In the study, 139 valvular regurgitations of 120 patients (55 mitral and 84 aortic regurgitations) were investigated and compared by means of colour flow mapping and heart catheterization. During the echocardiographic examination, the length and width of the regurgitant jets were measured and the jet area was planimetered besides the subjective grades. The above parameters were correlated with the angiographic grades. Good agreement was found between the results of the two methods. As concerns the different parameters of the regurgitant jets in mitral regurgitation, the most severe (grade IV) category was easily distinguished from the others, while in aortic regurgitation all four categories were differentiated by colour flow mapping. These measurements indicated that colour-coded Doppler echocardiography is a suitable tool for detection of the severity of valvular regurgitations in a noninvasive way.
