Durable left ventricular assist devices (LVADs) have transformed the management of advanced heart failure, but early post-operative management remains a time of heightened vulnerability with disproportionate impact on short-term and long-term outcomes. This article provides a practical, physiology-driven framework for intensive care unit (ICU) management following LVAD implantation, emphasizing early hemostasis and anticoagulation strategies, systematic hemodynamic assessment, and optimization of right ventricular function. Additional sections address respiratory management, dysrhythmia control, nutrition, and early mobilization as essential components of recovery. By synthesizing contemporary evidence with bedside decision-making, this guide aims to support multidisciplinary ICU teams in standardizing care.
