Ischemic hepatitis is an uncommon cardiovascular surgery complication. Hepatic biopsies show centrolobulillar necrosis. The term "hepatitis" was proposed because of a raise in hepatic enzymes similar with infectious disease, and "ischemic" because of failure in hepatic perfusion. Ischemic hepatitis was then defined as an acute and reversible elevation of hepatic enzymes (within 72 h), associated with disturbance in hepatic perfusion after excluding other causes of acute hepatitis. A 53 year-old male presented complaining of a 12 h epigastric pain, without nausea or vomiting, resistant to medication. He underwent an aortic valve replacement and was under anticoagulation. He suddenly developed shock and multiorgan failure. Jaundice and cardiac tamponade signs were present, associated with elevated hepatic enzymes. A transthoracic echocardiography accounted for cardiac tamponade signs. A pericardiocentesis was performed, removing 970 cc of hemorrhagic fluid, and hemodialysis, with improvement of his hemodynamic status. Hepatic enzymes improved. Viral markers were negative.
