Why the study?
Does assessment of right ventricular isovolumic relaxation time using tissue Doppler imaging predict cardiac death and non-fatal cardiac events in patients with symptomatic chronic heart failure?
Does assessment of right ventricular isovolumic relaxation time using tissue Doppler imaging predict cardiac death and non-fatal cardiac events in patients with symptomatic chronic heart failure?
RV IVRT measured by tissue Doppler imaging is not a strong independent predictor of adverse outcomes in chronic heart failure compared to invasive hemodynamics, serving only as an auxiliary risk stratification tool.
RV IVRT by TDI was not independently predictive in chronic HF; leaves open whether noninvasive RV parameters add value beyond invasive hemodynamics.
