Ventricular tachycardia in acute fulminant myocarditis: medical management and follow-up.

The combination of ventricular tachycardia (VT) and severe left ventricular dysfunction presents a serious challenge in management of acute fulminant myocarditis (AFM). We report a case of a 17-month-old girl with AFM, presented with hypotension and VT, successfully treated with respiratory and inotropic support, high-dose intravenous immunoglobulin, and amiodarone. The myocardial function improved significantly within 2 weeks of treatment. The clinical course was complicated by significant amiodarone-induced hepatotoxicity, disseminated intravascular coagulation, and deep-vein thrombosis. She was later diagnosed with congenital dysfibrinogenemia and treated with chronic Lovenox therapy.
