Key result
Influenza B infection in a previously healthy 5-year-old girl led to severe acute myocarditis and fulminant heart failure requiring extracorporeal membrane oxygenation.
Influenza B can cause fulminant myocarditis and severe acute heart failure requiring ECMO support in previously healthy children.
Highlights potential for rapid deterioration in pediatric influenza B myocarditis; leaves open optimal management and incidence data.
Influenza B is a common viral illness in childhood. We report a 5-year-old previously healthy girl admitted with facial edema that developed severe acute myocarditis from influenza B infection. As her clinical course progressed, she ultimately developed severe, acute heart failure requiring extracorporeal membrane oxygenation for support.
