COVID-19 infection with complicated fulminant myocarditis: a case report

Area of Science:

• Cardiology
• Infectious Diseases
• Neurology

Background:

• The 2019 coronavirus disease (COVID-19) pandemic has led to a wide range of clinical manifestations.
• Myocarditis and myositis are known, though less common, complications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Observation:

• A young female patient presented with fulminant myocarditis, leading to severe heart failure and myositis.
• The patient required advanced hemodynamic support with an intra-aortic balloon pump (IABP).
• Immunomodulatory therapy was initiated to manage the inflammatory response.

Findings:

• Following treatment, the patient's vital signs stabilized, and the IABP was successfully removed.
• Cardiac and skeletal muscle magnetic resonance imaging revealed significant edema, confirming myocardial and muscular injury.
• The case underscores the potential for severe, multi-systemic inflammatory complications following COVID-19.

Implications:

• This case highlights the critical need for heightened clinical awareness of severe cardiac and muscular complications in COVID-19 patients.
• Early recognition and aggressive management, including mechanical circulatory support and immunomodulation, may be crucial for improving outcomes.
• Further research is warranted to understand the mechanisms and long-term sequelae of COVID-19-induced myocarditis and myositis.
