HCM All Hearts Diagnostic Tools

A transesophageal echocardiogram is a test that creates images of the heart. It is similar to a standard echocardiogram, but TEEs are done through the esophagus.

A transesophageal echocardiogram (TEE) provides real-time high-resolution images of the heart. It uses the same technology as a standard echocardiogram, but the measurements are taken by placing the transducer (wand) down the throat rather than across the chest and ribs.

If it is difficult to get a clear picture of your heart, or if your doctor wants a more in-depth image than what is produced by the standard transthoracic echocardiogram, a TEE can be used. A TEE may also be used if you have thick chest walls, are obese, are using a ventilator, or if there is an unremovable barrier between the transducer and your chest. TEEs are also used to see whether a clot (a stroke risk) is present in the atrium. In a TEE, the transducer is passed down your throat into your esophagus.

Your throat may be sore for a few hours after the TEE. Contact your doctor if this does not go away within a few days. You may also have trouble swallowing and have the urge to gag after the procedure.
