Survival following myocarditis and myocardial calcification associated with infection by Coxsackie virus B-4.

A Coxsackie virus B-4 was isolated from a neonate with clinical sepsis and clinical evidence of myocardial dysfunction. Radiographs demonstrated the presence and subsequent resolution of myocardial calcification. Electrocardiograms showed a left bundle branch block, presumably caused by calcification in the corresponding segment of the bundle of His. This case demonstrates an unusual complication of neonatal Coxsackie virus B infection.
