A lung transplant is a surgical procedure to replace a diseased or failing lung with a healthy lung, usually from a deceased donor. Depending on your medical condition, a lung transplant may involve replacing one of your lungs or both of them. In some situations, the lungs may be transplanted along with a donor heart.

Living-donor lung transplants are rare. This procedure can replace a child's diseased lung with a section (lobe) of a lung taken from a healthy adult — usually a parent. Two living donors are needed if the procedure is used for an adult.
