Background: Severe heart failure or cardiogenic shock might arise as a consequence of fulminant myocarditis if it manifests and advances swiftly. The effective implementation of an immunological modulation regimen and mechanical circulatory support has proven instrumental in preserving the lives of individuals experiencing hemodynamic disturbance.
Case Presentation: The current report described a severe instance of fulminant myocarditis in an 18-year-old young woman who presented with severe hypoxemia and hemodynamic instability. The patient was treated with a combination of optimal medical therapy, immunological modulation, extracorporeal membrane oxygenation (ECMO), and an intra-aortic balloon pump (IABP) to support him through his critical period of hemodynamic collapse.
Conclusion: The case presented herein underscored the prompt reversal of life-threatening fulminant myocarditis subsequent to a comprehensive treatment regimen encompassing optimal medical therapy and aggressive mechanical circulatory support.
