    Cardiopulmonary bypass (CPB) disrupts microcirculation, leading to tissue hypoxia despite normal systemic hemodynamics.

  • 2

    Endothelial dysfunction and glycocalyx shedding during CPB are significant contributors to microvascular impairment.

  • 3

    Current microcirculatory assessment tools face technical challenges and lack standardized endpoints for clinical use.

  • 4

    Cardioprotective strategies during CPB include mechanical approaches, ischemic preconditioning, and pharmacologic interventions.

  • 5

    Translating findings from experimental models to clinical practice remains challenging, highlighting the need for better integration of imaging and biomarkers.
