Color Doppler tissue imaging for evaluation of right ventricular systolic function in patients with congenital heart disease.
OBJECTIVE
We sought to explore the relationship of color Doppler tissue imaging-derived systolic indices of tricuspid valve annular motion and magnetic resonance imaging-derived right ventricular (RV) ejection fraction in patients with congenital heart disease.


METHODS
Patients with congenital heart disease who underwent echocardiography and magnetic resonance imaging on the same day were included. The tricuspid valve annular color Doppler tissue imaging-derived parameters of peak velocity during isovolumic contraction, myocardial acceleration during isovolumic contraction, peak systolic velocity, and Tei index were compared with magnetic resonance imaging-derived RV ejection fraction.


RESULTS
Peak systolic velocity and myocardial acceleration during isovolumic contraction correlated well with RV ejection fraction after adjusting for age, RV dilation, and pressure overload (r = 0.65 and 0.73, respectively). Interobserver and intraobserver reliability were excellent for peak systolic velocity (r = 0.95 and 0.97, respectively) and very good for myocardial acceleration during isovolumic contraction (r = 0.93 and 0.85, respectively).


CONCLUSIONS
Color Doppler tissue imaging indices of tricuspid valve annular motion are reproducible and provide a potentially useful complementary tool for assessment of RV systolic function in patients with congenital heart disease.
