Respiratory syncytial virus myopericarditis in an immunocompetent adolescent

Respiratory syncytial virus infection is responsible for seasonal outbreaks, usually manifested with acute respiratory disease in childhood. Acute myocarditis is a rare and underdiagnosed complication of this infection. Myocarditis has a heterogeneous clinical presentation and is related to an increased risk of ventricular arrhythmias, sudden death, and chronic dilated cardiomyopathy. This paper is a case report of confirmed myocarditis associated to respiratory syncytial virus in an immunocompetent adolescent, not classified in typical risk groups. A review of the management of myocarditis is presented, with an emphasis on diagnosis, risk stratification, etiological assessment, and treatment options.
