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. Q1997 by Excerpta Medica, Inc.
