Introduction

A heart transplant is an operation to replace a damaged or failing heart with a healthy heart from a donor who has recently died.

It may be recommended when a person's life is at risk because their heart no longer works effectively.

Why heart transplants are carried out

A heart transplant may be considered if you have severe heart failure and medical treatments aren't helping.

Conditions that may eventually require a heart transplant include:

If your doctor thinks you might benefit from a heart transplant, you'll need to have an in-depth assessment to check whether you're healthy enough to have one before being placed on awaiting list.

 

A cut is made in the middle of the chest. Your own heart is then removed, and the donor heart is connected to the main arteries and veins. The new heart should then begin beating normally.

Most people are able to start returning to many of their normal activities within a few months.

Your transplant team can give you advice about how long you may need to avoid certain activities during your recovery.

You'll need to have regular check-ups with your transplant team after the transplant.

You'll also need to take medications called immunosuppressants for the rest of your life. Without these medicines, your body may recognise your new heart as foreign and attack it (known as rejection).

Risks of a heart transplant

A heart transplant is a complex and risky procedure.

Possible complications include:

  • the immune system recognising the transplanted heart as foreign and attacking it (rejection)
  • the donated heart fails to work properly (graft failure)
  • narrowing of the arteries supplying the heart (cardiac allograft vasculopathy)
  • side effects from the immunosuppressant medication, such as an increased vulnerability to infections, weight gain and kidney problems

Many of these problems are treatable, although sometimes another heart transplant may need to be carried out if possible.

Outlook for heart transplants

Most people can eventually return to their normal activities after a heart transplant and experience a significant improvement in their symptoms for many years.

However, it'sa major operation and some of the complications can be life threatening.

Overall:

  • 80-90 in every 100 people will live at least a year
  • 70-75 in every 100 people will live at least five years
  • 50 inevery 100 people will live at least 10years

Some people have survived for more than 25 years after a heart transplant.
