Short-Term Outcomes of Acute Fulminant Myocarditis in Children

Abstract

Data on the clinical profile, echocardiographic findings, and outcome of acute fulminant myocarditis (AFM) in children from resource limited countries are limited. To study the clinical profile and short-term outcomes of children aged 2 months to 17 years with AFM managed with only supportive care. We enrolled all children admitted with AFM in our hospital from January 2009 to October 2010. Although the information on patients admitted from January 2009 to March 2010 were retrieved from the case records, data of children admitted from April 2010 were recorded prospectively. AFM was diagnosed based on clinical and echocardiographic criteria. We collected information regarding clinical course, treatment details, and echocardiography findings using a structured performa. All of the children, including those for whom baseline information was collected from the records, were followed-up prospectively to determine short-term outcomes. A total of 10 children, of whom 6 were male, presented with AFM. Their median age was 7.5 (interquartile range [IQR] 2 to 13) years, and the mean left-ventricular ejection fraction (LVEF) was 26% (SD 11.5). Of the 10 children, 9 were discharged, and 1 child died. At discharge, all children showed improvement in the symptoms, but only 4 had improvement in LV function on echocardiography. Factors associated with poor recovery of LV function at discharge were anasarca, low LVEF, and increased serum glutamate pyruvate transaminase levels at admission. One child had died at 2-month follow-up, and another child developed dilated cardiomyopathy at 15 months after discharge. Children with AFM had good immediate- and short-term outcomes even without the use of mechanical assist devices. Decreased LVEF at admission was found to be one of the most important determinants of poor immediate outcomes in these children.
