Perioperative hemodynamic measurements using a pulmonary artery catheter (Edwards Lifesciences). There are no significant differences between the two groups at most time points (p > 0,05), few differences (p < 0,05) have no clinical significance because the corresponding values remain in the normal range. a: Pulmonary vascular resistance (PVR), y-axis in [dyne*sec/cm⁵]; b: Cardiac index (CI), y-axis in [l/min/m² BSA]; c: Pulmonary capillary wedge pressure (PCWP), y-axis in [mmHg]. "OP-0", skin cut; "OP-1", post Mini-HLM/OPCAB-stabilizer; "OP-2", skin closure; “ICU-1”: one-hour post-op; "ICU-2": six-hour post-op; "ICU-3”: 12-hour post-op; "ICU-4": 24-hour post-op.
