The heart is undeniable, the most important organ, which is responsible for sustaining life and acts as the body's engine room. It delivers the blood all around the body parts and delivers oxygen and essential nutrient via blood. You can also say that heart is the hardest-working organ of the human body, which weighs around 200 to 425 grams. It also pumps the deoxygenated blood to the lungs and oxygenated blood to the body parts. Now when you know about the role of the heart, thus you can presume well that risking heart health is, actually risking your life.

Unfortunately, in some of heart patients, where there are possible chances of heart failure, or where the heart got weakened and unable to pump blood, the heart is severely damaged, and also where the other treatment options have been failed to treat the heart conditions. In such conditions, the improper functioning heart is replaced by the healthier heart of the matching donor. However, not all patients are eligible for heart transplant surgery.
