Heart transplant is surgery that removes a diseased heart and replaces it with a healthy heart from a deceased donor to improve your quality of life and increase your lifespan. During a heart transplant, the patient is placed on a heart-lung machine. This machine allows the body to receive vital oxygen and nutrients from the blood even though the heart is being operated on. Surgeons then remove the patients heart except for the back walls of the atria.
