What is transesophageal echocardiography?
Transesophageal echocardiography is also known as TEE, or heart scan with endoscopy. TEE uses a small probe guided into the esophagus while a child is sedated to closely evaluate the heart and blood vessels within the chest. Echocardiography is a procedure used to assess the heart’s function and structures through the use of sound waves. A transducer (similar to a microphone) sends out ultrasonic sound waves at a frequency too high to be heard. When the transducer is placed on the chest at certain locations and angles, the ultrasonic sound waves move through the skin and other body tissues to the heart tissues, where the waves “echo” off of the heart structures. The transducer picks up the reflected waves and sends them to a computer. The computer interprets the echoes into an image of the heart walls and valves. Transesophageal echocardiography (TEE) uses a probe with a transducer on the end that is guided through the throat and into the esophagus while your child is sedated. The TEE
