The pulsatile pattern of the portal vein is considered a marker of right ventricular dysfunction, but volemia may also contribute to this phenomenon. The separate influence of each factor remains debated, as the interplay between right ventricular dysfunction and volume status is complex. Additionally, right ventricular dysfunction can originate from either diastolic or systolic dysfunction, further complicating the understanding of their distinct impacts on portal vein pulsatility.
