Fulminant myopericarditis in an immunocompetent adult due to pandemic 2009 (H1N1) influenza A virus infection

AbstractAcute myopericarditis is a well-recognized but rare complication of numerous viral infections. Here we report a case of fulminant myopericarditis presenting with acute heart failure and a state of shock in a previously healthy young woman. H1N1 influenza A virus sequences were identified in throat and pericardial fluid, suggesting a viral source of the infection.
