After updating current evidence on the use of cardiac troponins (cTn) in the context of CHD for risk stratification at early ages, we discuss relevant issues, starting from the evidence that only the measurement of the cTnT form is useful in this population.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Content<\/jats:title>\n                  <jats:p>In newborns\/infants with CHD, the cTnT concentration increase is correlated with: (a) cardiac stress and hemodynamic parameters, but not with the type of CHD; (b) volume overload\/right ventricular pressure overload; (c) postoperative hypoperfusion injury and mortality; and (d) effects of cardioprotective strategies. For infants with CHD, high-sensitivity cTnT (hs-cTnT) concentrations &amp;gt;25\u2005ng\/L are an independent predictor of poor outcomes. Transitioning from cTnT to hs-cTnT in newborns\/infants improves the identification of: (a) physiopathological mechanisms and factors that increased hs-cTnT early after birth; (b) myocardial injury, even when subclinical; (c) identification of patients requiring immediate therapeutic interventions; and (d) 99th percentile upper reference limits (URLs). However, no reliable URLs are currently available to allow the detection of myocardial injury associated with CHD in newborns\/infants.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Summary<\/jats:title>\n                  <jats:p>Additional data evaluating the clinical value of hs-cTnT in the risk stratification of newborns\/infants with CHD who may suffer myocardial injury is needed. Validating the measurement, possibly in amniotic fluid samples, and improving the interpretation of hs-cTnT concentrations in the prenatal period, at birth and within 1 year of age are crucial to change CHD mortality\/morbidity trends in the pediatric population.<\/jats:p>\n
