Does live 3D TTE measurement of vena contracta area correlate with standard 2D TTE measurements for the quantification of tricuspid regurgitation?
Live 3D TTE color Doppler measurements of vena contracta area can be used for quantitative assessment of tricuspid regurgitation, offering incremental value particularly for severe lesions.
We evaluated tricuspid regurgitation (TR) by multiple echocardiographic techniques in 93 consecutive patients who underwent standard two-dimensional (2D) and live three-dimensional (3D) transthoracic echocardiography (TTE). TR vena contracta (VC) area was obtained by 3D TTE by systematic and sequential cropping of the acquired 3D TTE dataset. Assessment of VC area by 3D TTE was compared to 2D TTE measurements of the ratio of TR regurgitant jet area to right atrial area (RJA/RAA), RJA alone, VC width, and calculated VC area. VC area from 3D TTE closely correlated with RJA/RAA and RJA alone as determined from 2D TTE measurements. Live 3D TTE color Doppler measurements of VC area can be used for quantitative assessment of TR and offer incremental value for quantification of particularly severe regurgitant lesions.
Velayudhan et al. (2006) conducted an observational in Tricuspid regurgitation (n=93). Live 3D transthoracic echocardiography (TTE) vena contracta area measurement vs. 2D TTE measurements was evaluated on Correlation between 3D TTE vena contracta area and 2D TTE measurements. Live 3D TTE measurement of vena contracta area closely correlated with 2D TTE measurements, offering incremental value for quantifying severe tricuspid regurgitation.
