Standard median sternotomy will be followed by procurement of the conduits. Heparin loading dose will be administered to achieve a kaolin activated coagulation time (ACT). Ascending aorta - right atrial cannulation will be performed to institute CPB and ACT will be monitored at 480 seconds or more. Standard centrifugal pump and a membrane oxygenator will be used for extracorporeal circulation (cardiopulmonary bypass). Compatible with the standard technique, systemic active cooling will be avoided and patients core temperature will remain range between 32 and 37˚C. Distal anastomoses will be performed during single aortic cross-clamp and blood cardioplegic arrest. Proximal anastomoses will be performed during aortic cross-clamp. Cold (10˚C) blood cardioplegic solution will be delivered in a 4:1 ratio. Cardioplegia will be delivered antegrade via the aortic root with or without additional retrograde administration via the coronary sinus. After cardioplegic induction (10 ml / Kg), intermittent doses (300 - 500 ml) will be administered following completion of each distal anastomosis. Heparin will be reversed using protamine sulphate in a ratio of 1:1 after weaning from CPB.
