Sensitivity and specificity of detection of mitral regurgitation was assessed by range-gated Doppler echocardiography. The degree of mitral regurgitation was also estimated by the depth and width of the regurgitant jet detected with Doppler and compared with that assessed by left ventriculography. Of 47 patients with an adequate Doppler study, 24 had no mitral regurgitation by ventriculography. All but one were also negative for mitral regurgitation by Doppler, for a specificity of 96%. Of 23 cases with mitral regurgitation documented by ventriculography, Doppler detected mitral regurgitation in 21, for a sensitivity of 92%. Two cases with mitral regurgitation undiagnosed by Doppler had mild mitral regurgitation due to papillary muscle dysfunction. All cases with rheumatic mitral regurgitation were detected. The degree of mitral regurgitation estimated with Doppler had a high correlation with that determined by ventriculography (r = 0.88, p less than 0.01).
通过距离选通多普勒超声心动图评估二尖瓣反流检测的敏感性和特异性。二尖瓣反流的程度也通过多普勒检测到的反流束的深度和宽度进行估计，并与左心室造影评估的结果进行比较。在47例进行了充分多普勒研究的患者中，24例经心室造影显示无二尖瓣反流。除1例之外，其余所有患者经多普勒检查二尖瓣反流也为阴性，特异性为96%。在23例经心室造影证实有二尖瓣反流的病例中，多普勒检测到二尖瓣反流的有21例，敏感性为92%。2例经多普勒未诊断出二尖瓣反流的病例是由于乳头肌功能障碍导致的轻度二尖瓣反流。所有风湿性二尖瓣反流病例均被检测到。用多普勒估计的二尖瓣反流程度与心室造影确定的程度高度相关（r = 0.88，p < 0.01）。
