Histology and Explanation of Acute viral myocarditis

Myocarditis is an inflammation of the myocardium. Acute viral myocarditis is produced most often by Coxsackie B virus and echovisuses. Myocardial interstitium presents an abundant edema and inflammatory infiltrate, mainly with lymphocytes and macrophages. Focal destruction of myocytes may be present, generating loss of contractile function of the myocardium.
