Brief Summary

The objective is to determine the effectiveness of pulsatile flow during cardiopulmonary bypass to reduce the incidence of acute kidney injury after cardiac surgery. Investigators will also evaluate the safety and impact of pulsatile flow on clinical outcomes compared to non-pulsatile flow during cardiopulmonary bypass.
