Key result
Influenza A and B viruses are a well-documented but uncommon etiology of acute myocarditis in pediatric patients, which can present with severe hemodynamic compromise.
Why the study?
Influenza A and B viruses are an uncommon cause of acute myocarditis with variable presentations, prompting a report to emphasize considering this etiology in children.
Case Report
Highlights the importance of considering influenza as a potential etiology for acute myocarditis in pediatric patients, given its potentially fulminant course.
Influenza myocarditis warrants vigilance in pediatric cases with cardiac symptoms; leaves open optimal diagnostic and management strategies.
Acute myocarditis is a rare but potentially fatal disease. Endomyocardial biopsy and histologic examination are key to an accurate diagnosis. Despite being an uncommon cause, Influenza A and B viruses are a well-documented aetiology. Myocarditis may complicate about 0 to 10% of influenza virus infections (0.4 to 5% in paediatric cases). The clinical presentation varies widely, from ischemic-like chest pain to fulminant myocarditis with acute hemodynamic compromise, requiring mechanical circulatory support, with high mortality in the acute phase. We report a series of paediatric patients with myocarditis due to Influenza virus, to emphasize the importance of considering this uncommon aetiology.

Dolader et al. (2021) conducted a case report in Influenza myocarditis. Influenza virus infection was evaluated. Influenza A and B viruses are a well-documented but uncommon etiology of acute myocarditis in pediatric patients, which can present with severe hemodynamic compromise.
