Sixty-five patients were studied for the presence of aortic insufficiency by auscultation, conventional M mode echocardiography (echo), range-gated pulse Doppler flowmeter (Doppler), and supravalvular aortic angiography. Aortic insufficiency was demonstrated angiographically in 49 patients, of which eight (16%) were missed by auscultation. Echo missed 20 (41%), and Doppler missed seven (14%). Only two (4%) were missed by auscultation and Doppler combined. All methods were highly specific, but the combination of auscultation and Doppler was the most sensitive noninvasive method for detecting aortic insufficiency.
对65例患者通过听诊、传统M型超声心动图（超声）、距离选通脉冲多普勒流量计（多普勒）和主动脉瓣上血管造影术研究主动脉瓣关闭不全的情况。血管造影显示49例患者存在主动脉瓣关闭不全，其中8例（16%）通过听诊漏诊。超声漏诊20例（41%），多普勒漏诊7例（14%）。听诊和多普勒联合检查仅漏诊2例（4%）。所有方法特异性均很高，但听诊和多普勒联合是检测主动脉瓣关闭不全最敏感的非侵入性方法。
