Our experience with pulsed-Doppler echocardiography in mitral and aortic valve insufficiency is reported. The data resulting from the echo-Doppler analysis were compared to those found in angiocardiography. Left ventriculography was positive for mitral insufficiency in 19 patients and negative in 17 patients. Aortography was positive for aortic insufficiency in 22 patients and negative in 15 patients. The echo-Doppler analysis showed a specificity of 94% and a sensitivity of 86% for mitral valve insufficiency. A specificity of 83% and a sensitivity of 91% was found for aortic valve insufficiency in supersternal notch view. The location of the sample volume and the morphology of the flow profile for each individual valvulopathy are described which proved considerably useful in current diagnostic practice. The possible causes of false positives and negative are discussed. In our series, the data obtained through echo-Doppler analysis were found to be only quantitative and it was not possible to quantity the regurgitation.
本文报告了我们应用脉冲多普勒超声心动图诊断二尖瓣和主动脉瓣关闭不全的经验。将超声多普勒分析所得数据与心血管造影结果进行了比较。左心室造影显示，19例患者二尖瓣关闭不全呈阳性，17例呈阴性。主动脉造影显示，22例患者主动脉瓣关闭不全呈阳性，15例呈阴性。超声多普勒分析显示，二尖瓣关闭不全的特异性为94%，敏感性为86%。在胸骨上切迹视图中，主动脉瓣关闭不全的特异性为83%，敏感性为91%。描述了每种瓣膜病样本容积的位置和血流剖面形态，这在当前诊断实践中被证明非常有用。讨论了假阳性和假阴性的可能原因。在我们的系列研究中，发现通过超声多普勒分析获得的数据仅为定量数据，无法对反流进行定量。
