Background: Septic cardiomyopathy (SCM) is a dynamic and heterogeneous complication of sepsis, driven by systemic inflammation, autonomic dysregulation, and microcirculatory alterations. Pediatric and adult patients share common pathophysiologic mechanisms, but age-dependent differences in cardiovascular physiology produce distinct hemodynamic responses. Methods: A structured narrative review of clinical and experimental studies published between 2000 and 2025 was conducted via PubMed and major critical care literature. Studies were included if they addressed SCM pathophysiology, hemodynamic monitoring, and therapeutic strategies across age groups, while studies focusing on non-septic cardiac dysfunction were excluded. Results: Adult SCM often presents as hyperdynamic, vasoplegic states, whereas pediatric patients more frequently exhibit hypodynamic profiles, reflecting developmental differences in myocardial reserve and autonomic regulation. Evidence suggests that isolated conventional echocardiographic parameters may underestimate myocardial impairment, whereas advanced modalities, including myocardial strain echocardiography and multimodal hemodynamic monitoring, may serve as complementary tools to detect subtle or evolving myocardial dysfunction. Pediatric evidence remains limited, and therapeutic guidance is largely extrapolated from adult studies. Conclusions: SCM should be approached as a time-dependent, physiology-driven condition, requiring repeated, integrated multimodal cardiovascular assessment to guide individualized management. Age-specific hemodynamic profiles highlight the need for standardized diagnostics, prospective validation of monitoring tools, and phenotype-guided interventions to improve outcomes in both adult and pediatric sepsis.
