A heart-lung transplant is a major and rarely performed surgical procedure where a person's diseased heart and lungs are replaced with those of a recently deceased donor.
On average, only six heart-lung transplants are performed in the UK each year.
This is because there are very few suitable donor organs available and priority is generally given to people who only need a Heart transplant.
A heart-lung transplant is the only treatment available for people who have combined heart and lung failure when all other treatment options have failed.
The conditions that most often require a heart-lung transplant are:
Occasionally, a heart-lung transplant may be used to treat cystic fibrosis, a condition where the lungs and digestive system become clogged up with sticky mucus.
The total number of available donor hearts and lungs is very small and thetransplant operation places a major strain on the body. This means a heart-lung transplant will only be recommended after very careful consideration and an in-depth assessment of your physical and mental health.
Aperson is usually only considered to be a suitable candidate for a transplant if they are in relatively good health and have no other serious medical problems.
For example, a heart-lung transplant may not be recommended if you are elderly, have cancer, misuse alcohol or drugs, smoke, are obese, or have a long-term mental health condition.
Specific criteria for people requiring a heart-lung transplant are currently being developed. For now, recommendations are made after consultation with a panel of transplant experts and members of your transplant team.
If it's thought you might benefit from a heart-lung transplant, you'll be asked to have an assessment in hospital to check whether you are a suitable candidate for the procedure.
This will involve a number of tests, which may include blood tests, urine tests, blood pressure tests, lung and heart function tests, X-rays and scans.
If a heart-lung transplant is recommended after your assessment, you'll go on the transplant list to wait until suitable donor organs become available. The length of time spent on the waiting list can vary, but it can be several months or even years.
When a set of donor heart and lungs becomes available, you'll be admitted to hospital for the operation, which usually takes several hours to complete. Most people need to stay in hospital for around three weeks after the procedure.
The main risk after a heart-lung transplantis your immune system recognising the donated organs as not belonging to you and attacking them, which can stop the organs working properly.
This can often be avoided by taking medication to suppress your immune system. However, these medications themselves cancause side effects, such as high blood pressure and increased vulnerability to infections.
For those who survive to one year, the outlook is generally quite good, with most people surviving for at least 10 years and some people potentially living for 25 years or more.
However, it's important to realise that survival rates are a guide and cannot predict outcomes for each person. There are many factors that could influence your ownpredicted survival, such as your age.
Your transplant team will be able to provide you with more detailed information.
Finding out that you need to have a transplant, waiting for suitable donor organs to become available, andactually having the transplant can be emotionally demanding for both you and your family. Most transplant teams are able to offer counselling for this.
Alternatively, your GPmay be able to refer you to a counsellor and provide you with information and advice about joining a support group in your area.

If a heart-lung transplant is thought to be a potential treatment for you, you'll be asked to have an assessment before potentially being placed on the transplant waiting list.
Following a heart-lung transplant, you'll probably need to stay in a hospital intensive care unit (ICU) for a few days. This is because: you'll need to be carefully monitored to make sure the organs are working, there's a risk your body may suddenly reject the new organs, etc.
One of the biggest risks after having a heart-lung transplant is that, despite taking immunosuppressants, your body will reject the new heart and lungs.
