title: Transesophageal echocardiography.
abstract: Transesophageal echocardiography has provided a new acoustic window to the heart, the great vessels, and the mediastinum.  It provides anatomical, functional hemodynamic, and blood flow information. High-quality visualization of left atrial appendage, thoracic aorta, atrial septum, and mitral valvular apparatus can be obtained readily.  We discuss historical and technical aspects of transesophageal echocardiography, anatomical views, and major clinical indications for this procedure.  These indications include intracardiac masses, thoracic aortic dissection, endocarditis, prosthetic and native cardiac valve function assessment, as well as its value in the detection of intracardiac source of systemic emboli.  Furthermore, the role of transesophageal echocardiography in the assessment of coronary artery and congenital heart disease and as an intraoperative diagnostic and monitoring technique is discussed.
