The time interval between the onset of tricuspid E wave and annular Ea wave (TE-Ea) can predict right atrial pressure in patients with heart failure

Abstract

Objective: There is conflicting data regarding the tricuspid annular velocities and their relation to right ventricular filling pressures. We aimed to assess if the time interval between the onset of tricuspid E wave and annular Ea wave has any correlation with right sided filling pressure in patients with heart failure.Methods: Thirty heart failure patients (left ventricular ejection fraction0.05) but the correlation between TE-Ea and RAP was significant (r=0.5, p=0.01).Conclusion: According to our results and in contrary to some prior studies, we showed for the first time that right side Tsurrogate of right atrial pressure than E/Ea in heart failure patients. This finding needs more accurate studies and could present Tfeasible tool to look into hemodynamics of heart failure patients.
