The gut microbiome plays a central role in immune regulation, metabolic homeostasis and brain development particularly during early life. Perturbations of the microbiome are common in infants with CHD due to altered gut perfusion, antibiotic exposure, feeding disruption and cardiopulmonary bypass (CPB). These changes may influence both cardiac recovery and neurodevelopment through interconnected gut-heart-brain signalling pathways.
