Aim of the study: In chronic heart failure (CHF) patients, renal congestion plays a key role in
determining the progression of renal dysfunction and a worse prognosis. The aim of this …

Background It remains unclear whether intrarenal venous flow (IRVF) patterns in patients
with heart failure (HF) could change over the clinical course, and whether the changes could …

Background It has been recently reported that the renal venous stasis index (RVSI)
assessed by renal Doppler ultrasonography provides information to stratify pulmonary …

Background The impact of changes in Doppler‐derived kidney venous flow in heart failure
(HF) is not well studied. We aimed to investigate the association of Doppler‐derived kidney …

Background Discontinuous intrarenal venous flow patterns, as assessed by renal Doppler
ultrasound examination, are associated with changes in hemodynamics such as volume …

Background Persistent congestion with deteriorating renal function is an important cause of
adverse outcomes in heart failure. We aimed to characterize new approaches to evaluate …

Objectives: This study clarified the characteristics of intrarenal Doppler ultrasonography
(IRD) profiles and their prognostic implications in heart failure (HF). Background: IRD can …

Worsening renal function (WRF) during the treatment of acute decompensated heart failure
(ADHF) occurs in up to a third of patients and is associated with worse survival. Venous …

Background: Interruption in Doppler intrarenal venous flow (IRVF) has been used in
assessing renal congestion and in the prediction of prognosis of cardiovascular diseases …

The development of venous congestion in patients with heart failure (HF) is established as
one of the main pathophysiological determinants of morbidity and mortality. 1, 2 Recently …
