[Acute severe coxsackie virus B myocarditis of pseudonecrotic form. Apropos of 2 cases]. / Myocardite aiguë sévère à coxsackie virus B de forme pseudo-nécrotique. A propos de deux cas.

This study reports two cases of acute severe Coxsackie virus B4 myocarditis in which the immediate clinical signs suggested the acute phase of myocardial infarction, apparently antero-lateral in the first case in a context of cardiogenic shock and infero-lateral in the second case, in the context of acute pulmonary edema. Both cases were characterized by the severity of the initial signs. Numerous other cases of acute Coxsackie virus B myocarditis, simulating myocardial infarction, have been reported in the literature and these contexts deserve to be recognized earlier as they call for specific treatment. The immediate outcome was favorable in both cases but required massive cardiological intensive care in the first patient. Long term follow-up was excellent.
