Myocarditis with Biventricular Dysfunction Caused by Parvovirus B19 – A case report

ABSTRACT Introduction: Myocarditis is often a diagnostic challenge given the heterogeneity of the clinical presentation. Cardiac magnetic resonance imaging is an important diagnostic tool required for the diagnosis as well as detecting the prognosis of the patient. Although rarely used, an endomyocardial biopsy is the gold standard diagnostic method. Clinical case: We present the case of a 29-year old man diagnosed with myocarditis who later developed severe depression of biventricular systolic function. An endomyocardial biopsy was performed, which revealed a parvovirus B19 infection. After treatment of the left ventricular dysfunction, the global systolic function was recovered.
