Color Doppler and two-dimensional echocardiographic determination of the mechanism of aortic regurgitation with surgical correlation.
The character of the color flow Doppler jet provides information on the mechanism and pathologic elements of valve dysfunction. This has been useful in the evaluation of mitral regurgitation, a repairable problem, but has not been described comprehensively for the aortic valve. The purpose of our study was to correlate the color flow Doppler characteristics of the aortic regurgitant jet and two-dimensional echocardiographic findings of valve mobility with surgical pathology. Prepump intraoperative echocardiography and color flow Doppler echocardiography were performed on 124 patients with aortic regurgitation and used to categorize leaflet motion as excessive, restricted, or normal, jet direction as eccentric or central, and jet origin between the cusps as eccentric, central, or diffuse. Bicuspid disease and tricuspid aortic valve prolapse were associated with excessive valve mobility and eccentric jet direction and origin. Conversely, annular dilation, rheumatic disease, sclerosis, and perforation were associated with normal or reduced cusp mobility and a central jet direction and origin (p = 0.001). Overall, an eccentric jet direction occurred in 69% of patients with excessive cusp mobility, whereas 71% of patients with normal or reduced cusp mobility had a central jet (p = 0.001). Therefore color flow Doppler determination of the eccentricity of regurgitant jet direction and origin is useful in predicting the mechanism and disease of aortic valve dysfunction. These observations may suggest the presence of prolapse and thus the potential for aortic valve repair.
