Myocarditis is an inflammatory myocardial disease secondary to autoimmune, toxic, and infectious diseases. Among the latter, virals are the most frequent. However, influenza A H1N1 virus remains a poorly reported etiology. The prevalence of fulminant myocarditis due to seasonal influenza has been established between 1 and 11% according to the diagnostic criteria used, and the prevalence of myocarditis caused by H1N1 is estimated at 13%. We report a clinical case, of a young patient, where a retrospective diagnosis of H1N1 Influenza A myocarditis was made with a presentation of fulminant myocarditis, with suggestive electrocardiographic abnormalities, positive cardiac troponins, loss of ventricular function with subsequent recovery, and microbiological isolation of the causal agent.

Keywords : myocarditis; Influenza A H1N1.
