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.
本研究的目的是比较多平面经食管超声心动图（TEE）与更传统的双平面技术在直接评估主动脉瓣狭窄患者主动脉瓣面积时的准确性。在接受多平面TEE检查的所有81例患者中均获得了足以测量主动脉瓣面积的主动脉瓣短轴图像，但在采用双平面方法检查的64例患者中，只有56例（88%）获得了此类图像。多平面TEE测定的主动脉瓣面积的相关系数（r = 0.89；标准估计误差[SEE] = 0.04 cm²）高于双平面TEE（r = 0.74；SEE = 0.06 cm²）（p < 0.01）。双叶瓣的相关性（多平面，r = 0.93；双平面，r = 0.75）高于三叶瓣（多平面，r = 0.87；双平面，r = 0.75）。我们的研究已证明，在直接评估主动脉瓣狭窄患者的主动脉瓣面积方面，多平面TEE优于双平面TEE和经胸超声心动图（TTE）。
