Relative changes in hemodynamic parameters during vertical displacement of the beating porcine heart by the Medtronic Octopus Tissue Stabilizer and the effect of head-down tilt. (BASE = pericardial control position; Cx = circumflex coronary artery; DIS = displacement of the heart by the Octopus, DIS + TREND = Trendelenburg maneuver [20 degrees head-down tilt] while the heart remained 90 degrees retracted; LAD = left anterior descending coronary artery; RCA = right coronary artery; × = mean arterial pressure; Statistical comparison with control values: ∗p < 0.05, ∗∗p < 0.01, #p < 0.001, ̂p = versus combined relative value of LAD and RCA flows.)
