Hypoxic-ischaemic encephalopathy (HIE) remains one of the leading causes of neonatal mortality and long-term neurodevelopmental disability worldwide despite major advances in neonatal intensive care and the widespread implementation of therapeutic hypothermia. Traditionally, HIE has been viewed predominantly as a cerebral disorder, with clinical management focused largely on neuroprotection and seizure control. However, growing evidence suggests that perinatal hypoxia-ischaemia induces a complex multisystem response involving profound interactions between cardiovascular dysfunction, acute kidney injury, cerebral autoregulatory failure, systemic inflammation, and metabolic disturbances. Myocardial injury may lead to reduced cardiac output and impaired cerebral perfusion, while renal dysfunction contributes to fluid imbalance, altered drug pharmacokinetics, and amplification of inflammatory pathways that further exacerbate secondary brain injury. Therapeutic hypothermia, although neuroprotective, introduces additional physiological alterations that influence myocardial performance, systemic vascular resistance, and renal blood flow. These interdependent mechanisms have led to increasing recognition of a neonatal cardio-renal-brain axis as a central determinant of neurological recovery following perinatal asphyxia. This review explores current understanding of organ crosstalk in HIE, examines emerging biomarkers and monitoring strategies, and discusses how multimodal haemodynamic assessment may facilitate a transition from protocol-driven treatment toward precision neurocritical care in the neonatal intensive care unit.

Critical congenital heart disease (CCHD) represents one of the most time-sensitive neonatal emergencies, often requiring immediate postnatal stabilization, prostaglandin infusion, advanced imaging, catheter intervention, or cardiac surgery during the first hours or days of life. Advances in fetal echocardiography have substantially improved antenatal detection rates, creating opportunities to optimize delivery planning and improve neonatal outcomes through coordinated perinatal care pathways. Delivery in an appropriate tertiary cardiac center has been associated with improved preoperative survival, reduced cardiovascular collapse, lower rates of preoperative neurological injury, and improved neurodevelopmental outcomes in selected forms of CCHD. However, determining the optimal location and timing of delivery remains complex, particularly in regions where specialized pediatric cardiac services are concentrated within a limited number of centers. Emerging cardiac networks throughout the Middle East face unique challenges including large geographical catchment areas, variable prenatal detection rates, disparities in access to fetal cardiology expertise, limitations in neonatal transport infrastructure, and differing healthcare delivery models across public and private sectors. At the same time, rapid healthcare investment, expanding fetal medicine services, and increasing regional collaboration provide significant opportunities for improvement. This review examines current evidence regarding delivery planning for infants with CCHD, explores the role of modern cardiac networks in coordinating care, and discusses challenges and opportunities specific to the Middle Eastern healthcare environment. Strategies for optimizing prenatal diagnosis, delivery location, neonatal transport, and multidisciplinary collaboration are highlighted as essential components of future regional cardiac care systems.
