All subjects who consent to take part in the protocol and who meet the inclusion/exclusion criteria will undergo the IAD harvest following a post-induction IAD harvest calculation. IAD blood will be collected into citrate-phosphate-dextrose-adenine 1 (CPDA-1) blood bags. All subjects will receive a volume of Hespan® equal to the volume of their IAD harvest (to a maximum of 1 liter) performed as a result of the harvest calculation (0–1200 mL inclusive). Additional volume replacement required owing to IAD >1000mL will be performed with crystalloid, as required. Subjects will be randomized into one of two treatment arms (Hemolink™ arm or control arm) upon meeting a transfusion trigger for the first time while on CPB. Randomization will be administered centrally. Subjects will be transfused upon reaching predetermined transfusion triggers, reflecting a decrease in hemoglobin concentration and/or oxygenation:
