Key result
Peak tricuspid annulus systolic velocity by Doppler tissue imaging showed excellent correlation with RVFAC (r=0.84, P<0.001) and TAPSE (r=0.90, P<0.001) for assessing right ventricular function.
Why the study?
Does peak tricuspid annulus systolic (TA Sa) velocity derived from Doppler tissue imaging correlate with RVFAC and TAPSE in estimating RV function in patients with varying degrees of pulmonary hypertension?
Observational (n=52)
Does peak tricuspid annulus systolic (TA Sa) velocity derived from Doppler tissue imaging correlate with RVFAC and TAPSE in estimating RV function in patients with varying degrees of pulmonary hypertension?
Effect estimate: r = 0.84 (vs RVFAC) and r = 0.90 (vs TAPSE)
p-value: p=<0.001
Peak tricuspid annulus systolic velocity by Doppler tissue imaging is a reliable and easily obtainable alternative to RVFAC and TAPSE for assessing right ventricular systolic function in patients with pulmonary hypertension.

Supports TA Sa velocity as RV function marker in pulmonary hypertension; leaves open prospective outcome validation.
Saxena et al. (2006) conducted an observational in Pulmonary hypertension (n=52). Peak tricuspid annulus systolic (TA Sa) velocity by Doppler tissue imaging vs. RV fractional area change (RVFAC) and tricuspid valve annular motion (TAPSE) was evaluated on Correlation between peak TA Sa velocity and RVFAC/TAPSE to estimate RV function (r = 0.84 (vs RVFAC) and r = 0.90 (vs TAPSE), p=<0.001). Peak tricuspid annulus systolic velocity by Doppler tissue imaging showed excellent correlation with RVFAC (r=0.84, P<0.001) and TAPSE (r=0.90, P<0.001) for assessing right ventricular function.
