ASD = atrial septal defect; AV canal = atrioventricular canal; CPB = cardiopulmonary bypass; ICU = intensive care unit; peak level (highest level of troponins on the multiple measurements after surgery) is the highest value; ns = not significant; SMSR = supra mitral stenosing ring; TOF = tetralogy of Fallot; TVR = tricuspid valve repair; VSD = ventricular septal defect All values are in mean (standard deviation) unless specified. p-values are between the two age groups compared
