Systemic lupus erythematosus (SLE) is one of the most common autoimmune diseases and patients suffering from this disease often died of massive hemorrhage. We report the case of a patient who died of acute massive hemorrhage three weeks after mitral valve replacement. The patient, a 42 year-old woman, had been diagnosed as having valvular heart disease at the age of 10. She underwent mitral commissurotomy at the ages of 18 and 32. SLE was diagnosed 8 years previously and corticosteroid therapy was initiated. The patient was experiencing exertional dyspnea again 1 year ago and mitral valve replacement was performed for recurrent stenosis. The postoperative course seemed to be uneventful, but on the 21st postoperative day, acute massive mediastinal hemorrhage occurred, and the patient eventually died of septicemia. Massive hemorrhage in SLE patients usually occur in the central nervous system or alimentary tract. However, bleeding can occur anywhere, so great care must be taken in regulating anticoagulant therapy.
