Conditions
Brief summary
The creation of a computer model to aid in a cardiac surgeons' decision-making regarding their coronary artery bypass grafting strategy. Specifically to determine which vessels are graftable, whether they should be sequential grafts, the number of grafts to perform and to further delineate the issue of competitive flows.
Interventions
Computer model will be created on the basis of each patients coronary angiogram and cardiac CT scan. Patients will have intraoperative measurements done by ultrasound of the flows down their grafts and coronary arteries as well as an additional post-operative cardiac CT scan. The intraoperative measurements will be take less than 5 minutes and will not increase cardiopulmonary bypass time. The surgeon performing the operation will show their own discretion as to what grafting procedure they will

The surgeon performing the operation will show their own discretion as to what grafting procedure they will perform. Other surgeons will be surveyed afterwards and given the information of the computer model and will be free to interpret the model at their discretion to decide what grafting strategy they would have used. This will include which vessels they would have chosen to graft, whether or not they would use sequential grafts and which conduits they would use.
