COVID-19-Associated Myocarditis in an Adolescent

Area of Science:

• Pediatric critical care medicine
• Infectious diseases
• Cardiology

Background:

• Adolescent obesity as a potential risk factor for severe COVID-19 complications.
• Septic shock presentation in pediatric patients with novel coronavirus infection.
• Myocarditis as a serious cardiac manifestation of SARS-CoV-2.

Observation:

• A 17-year-old obese male presented with a 7-day history of fever, gastrointestinal symptoms, and neck pain, leading to fluid-responsive septic shock.
• Initial diagnostic workup confirmed SARS-CoV-2 infection and revealed elevated cardiac biomarkers: troponin I and brain natriuretic peptide.
• Cardiac imaging, including echocardiography and cardiac magnetic resonance imaging, diagnosed acute myocarditis.

Findings:

• The patient's septic shock was responsive to fluid resuscitation.
• Diagnostic confirmation of acute myocarditis in the context of SARS-CoV-2 infection.
• Follow-up echocardiography one week post-discharge indicated significant improvement in cardiac function, with only residual myocardial dysfunction.

Implications:

• Highlights the critical role of early recognition and management of pediatric septic shock and COVID-19-associated myocarditis.
• Suggests that prompt medical intervention can lead to favorable cardiac recovery in adolescents with severe SARS-CoV-2 infection.
• Emphasizes the need for comprehensive cardiac evaluation in pediatric patients presenting with severe systemic illness and confirmed SARS-CoV-2 infection.
