Doppler interrogation of blood flow in the hepatic veins (HVs) provides valuable information regarding a wide spectrum of pathological processes that affect the right heart. Systematic analysis of the direction, velocity, and phasicity of the HV waveforms allows one to distinguish normal from abnormal patterns and provides important diagnostic information. Abnormalities in heart rate, rhythm, and intracardiac conduction are commonly encountered during echocardiographic studies. Sinus bradycardia and tachycardia, bradyarrhythmias and tachyarrhythmias as well as atrioventricular conduction disturbances influence the flow pattern in the HVs and may pose a challenge to the correct interpretation of the HV Doppler. Alterations in HV flow that are induced by the electrical abnormalities may mimic right heart pathology. Awareness of these alterations allows one to avoid misinterpretation of the HV signal, helps diagnose the underlying rhythm or conduction abnormality, and permits assessment of the impact on right heart hemodynamics.

Background: Understanding venous congestion is critical to the management of many illnesses, but assessing volume status can be challenging. The current gold standard for volume status assessment of right heart catheterization (RHC) is invasive, costly, and often unavailable. Venous Excess Ultrasound Score (VExUS) is a novel ultrasound protocol for to assessment of venous congestion using the inferior vena cava, hepatic, portal and renal veins.

The contribution of the gut to the ingestion, production, absorption, and excretion of the extra ammonia and urea-N associated with feeding ("exogenous" fraction) has received limited prior attention. Analysis of commercial pellet food revealed appreciable concentrations of ammonia and urea-N. Long term satiation-feeding increased whole trout ammonia and urea-N excretion rates by 2.

Background: The incidence and mortality rate of hepatocellular carcinoma (HCC) are increasing globally. HCC with inferior vena cava tumor thrombus (HCCIVCTT) represents an advanced stage of the disease. Research suggests that for patients with advanced HCCIVCTT, liver resection combined with thrombectomy is a safe and feasible option that can provide moderate survival benefit.

Background: V617F-mutated myeloproliferative neoplasms (MPN) exhibit abnormal proliferation of bone marrow progenitors and increased risk of thrombosis, specifically in splanchnic veins (SVT). The contribution of the endothelium to the development of the prothrombotic phenotype was explored.
Material And Methods: Plasma and serum samples from V617F MPN patients with (n=26) or without (n=7) thrombotic debut and different treatments, were obtained (n=33).

Pregnant women with congenital heart disease carry a high risk of complications, especially when cardiac function is suboptimal. Increasing evidence suggests that impaired right ventricular (RV) function has a negative effect on placental function, possibly through venous congestion. We report a case series of hepatic and renal venous flow patterns in pregnant women with right ventricular dysfunction after repaired Tetralogy of Fallot (ToF), relative to those observed in normal pregnancy and preeclampsia.
