Surviving Pediatric Cardiogenic Shock: Clinical Approach, Improving Outcomes, and Future Directions: A Scientific Statement From the American Heart Association.

Pediatric heart failure-related cardiogenic shock carries high morbidity and mortality but is understudied. Improving outcomes in pediatric cardiogenic shock hinges on timely diagnosis and appropriate triage, medical management tailored to the cause and phenotype of cardiogenic shock, and optimal timing of escalation to appropriate mechanical circulatory support. This scientific statement provides a diagnostic framework for the bedside clinician, in addition to proposing a pediatric cardiogenic shock definition and severity staging aligned with systems previously validated in other studies. It outlines the initial approach to diagnosis and stabilization of a child with suspected cardiogenic shock and offers guidance on optimal noninvasive and invasive monitoring strategies to determine clinical trajectory because a significant proportion of children with cardiogenic shock will continue to deteriorate in the first 24 hours. Last, it identifies future directions for the field, including educational interventions for the frontline clinicians seeing these patients, studying the role of a multidisciplinary shock team, evaluating the prognostic and clinical relevance of known and novel biomarkers, and leveraging all these to develop clinical decision tools or algorithms to guide nuanced management of these patients.
