Use of transesophageal echocardiography in evaluating coronary arteries.

Because of the better resolution of higher frequency transducers and the proximity of the coronary arteries to the esophageal window, TEE is emerging as a valuable method for evaluation of coronary artery disease. TEE allows imaging of the proximal coronary arteries, measurement of coronary flow reserve, identification of coronary artery anomalies, and observation of wall motion during transesophageal atrial pacing. The application of TEE in evaluation of coronary artery disease will continue to grow as technology improves.
