Abstract
The aim of the study was to compare the accuracy of multiplane transesophageal echocardiography (TEE) with the more conventional biplane technique in the direct assessment of aortic valve area in patients with aortic stenosis. Short-axis images of the aortic valve adequate for measuring aortic valve area were obtained in all 81 patients studied by multiplane TEE but in only 56 of 64 patients (88%) using the biplane approach. The correlation coefficient for aortic valve area determined by multiplane TEE (r  0.89; SEE  0.04 cm2) was higher (p ›0.01) than biplane TEE (r  0.74; SEE  0.06 cm2). Correlations were higher for bicuspid valves (multiplane, r  0.93; biplane, r  0.75) than tricuspid valves (multiplane, r  0.87; biplane, r  0.75). Our study has demonstrated the superiority of multiplane TEE to both biplane TEE and transthoracic echocardiography (TTE) in the direct evaluation of aortic valve area in patients with aortic stenosis.
