Assessment of tricuspid regurgitation by Doppler color flow imaging: angiographic correlation

Int J Cardiol. 1994 May;44(3):275-83. doi: 10.1016/0167-5273(94)90292-5.


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. Fifty-four patients with rheumatic heart disease who underwent right ventriculography and transthoracic Doppler color flow imaging were studied. The regurgitant jet area was measured as the largest clearly definable flow disturbance in apical four-chamber and right ventricle inflow views, and expressed in both views as the absolute jet area or as the ratio of maximal jet area to right atrial area. Correlation of all Doppler color flow measurements with angiographic grades of TR were comparable, absolute jet area in apical four-chamber view being closest at r = 0.80. A regurgitant jet area in apical four-chamber view < 5 cm2 predicted minimal or mild TR by angiography with a sensitivity of 78% and a specificity of 100%, whereas a regurgitant jet area > 10 cm2 predicted severe TR with a sensitivity of 92% and a specificity of 91%. 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)
