[Myocarditis in the differential diagnosis of cardiomyopathies. Endomyocardial biopsy or MRI?]

Parvovirus B19 Myocarditis of Fulminant Evolution

Myocarditis is an inflammation of the myocardium. Clinical presentation ranges from non-specific systematic symptoms to fulminant collapse and sudden death. Sudden death occurs at rates of 8.6-12% and cardiomyopathy at 9%. In active myocarditis, there is inflammatory cellular infiltrate with myocardial necrosis. The disease is distinguished by clinical presentation in fulminant and non-fulminant myocarditis. We present a rare case of a parvovirus B19-induced fulminant viral myocarditis in a young female. The patient presented with acute onset heart failure mimicking a myocardial infarction, followed by non-specific symptoms that had been misdiagnosed as urinary tract infection.
