The correlation between data obtained by Doppler color flow imaging and angiographic severity has been investigated in mitral and aortic regurgitation. However, similar studies have not been performed for tricuspid regurgitation (TR). This study was performed to establish the correlation between measurements of regurgitant jet area by Doppler color flow imaging and the angiographic severity of TR. ⋯ Values between 5 and 10 cm2 predicted moderate TR with a sensitivity of 89% and a specificity of 89%. Sensitivity and specificity were not improved with use of the ratio of jet area to right atrial area or with use of right ventricle inflow view. Thus, Doppler color flow jet measurements correlate closely with angiographic results in the evaluation of TR.(ABSTRACT TRUNCATED AT 250 WORDS)
