“…20,21,32 From these reports, in this study, we divided the HV waveforms into 3 categories according to the position of the V wave above or below the baseline as a new classification. Similar to previous reports regarding renal congestion, [24][25][26] Doppler HV waveforms in this study were found to be associated with CVP. However, measurement of HV waveforms seemed to be superior to those of intrarenal venous flow pattern, in terms of ease of measurement and accuracy of CVP, because of their closer anatomic proximity to the heart.…”

“…[20][21][22][23] With regard to intrarenal venous congestion, it has recently been reported that Doppler intrarenal venous flow pattern is simply classified by the presence or absence of systolic and diastolic interruption and reflects CVP. [24][25][26] These interruptions were associated with an elevated A wave and an elevated V wave in intrarenal venous waveforms, and the elevated V wave was caused by increased CVP and right ventricular dysfunction.…”

Background: It has been reported that the pattern of hepatic vein (HV) waveforms determined by abdominal ultrasonography is useful for the diagnosis of hepatic fibrosis in patients with chronic liver disease. We aim to clarify the clinical implications of HV waveform patterns in patients with heart failure (HF). Methods: We measured HV waveforms in 350 HF patients, who were then classified into 3 categories based on their waveforms: those with a continuous pattern (C group); those whose V wave ran under the R ESUM E

“…In the present study, prevalence of monophasic IRVF pattern was 10.6%, and was lower than 22.5% of previous study 17 . Although we could not fully explain the difference of their IRVF patterns, above changes in IRVF patterns 25 depending on renal congestion might affect their differences. Increased renal interstitial pressure reduces hydrostatic and colloid osmotic pressure differences between glomerular capillaries and Bowman's space 26 .…”

“…The increased CVP causes the increase of renal interstitial pressure and intrarenal parenchymal compliance around the intrarenal vessels, fibrosis, and leads the resistance of IRVF 17,23,24 . It has been reported that 22.5% of HF patients showed monophasic IRVF pattern 17 , and that the IRVF patterns could be changed depending on the renal congestion, and their changes were associated with renal impairment and poor prognosis 25 . In the present study, prevalence of monophasic IRVF pattern was 10.6%, and was lower than 22.5% of previous study 17 .…”

We aimed to clarify clinical implications of intrarenal hemodynamics assessed by intrarenal Doppler ultrasonography (IRD) and their prognostic impacts in heart failure (HF). We performed a prospective observational study, and examined IRD and measured interlobar renal artery velocity time integral (VTI) and intrarenal venous flow (IRVF) patterns (monophasic or non-monophasic pattern) to assess intrarenal hypoperfusion and congestion in HF patients (n = 341). Seven patients were excluded in VTI analysis due to unclear imaging. The patients were divided into groups based on (A) VTI: high VTI (VTI ≥ 14.0 cm, n = 231) or low VTI (VTI < 14.0 cm, n = 103); and (B) IRVF patterns: monophasic (n = 36) or non-monophasic (n = 305). We compared post-discharge cardiac event rate between the groups, and right-heart catheterization was performed in 166 patients. Cardiac index was lower in low VTI than in high VTI (P = 0.04), and right atrial pressure was higher in monophasic than in non-monophasic (P = 0.03). In the Kaplan–Meier analysis, cardiac event rate was higher in low VTI and monophasic groups (P < 0.01, respectively). In the Cox proportional hazard analysis, the combination of low VTI and a monophasic IRVF pattern was a predictor of cardiac events (P < 0.01). IRD imaging might be associated with cardiac output and right atrial pressure, and prognosis.

“…al have also shown that the changes in IRD pattern at follow up are prognostically important, and that a persistently discontinuous pattern is associated with deteriorating renal function. 24 Beaubien-Souligny demonstrated that abnormal IRD and portal venous Doppler flow patterns predicted AKI among post cardiac surgery patients. 25 These authors also developed a multiparameter point-of-care venous excess ultrasound score (VEXUS) for grading systemic venous congestion severity.…”
