Congestive hepatopathy is a complication of right heart failure and chronically elevated right heart pressure. Histologic findings include sinusoidal dilatation, centrilobular hepatocellular plate atrophy, and fibrosis. We performed a validation study of a recently proposed scoring system (0 to 4 scale) for congestive hepatic fibrosis on 38 liver biopsies. Glutamine synthetase immunohistochemistry was also performed, and loss of centrizonal immunoreactivity correlated with increasing fibrosis score (P<0.01). Interobserver concordance for congestive hepatic fibrosis score based on Masson trichrome stain was initially fair (Fleiss κ=0.28, weighted concordance coefficient=0.60) and significantly improved (κ=0.40, weighted concordance coefficient=0.66) following a multiheaded microscope training session and inclusion of glutamine synthetase immunohistochemistry. Average congestive hepatic fibrosis score correlated with significantly higher right atrial pressure, severity of right atrial dilation, presence of right ventricular dilation, elevated serum alanine aminotransferase, platelet counts, prothrombin time, and model for end-stage liver disease score. In conclusion, the congestive hepatic fibrosis scoring system is reproducible among pathologists and correlates with clinical and laboratory markers of congestive hepatopathy.
