Abstract

Right atrial pressure (RAP) reflects volume and pressure hemodynamics of right cardiac chambers. Previous attempts for noninvasive assessment of RAP include 2-dimensional and Doppler correlates of RAP, which require the presence of optimal subcostal views that may not be always feasible. In this study we utilized Doppler tissue imaging of the tricuspid annulus in the apical 4-chamber view, for noninvasive assessment of RAP. An inverse relationship was demonstrated between mean RAP and the interval between the end of the systolic annular motion to the onset of the early diastolic filling wave (right ventricular regional isovolumic relaxation time).
