Categorical variable (sex) is presented as counts with percentages. Continuous variables are presented as medians and interquartile range. Note that P values correspond to comparisons between each CHD group (BiV, TGA, SV) and controls. BiV, Biventricular heart disease without transpostion of the great arteries; TGA, d-transposition of the great arteries; SV, single-ventricle heart disease; NA, not applicable; SaO2, arterial saturation; CPB, cardiopulmonary bypass; RCP, regional cerebral perfusion; CICU, cardiac intensive care unit.
