transesophageal echocardiography (3D TOE). This technique requires special high-end equipment as well as special training of the doctor performing it. 3D TOE offers even more detailed images of the heart. It is a powerful tool in assessment of valves, the need of intervention on them and the preparation of such interventions.

During the exam we use a local throat spray to numb the throat so that no pain is felt during the procedure. We also administer a small dose of sedative medications to help patients relax and make the procedure more comfortable.

To prepare for a TEE patietns are asked not to eat or drink for 4 - 6 hours before the exam and to take any prescribed medications with only a sip of water. The patient should also arrange to have someone drive them home after the exam in case they are feeling drowsy.
