Tee Test
Transesophageal echocardiography (TEE) is an ultrasound technology that provides highly detailed images of the heart and its internal structures.
Our heart experts use TEE to detect blood clots, evaluate heart valves, and guide treatment for arrhythmias (abnormal heartbeats) and many other heart conditions.
About Transesophageal Echocardiogram (TEE)
A transesophageal echocardiogram (TEE) is an imaging test that uses sound waves to produce high-quality, moving pictures of the heart. An echocardiogram (echo) shows the size and shape of the heart and details of the heart’s internal structures.
Because your heart is just in front of the esophagus, a TEE provides clearer, more detailed images of the left chambers of the heart than a standard echo, which we perform on the surface of your chest. Learn more about echocardiography at Stanford.
We use TEE to:
- Assess how well the heart’s chambers, valves, and blood vessels are working, for proper blood flow through the heart
- Check for blood clots in the heart, to guide treatment for atrial fibrillation, a type of arrhythmia (abnormal heartbeat)
- Check for structural abnormalities in heart valves and chamber walls
- Guide the positioning of catheters in many diagnostic and treatment procedures
