Non-invasive quantification of mitral regurgitation remains a clinical problem. The aim of this study was to assess a new methodology of Doppler echocardiographic assessment of the mitral regurgitant fraction. The study included 60 patients (average age 61 years) in sinus rhythm with mitral regurgitation. The cardiac output was measured by Doppler echocardiography at four sites: the aortic, pulmonary and mitral rings and at the tips of the mitral leaflets by a method previously validated and published. Using the average of the aortic and pulmonary cardiac outputs on the hand and the mitral cardiac output on the other, it was possible to calculate the regurgitant fraction: (mean mitral flow-mean aortic/pulmonary flow)/mean mitral flow. This was correlated with the Sellers angiographic grades of regurgitation. The results confirm this validated procedure: the correlation of aortic and pulmonary flows was good: r = 0.94. This also held true for mitral flow at the two sites: r = 0.96. The correlation between the Doppler echocardiographic regurgitant fraction and the angiographic estimation of the severity of mitral regurgitation was good: r = 0.89. There was a statistically significant difference between the Doppler echocardiographic regurgitant fractions corresponding to Sellers Grades I, II and III mitral regurgitation (p = 0.0001). This study shows that Doppler echocardiographic measurements of blood flow at different orifices of the heart applied to the quantification of mitral regurgitation is a reliable method, the use of which, with strict methodological criteria, may be proposed in everyday clinical practice.
