Implication

Supports non-invasive RV assessment in HF; leaves open outcome impact pending prospective validation.

Key Points

Determine whether tricuspid annular motion parameters derived from pulsed Doppler tissue imaging reliably assess right ventricular systolic function in heart failure patients.
Acquired standard and pulsed Doppler tissue echocardiography measurements of tricuspid annular velocities in 44 heart failure patients (mean left ventricular ejection fraction 24 ± 7%) and 30 age- and sex-matched healthy controls.
Performed first-pass radionuclide ventriculography to measure right ventricular ejection fraction and equilibrium gated SPECT within 2 hours of Doppler imaging.
Peak systolic annular velocity was significantly lower (10.3 ± 2.6 cm/s vs 15.5 ± 2.6 cm/s, P < 0.001) and time to peak velocity was longer (198 ± 34 ms vs 171 ± 29 ms, P < 0.01) in heart failure patients compared to controls.
Systolic annular velocity correlated with right ventricular ejection fraction (r = 0.648, P < 0.001), where a velocity < 11.5 cm/s detected right ventricular dysfunction (ejection fraction < 45%) with 90% sensitivity and 85% specificity.

Doppler tissue imaging of tricuspid annular motion vs. Healthy subjects was evaluated on Peak systolic annular velocity (cm/s) (p=<0.001).
