Abstract

Minimal Invasive Extracorporeal Circulation (MIECC) systems are advanced perfusion technologies developed to reduce hemodynamic disturbances, systemic inflammatory response, and perioperative complications associated with conventional cardiopulmonary bypass. MIECC features a closed, heparin-coated, miniaturized circuit without a venous reservoir, minimizing priming volume and reducing blood contact with artificial surfaces, thereby controlling systemic inflammatory response. Optimized circuit design also contributes to the preservation of perioperative hematocrit levels, maintenance of oxygen-carrying capacity, and reduction of transfusion requirements. Technical improvements in MIECC include blood-activated suction devices, cellular blood recovery (cell saver) systems for postoperative autotransfusion, and modular circuit designs. Clinical studies and meta-analyses have shown that MIECC reduces postoperative morbidity, preserves renal and myocardial function, and decreases inflammatory markers. The closed circuit and low priming volume further reduce heparin requirement, minimize bleeding risk, and enhance patient safety. This review details the technical characteristics, application methods, and clinical advantages of MIECC systems, highlighting their potential role and benefits in cardiac surgery based on current evidence.
