What Are the Risks of Transesophageal Echocardiography?

Transesophageal echocardiography (TEE) has a very low risk of serious complications in both adults and children. To reduce your risk, your health care team will carefully check your heart rate and other vital signs during and after the test.

Some risks are associated with the medicine that might be used to help you relax during TEE. You may have a bad reaction to the medicine, problems breathing, or nausea (feeling sick to your stomach). Usually, these problems go away without treatment.

Your throat also might be sore for a few hours after the test. Although rare, the probe used during TEE can damage the esophagus (the passage leading from your mouth to your stomach).
