Successful explantation of a ventricular assist device following fulminant influenza type A-associated myocarditis.

We report a case of fulminant myocarditis associated with refractory ventricular fibrillation following influenza A infection. Histologic examination was consistent with myocarditis and serology confirmed the viral etiology. The patient was supported with biventricular assist devices for 20 days during which her refractory ventricular fibrillation resolved spontaneously. This is the first documented case of resolution of prolonged ventricular fibrillation while on a ventricular assist device. This case suggests those patients with fulminant viral myocarditis and refractory ventricular arrhythmias may be supported successfully with ventricular assist devices until myocardial recovery takes place.
