Transesophageal Echocardiogram (TEE)
Transesophageal echocardiography (TEE) uses high-frequency sound waves (ultrasound) to make detailed pictures of your heart and the arteries that lead to and from it. Unlike a standard echocardiogram, the echo transducer that produces the sound waves for TEE is attached to a thin tube that passes through your mouth, down your throat and into your esophagus. Because the esophagus is so close to the upper chambers of the heart, very clear images of those heart structures and valves can be obtained. TEE is typically recommended when the physician wants to examine the heart valves and chambers closely, check for blood clots in the heart, or visualize the left upper chambers of the heart.
