A, Anatomic specimen of heart and related structures, sectioned in basal short-axis plane. Note proximity of esophagus (E) to left atrium (LA), left atrial appendage (LAA), pulmonary veins, and descending thoracic aorta (Ao), posteriorly. B, Multiplane transesophageal echocardiogram (45° rotation) from a patient, showing basal structures similar to those in A. AS = atrial septum; B = bronchus; LUPV = left upper pulmonary vein; PV = pulmonary valve; RA = right atrium; R, L, and N = right, left, and noncoronary cusps of aortic valve; RVO = right ventricular outflow tract.

Graph showing utilization trends for transesophageal echocardiography (TEE) as a percentage of transthoracic echocardiography (TTE) at the Mayo Clinic. Note that percentage ranged from 5 to 6% during 1990 through TEE technology was introduced into our practice in 1988.

Top Panel, Evolution of transesophageal ultrasound transducer technology. A, Monoplane device is a single-plane transducer typically perpendicular to shaft of scope. B, In stacked biplane device, distal transverse plane is complemented by separate proximal longitudinal plane parallel to long axis of shaft of scope. C, In matrix biplane device, transverse and longitudinal plane arrays are interdigitated into single footprint. D, Multiplane device (OmniPlane, Hewlett-Packard Co.) uses single array that can be rotated 180°; thus, a continuum of orientations relative to shaft of scope can be produced.
(From Seward and associates.3) Bottom Panel, Photograph of array of commercially available transducers. Tips of transducers range from 7 to 12 mm, whereas shafts range from 5 to 9 mm. Typically, transducers are 60 to 110 cm long.
