Abstract

|
|
Color Dopper ec locardiographic examination was performed to detect and evaluate semiquantitatively the severity of tricuspid regurgitation in 40 patients who underwent right ventriculography, and the results obained by 2 methods were compared.
The sensitivity and specificity of the color Dopple rechocardiographic examination in the detection of tricuspid regurgitation was 94% and 100% respectively, as compared with right ventriculography. False negative cases by echocardiography were only in 2 cases and the degree of regurgitation was mild by angiogrphy.
On the bases of the maximal distance by the regurgitant flow from the tricuspid orifice, the severity of regurgitation was graded on a four point scale and these results were compared with those of right ventriculography.
There was a significant correlation(r=0.701) between Doppler imaging and angiography in the evaluation of the severity of tricuspid regurgitation. Also results were obtained for the evaluation based on the area covered by the regurgitant flow in the right atrial cavity(r=0.562), and the ratio of maximum regurgitant jet area to right atrial area(r=0.704).
In conclusion, color Doppler echocardiography is a useful non-invasive technique that is not sensitive and specific in the
detection of tricuspid regurgitation, but also provides reliable estimation of its severity.
