Summary We have studied the effect of varying the flow of a venovenous bypass system during orthotopic liver transplantation. During these manipulations, central venous (n = 9) or pulmonary artery occlusion (n = 9) pressures were kept constant. There was no change in right ventricular systolic or diastolic function in either group, suggesting that any conformational change of the ventricle during bypass is not of functional significance. The extrapolated volume loading required to compensate for the absence of bypass is of the order of 3000 ml.
