Infants born with congenital heart disease (CHD) are known to experience a distinct pattern of neurodevelopmental and behavioural impairment in later life. In this study, we scanned 64 infants with complex CHD prior to surgery, and used high-resolution structural, diffusion and susceptibility-weighted magnetic resonance imaging to understand the burden of brain lesions in a contemporary cohort. We characterised lesions and produced quantitative lesion maps, registered to a population template. We found a lower incidence of infarction than has been reported in previous comparable cohorts, and we explore the clinical reasons that may explain such variation.
