AO, aortic cross clamping; AVR, aortic valve replacement; BiVAD, biventricular ventricular assist device; CABG, coronary artery bypass grafting; CABG + VR, CABG combination with a valve replacement; CPB, cardiopulmonary bypass; IABP, intra-aortic balloon pump counter-pulsation; LVAD, left ventricular assist device; MVR, mitral valve replacement; RVAD, right ventricular assist device.
