Key result
Portal vein pulsatility score ≥3 identifies elevated right atrial pressure with 100% specificity.
Why the study?
A better understanding of portal vein pulsatility in congestive heart failure was needed.
Does portal vein pulsatility measured by duplex Doppler correlate with right atrial pressure in patients suspected of congestive heart failure?
Observational (n=34)
Does portal vein pulsatility measured by duplex Doppler correlate with right atrial pressure in patients suspected of congestive heart failure?
Absolute Event Rate: 60% vs 0%
Portal vein pulsatility on duplex Doppler is a specific sign of elevated systemic venous pressure in patients with suspected congestive heart failure.

May support portal vein pulsatility as a specific noninvasive marker of elevated right atrial pressure; leaves open need for prospective validation before clinical use.
Duerinckx et al. (1990) conducted an observational in Congestive heart failure (n=34). Right atrial pressure ≥10 mm Hg vs. Right atrial pressure <10 mm Hg and healthy volunteers was evaluated on Portal vein pulsatility score ≥3. A portal vein pulsatility score of 3 or greater identified patients with elevated right atrial pressure (≥10 mm Hg) with 60% sensitivity and 100% specificity.
