We developed the first biplane transesophageal echocardiography (TEE) probe with two orthogonal transducers, allowing synchronous side-by-side displays of heart on a monitor TV, and compared its diagnostic value that conventional single-plane TEE using commercially available Doppler equipment in 200 consecutive patients intraoperatively, perioperatively, or an outpatient basis.Insertion was easy, except one patient mediastinal tumor, no complications were encountered. Both transverse longitudinal scans allowed correct identification true false lumina all 30 aortic dissection examinations, but scanning slightly superior detecting types I III entry sites. Three entries not detected by (two DeBakey type III) visualized scanning. Among 37 cases mitral regurgitation (MR), significantly (p less than 0.05) revealing multiple jets (nine scanning). Although both planes yielded almost identical mean values for maximum jet areas, difference over 50% area size observed 19 cases. The measured areas showed significant correlation angiographic MR grading, especially larger measurements 0.01), different grades little overlap. Longitudinal images increased acoustic window aorta from esophagus. Moreover, provided good visualization ventricular outflow tracts, ascending aorta, main pulmonary artery, vena cava.This modality greatly facilitates three-dimensional comprehension cardiovascular lesions flow dynamics, MR, safety demonstrated. Our data demonstrate usefulness this new technique comparison TEE.
