During traditional CABG, what occurs after the heart is arrested?

• A. The grafting procedure begins
• B. The sternum is closed
• C. Pacemaker wires are placed
• D. The patient is weaned from the bypass machine

Answer: (A)

After arresting the heart with cardioplegia, the grafting work begins. With the heart quiet, the surgeon can sew the grafts to the coronary arteries and the aorta without the motion of a beating heart, ensuring precise, secure connections. The bypass machine keeps the body perfused during this period. Only after all planned grafts are in place is the cross-clamp removed, the heart allowed to resume beating, and the team proceeds to wean from bypass and close the chest. Pacemaker wires are typically addressed later if needed.
