Key result
Echocardiographic assessment of inferior vena cava wall motion yielded indices of emptying and collapsability that correlated well with right atrial mean pressure and right heart hemodynamics.
Why the study?
Does echocardiographic assessment of inferior vena cava wall motion correlate with right heart hemodynamics in patients with right-sided heart disease?
Observational (n=112)
Does echocardiographic assessment of inferior vena cava wall motion correlate with right heart hemodynamics in patients with right-sided heart disease?
Echocardiographic assessment of IVC wall motion provides useful indices, such as the collapsability index, that correlate with right atrial mean pressure and right heart hemodynamics.

May support noninvasive right atrial pressure estimation; leaves open prospective validation before clinical adoption.
Gullace et al. (1984) conducted an observational in Diseases involving the right side of the heart (n=112). Subcostal echocardiography of the inferior vena cava vs. Jugular pulse tracings / Normal subjects was evaluated on Variations of the IVC diameters in relation to right atrial mean pressure and time-relationship of IVC wall motion to cardiac events. Echocardiographic assessment of inferior vena cava wall motion yielded indices of emptying and collapsability that correlated well with right atrial mean pressure and right heart hemodynamics.
