Open Heart Surgery
As the patient's chest cavity is opened, note the steam rising as the surgeon cauterizes the blood vessels. The patient is attached to a heart-lung machine that made the blood circulation while the heart is stopped. Once the heart stops beating, the arteries (arterial milk) of the chest cavity is grafted to the heart at both ends, through the blocked coronary artery. Finally, the patient is taken off of heart-lung machine. The heart begins to beat again.
