In heart failure, when the heart can longer pump blood forward effectively, the blood tends to stagnate and dams backwards congesting organs such as the liver - congestive hepatopathy. The sites in the liver surrounding veins containing this stagnant dammed blood appear red-brown while the other areas of normal liver look yellow. When seen with the naked eye, this speckling of red-brown against a yellow background gives the liver an appearance similar to that of a grated nutmeg – nutmeg liver.
