Congestive hepatopathy is a type of medical liver disease caused by right heart failure.

General

  • Liver failure due to (right) heart failure.
  • AKA cardiac cirrhosis - a term used by clinicians.
    • Generally, it does not satisfy pathologic criteria for cirrhosis.[1]

Gross

  • "Nutmeg" liver - yellow spotted appearance.

Microscopic

Features:[2]

  • Zone III atrophy.
  • Portal venule (central vein) distension.
  • Perisinusoidal fibrosis - progresses to centrilobular fibrosis and then diffuse fibrosis.
  • Dilation of sinusoids in all zone III areas - key feature.[3]

DDx:

Cardiac (congestive) hepatopathy, wherein outflow obstruction occurs secondary to backflow from a failing heart, and Budd Chiari syndrome, wherein obstruction of outflow occurs secondary to obstruction, usually thrombotic, have overlapping features, including sinusoidal dilation with emphasis upon the central vein, space of Disse erythrocytes, centrilobular inflammation, hemorrhage, bile ductules, and hemosiderin, and portal inflammation, fibrosis and bile ductular reaction. Centrilobular dropout/necrosis is more common in Budd Chiari syndrome, while peri-central venous and sinusoidal fibrosis are more common in cardiac hepatopathy. In end stage liver, fibrosis for cardiac hepatopathy comprises stellate centrizonal fibrous with haphazard spread, as opposed to the more frequent nodular cirrhosis in Budd-Chiari. Clinical findings are important to take into account, as cardiac failure is usually well known at the time of diagnosis as are the clinical predictors of Budd Chiari syndrome, prothrombotic states, myeloproliferative diseases, and oral contraceptive use.
