Atypical onset and course in a child with fulminant myocarditis

Area of Science:

• Pediatric Cardiology
• Critical Care Medicine
• Pathology

Background:

• Fulminant myocarditis (FM) is a rare and severe form of heart muscle inflammation.
• It typically presents with rapid onset of cardiac dysfunction, often leading to cardiogenic shock.
• Pediatric cases are particularly uncommon, and fulminant presentations are unusual.

Observation:

• A five-year-old male child presented with acute symptoms including fever, vomiting, nausea, and abdominal pain.
• Electrocardiogram (ECG) revealed broad complex tachycardia refractory to medical and resuscitation efforts.
• The child unfortunately passed away within four hours of hospital admission.

Findings:

• Post-mortem histological examination confirmed diffuse myocardial infiltration, indicative of severe inflammation.
• No specific viral etiology could be identified despite extensive examination.
• The rapid progression and unresponsiveness to treatment highlight the aggressive nature of this case.

Implications:

• This case underscores the critical importance of prompt recognition and diagnosis of fulminant myocarditis in children.
• Immediate transfer to a facility equipped with advanced કાર્ડियक support (e.g., extracorporeal membrane oxygenation [ECMO] or mechanical circulatory support [MCS]) is vital.
• Timely intervention in specialized centers may improve outcomes for pediatric patients with FM, despite its rarity and severity.
