Chronic passive congestion, liver
Click picture to enlarge. Close window to return
Passive congestion of the liver occurs when there is right heart failure. The failure of the right ventricle causes the systemic circulation to back up behind it. In the liver, this manifests as centrolobular congestion, centered on the central vein. If the condition persists long enough, there may actually be necrosis of hepatocytes near the central vein. The repair process ensues, with resulting central fibrosis, or so-called "cardiac cirrhosis". The pattern of fibrosis is different from cirrhosis due to alcoholic liver disease, since fibrosis in that condition bridges from portal to portal.
