Off-pump coronary artery bypass grafting (CABG) tends to have a lower incidence of postoperative complications and remarkable advantages in terms of hospital stay. However, some drawbacks include higher rates of incomplete revascularization and the hemodynamic deterioration during manipulation of the heart, more occurring in the cases of posterolateral anatomical constraints and cardiac dysfunction. It leads to urgent conversion to extracorporeal circulation (ECC) and increases the mortality. Although conventional ECC with cardioplegia arrest provides bloodless immovable field, intense systemic inflammatory response may contribute to hemodynamic unstability especially in patients already with severe cardiac dysfunction.
