Clinical impact of portal vein pulsatility on the prognosis of hospitalized patients with acute heart failure

Figure 1 Portal vein flow in the control and heart failure groups. A and B: Representative portal vein (PV) flow waveform in the control (A) and heart failure (HF) (B) groups at admission. Patients with HF had a pulsatile PV flow waveform. Patients in the control group had a continuous PV flow waveform with a significantly higher minimum PV velocity; C: Representative PV flow waveform in a patient with HF at discharge. At discharge, the waveform turned into a continuous pattern. HF: Heart failure; PVPR: Portal vein pulsatility ratio.
