Post-cardiotomy shock represents a critical challenge in cardiac surgery, requiring precise hemodynamic assessment and multidisciplinary management. Diagnosis relies on the SCAI Shock Staging System, which categorizes patients from at-risk to extremis based on perfusion and end-organ dysfunction. Effective management necessitates evaluating the entire cardiovascular system—specifically right and left ventricular function and valvular integrity—rather than focusing solely on left ventricular ejection fraction. Preoperative optimization, including diuresis and the judicious use of mechanical circulatory support, significantly improves outcomes. When pharmacologic support with vasoactive agents proves insufficient, escalating to temporary mechanical circulatory support requires a team-based approach involving cardiac surgeons, heart failure specialists, and intensivists. Standardizing care through early recognition, shock team activation, and clear communication between the operating room and the cardiac intensive care unit remains essential to reducing mortality in this high-risk patient population.
