Abstract

A few reports have suggested the beneficial effect of high-dose intravenous immunoglobulin (IVIG) in the treatment of acute myocarditis and cardiomyopathy. We describe a 49-year-old woman in which acute myocarditis was diagnosed on the basis of clinical and echocardiographic findings. Conventional treatment with captopril and frusemide was administered; intravenous heparin and, subsequently, oral anticoagulants were added because of the appearance of an apical thrombus. On the fifth day of hospitalization, treatment with high-dose (400 mg kg-1 day-1) IVIG was started and prosecuted for 5 days. A dramatic improvement of clinical conditions was observed, with increase of the left ventricular ejection fraction (LVEF) from 30% to 75% within 1 week. One year after the diagnosis the patient is in good health, with steady normal LVEF. The rapid recovery, which was immediately subsequent to the administration of high-dose IVIG, suggests that this kind of treatment has been effective in our patient with acute myocarditis.
