Abstract

Color Doppler echocardiographic examination was performed to detect and evaluate semiquantitatively the severity of mitral regurgitation in 38 patients who underwent left ventriculography. The sensitivity and specificity of the technique in the detection of mitral regurgitation was 84% and 100% as compared with left ventriculography.Mitral regurgitation in the false negative cases was mostly mild. On the bases of the farthest distance reached by the regurgitation flow signal from the mitral value orifice, the severity of regurgitation was graded on a four point scale and these results were compared with those of angiography. A significant correlation(r=0.87) was found between Doppler imaging and angiography in the evaluation of the severity of mitral regurgitation.Also results was obtained for the evaluation based on the area covered by the regurgitant signals in the left atrial cavity & the regurgitant jet area(RJA) experssed as a percentage of the left atrial are(LLA) obtained in the same plane(RJA/LLA%). In conclusion, Color Doppler echocardiography is a useful noninvasvive thechique that is not only sensitive and specific in the identification of mitral regurgitation but also provides accurate estimation og its severity.
