Do children with myocarditis have better survival and ventricular remodeling outcomes compared to children with idiopathic dilated cardiomyopathy?
In children, myocarditis is associated with more favorable survival and ventricular remodeling outcomes at 3 years compared to idiopathic dilated cardiomyopathy.
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.
