Ventricular Remodeling and Survival Are More Favorable for Myocarditis Than For Idiopathic Dilated Cardiomyopathy in Childhood

Abstract

Children with biopsy-confirmed or probable myocarditis had similar proportions of death, transplantation, and echocardiographic normalization 3 years after presentation and better outcomes than those of children with idiopathic dilated cardiomyopathy. In children with myocarditis who had impaired LV ejection at presentation, rates of echocardiographic normalization were greater in those without LV dilation and in those with greater septal wall thickness at presentation.
