Keywords: Cardiovascular, Myocardium, Myocarditis, LGE, troponinPediatric myocarditis is associated with major morbidity and mortality. Biomarkers are needed to predict clinical outcomes. High-sensitivity troponin (hs-TnT) and late gadolinium enhancement (LGE) have been shown to correlate with poor outcomes in adult populations. We found that LGE and hs-TnT linearly correlated with each other in our pediatric population, and that children with myocarditis were more likely to be male, have a higher LGE score, higher hs-TnT values, and increased T2 signal intensity than those who did not. A cut-off of 1200 ms for native T1 global mean was significantly associated with the need for inotropic support.
