In this case report, a 16-days-old boy presented with reduced feeding, vomiting, respiratory distress and pallor. He developed cardiogenic shock with cardiac arrest and was resuscitated. Echocardiography showed reduced left ventricular systolic function and he was diagnosed with enterovirus myocarditis since enterovirus RNA was found in the blood by polymerase chain reaction. After one month of hospitalization, the patient was discharged without any apparent sequelae. The condition is rare but associated with a high mortality. Early diagnosis and initiation of treatment is essential for survival.
