Transesophageal ECHO -This is an alternative way to perform an echocardiogram. A specialized probe containing an ultrasound transducer at its tip is passed into the patient’s esophagus. This allows image and Doppler evaluation which can be recorded. This is known as a transesophageal echocardiogram, or TOE (TEE in the United States). Transesophageal echocardiograms are most often utilized when transthoracic images are suboptimal and when a more clear and precise image is needed for assessment. This test is performed in the presence of a cardiologist, registered nurse, and ultrasound technician.
