为了确定非侵入性方法检测主动脉瓣关闭不全的相对敏感性和特异性，我们比较了听诊、超声心动图和脉冲多普勒超声心动图检测106例主动脉瓣关闭不全患者的准确性，这些患者通过瓣上动脉造影显示病变的存在或不存在。脉冲多普勒超声心动图诊断主动脉瓣返流的敏感性和特异性分别为96%和96%，听诊为73%和92%，二维超声心动图为43%和91%，二尖瓣前叶扑动为46%和81%，室间隔扑动为9%和96%。在主动脉瓣关闭不全的诊断中，听诊比M型或二维超声心动图更敏感（p <0.01）。脉冲多普勒超声心动图的敏感性明显高于听诊（p <0.0001），19例无杂音的患者为阳性，因此脉冲多普勒超声心动图是主动脉瓣关闭不全的最佳无创性标记。
To determine the relative sensitivity and specificity of noninvasive methods for detecting aortic insufficiency, we compared the accuracy of auscultation, echocardiography, and pulsed Doppler echocardiography in detecting aortic insufficiency in 106 patients in whom the presence or absence of the lesion was shown by supravalvular aortography. The sensitivity and specificity for the diagnosis of aortic regurgitation was 96% and 96% for pulsed Doppler echocardiography, 73% and 92% for auscultation, 43% and 91% for two-dimensional echocardiography, 46% and 81% for anterior mitral leaflet flutter, and 9% and 96% for ventricular septal flutter, respectively. Auscultation was more sensitive than either M-mode or two-dimensional echocardiography in the diagnosis of aortic insufficiency (p less than 0.01). Pulsed Doppler echocardiography was significantly more sensitive than auscultation (p less than 0.0001) and was positive in 19 patients in whom no murmur was found. Thus, pulsed Doppler echocardiography is the optimal noninvasive marker for aortic insufficiency.
