What Is a Transesophageal Echocardiograph?
A transesophageal echocardiograph (TEE) is a medical imaging procedure used to obtain detailed images of the heart and its structures. Unlike a traditional echocardiogram, where the ultrasound probe is placed on the chest, a TEE involves the insertion of a small probe into the esophagus, which lies directly behind the heart. This method allows for much clearer and more precise imaging of the heart, as the esophagus is in close proximity to the heart, providing a better view compared to external ultrasound imaging. TEE is particularly useful for visualizing areas that are difficult to assess with a traditional echocardiogram, such as the heart valves, atria, and aorta.
The procedure is often performed when more detailed information is needed for diagnosing heart conditions such as valvular heart disease, infective endocarditis, atrial fibrillation, or aortic aneurysms. TEE can also be used to guide medical procedures or monitor heart function during surgery. The patient is typically given a sedative or local anesthesia to ensure comfort, as the procedure involves inserting a tube into the esophagus. Though generally considered safe, TEE can have risks such as sore throat, gagging, or, in rare cases, complications like esophageal injury. The procedure usually takes around 30-60 minutes, and patients can typically return to normal activities after a brief recovery period.
