Organs are cooled and kept in a special solution while being taken to the patient. During the operation, the patient is placed on a heart-lung machine. This machine allows surgeons to bypass the blood flow to the heart and lungs. Doctors remove the patient's heart except for the back walls of the atria, the heart's upper chambers. The backs of the atria on the new heart are opened and the heart is sewn into place.
Surgeons then connect the blood vessels and allow blood to flow through the heart and lungs.
As the heart warms up, it begins beating. Sometimes, surgeons must start the heart with an electrical shock. Surgeons check all the connected blood vessels and heart chambers for leaks before removing the patient from the heart-lung machine. A transplant is considered when the heart is failing and does not respond to all other therapies, but health is otherwise good. Birth defects of the heart.
