[Fulminant influenza type A associated myocarditis: a fatal case in an 8 year old child].

Fulminant Influenza type A-associated myocarditis are very rare in children. The clinical presentation is non specific, like flu illness, cardiogenic shock or sudden cardiac arrest. We report the case of a eight years old girl with a fulminant Influenza A-associated myocarditis with a fatal evolution despite the use of an extracorporeal membrane oxygenation (ECMO). The aim of this observation is to remind that influenza in children, usually considered as a benign illness, can exceptionally be complicated by a fulminant myocarditis. Because the possibility to recover a full myocardial function, the persistence of severe heart failure despite the medical treatment should conduct rapidly to a mechanical circulatory assistance.
