Stroke Study: Operative Strategies to Reduce Cerebral Embolic Events During Coronary Artery Bypass Surgery

No aortic clamp used in this group. The aortic clamp is a standard cardiac surgical instrument used during cardiac operations, not a specific device used for this study.

The partial-occluding clamp is a standardized instrument used during coronary artery bypass surgery, it is not a specific device for this study.

The proximal anastomoses performed under single clamp is an alternative method during coronary artery bypass surgery. The single clamp essentially means that whole operation is done using the cross clamp, which is a standard instrument during cardiac operations, not a specific device for this study.

Both an aortic cross clamp and partial occluding clamp are used in this arm. Neither the cross clamp nor the partial clamp are specific devices for this study but are standard cardiac surgical instruments used during coronary artery bypass surgery and cardiac surgery.
