This pilot study will support the design of a larger multicentre trial.\n\nSubjects undergoing cardiac surgery will be randomized to receive either standard of care (4:1) or all-blood cardioplegia for myocardial protection. Neither of these cardioplegia approaches would be considered investigational. Each is in use at numerous cardiac surgical centres around the world. The cardioplegia will be delivered using the Quest medical MPS system which is a Health Canada Approved device.\n\nClinical endpoints will be evalauted (rate of blood transtransfusion, ICU stay, etc…). In a subset of subjects who meet specific criteria, ventricular function will be evaluated in the operating room using the CD Leycom INCA conductance catheter system.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'minimumAge': '16 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* patients (male and female) undergoing isolated coronary artery bypass grafting,\n* isolated aortic or mitral repair or replacement, and\n* combined aortic or mitral valve repair or replacement and\n* coronary bypass grafting\n\nExclusion Criteria:\n\n* reoperation,\n* endocarditis,\n* dialysis dependant renal failure,\n* pre-operative ECMO or LVAD support,\n* contraindication to blood transfusion (ie.
