Also known as اوپن ہارٹ سرجری
Open-heart surgery is any type of surgery where the chest is cut open and surgery is performed on the muscles, valves, or arteries of the heart.During this surgery, a healthy artery or vein is grafted (attached) to a blocked coronary artery. This allows the grafted artery to “bypass” the blocked artery and bring fresh blood to the heart.
