Answer:
Open heart surgery is a type of surgery where the chest is cut open and surgery is performed on the muscles, valves or arteries of the heart.
According to NHLBI it is most common type of surgery done on adult.
During this surgery a healthy artery or vein is grafted to a blocked coronary artery.This allow the grafted artery to "bypass"the blocked artery and bring fresh blood to the heart.
