Mechanical circulatory support (ECMO and IABP) alongside antiviral therapy and steroids improved hemodynamics and ejection fraction in Influenza B-induced fulminant myocarditis.
Early suspicion and aggressive intervention with mechanical circulatory support and medical therapy can lead to recovery in rare cases of Influenza B-induced acute fulminant myocarditis.
Acute fulminant myocarditis represents a severe complication of myocarditis, necessitating early suspicion and intervention for improved patient outcomes. Influenza B-induced myocarditis remains a relatively rare entity. A young lady presented to the emergency department with symptoms of heart failure and cardiogenic shock, requiring inotropes without significant improvement. For the continued deterioration of her hemodynamics, she underwent mechanical circulatory support, including Extracorporeal Membrane Oxygenation (ECMO) and Intra-aortic balloon pump (IABP). The follow-up investigations showed positive influenza B. She was treated with antiviral therapy and steroids, resulting in gradual improvement in hemodynamics and left ventricular ejection fraction
Kannout et al. (2026) studied this question. Mechanical circulatory support (ECMO and IABP) alongside antiviral therapy and steroids improved hemodynamics and ejection fraction in Influenza B-induced fulminant myocarditis.
