Key result
Hepatic venous flow systolic filling fraction strongly correlated with mean right atrial pressure (r=0.88) and estimated mean RAP >8 mm Hg with 86% sensitivity and 92% specificity.
Why the study?
Can echocardiographic and Doppler parameters, specifically hepatic venous flow dynamics, accurately estimate mean right atrial pressure in patients undergoing invasive hemodynamic monitoring?
Cross-Sectional (n=85)
Can echocardiographic and Doppler parameters, specifically hepatic venous flow dynamics, accurately estimate mean right atrial pressure in patients undergoing invasive hemodynamic monitoring?
Effect estimate: r=0.88
Hepatic venous flow dynamics, particularly systolic filling fraction, provide a reliable non-invasive echocardiographic estimate of mean right atrial pressure.

May support noninvasive RAP estimation; hypothesis-generating and requires prospective validation before practice change.
Nagueh et al. (1996) conducted a cross-sectional in Patients requiring central venous or right heart catheterization (n=85). Echocardiographic and Doppler parameters vs. Invasive mean right atrial pressure was evaluated on Correlation between hepatic venous flow systolic filling fraction and mean right atrial pressure (r=0.88). Hepatic venous flow systolic filling fraction strongly correlated with mean right atrial pressure (r=0.88) and estimated mean RAP >8 mm Hg with 86% sensitivity and 92% specificity.
