Myocarditis in children is generally caused by a viral infection, which means viral myocarditis is the most common type. This condition indicates that the virus has damaged the myocardial cells, leading to severe symptoms such as heart failure and cardiogenic shock. Once myocarditis is diagnosed in a child, it is crucial to hospitalize and treat them actively. While treating myocarditis, it is essential to use medications that nourish the myocardium and actively treat the primary disease. Most children with myocarditis have a favorable prognosis, but fulminant myocarditis has a poor prognosis, carrying a certain risk of mortality.
