The portal vein (which is rich in nutrients and relatively high in oxygen) provides two thirds of blood flow to the liver. The hepatic artery (which is oxygen-rich)... read more .)
Moderate or severe right-sided heart failure increases central venous pressure, which is transmitted to the liver via the inferior vena cava and hepatic veins. Chronic congestion leads to atrophy of hepatocytes, distention of sinusoids, and centrizonal fibrosis, which, if severe, progresses to cirrhosis (cardiac cirrhosis). The basis for liver cell death is probably sinusoidal thrombosis that propagates to the central veins and branches of the portal vein, causing ischemia.
Symptoms and Signs of Congestive Hepatopathy
Most patients are asymptomatic. However, moderate congestion causes right upper quadrant discomfort (due to stretching of the liver capsule) and tender hepatomegaly. Severe congestion leads to massive hepatomegaly and jaundice Jaundice Jaundice is a yellowish discoloration of the skin and mucous membranes caused by hyperbilirubinemia.

Diagnosis of Congestive Hepatopathy
Clinical evaluation
Congestive hepatopathy is suspected in patients who have right-sided heart failure, jaundice, and tender hepatomegaly. Laboratory test results are modestly abnormal: unconjugated hyperbilirubinemia (total bilirubin < 3 mg/dL [51.31 micromol/L]), elevated (usually < 2- to 3-fold) aminotransferases, and prolonged prothrombin time/international normalized ratio (PT/INR). Ascitic fluid, if present, is characterized by a high serum-to-ascites albumin concentration gradient (the serum albumin concentration minus the ascitic albumin concentration [SAAG]). Gradients ≥ 1.1 g/dL (11 g/L) are relatively specific for ascites Ascites Ascites is free fluid in the peritoneal cavity. The most common cause is portal hypertension.

Because the laboratory abnormalities are nonspecific, recognition of congestive hepatopathy is ultimately clinical. The liver disorder is more important as an index of the severity of heart failure than as a diagnosis by itself.
