Appointments and care

At Mayo Clinic, we take the time to listen, to find answers and to provide you the best care.

Heart transplants are performed when other treatments for heart problems haven't worked, leading to heart failure. In adults, heart failure can be caused by:

  • Coronary artery disease
  • A weakening of the heart muscle (cardiomyopathy)
  • Valvular heart disease
  • A heart problem you're born with (congenital heart defect)
  • Failure of a previous heart transplant

In children, heart failure is most often caused by either a congenital heart defect or a cardiomyopathy.

A heart transplant isn't the right treatment for everyone, however. Certain factors may mean you're not a good candidate for a heart transplant. While each case is considered individually by a transplant center, a heart transplant may not be appropriate if you:

  • Are age 65 or older
  • Have another medical condition that could shorten your life, regardless of receiving a donor heart
  • Have serious blockages in the arteries in your arms or legs (peripheral artery disease)
  • Have a personal medical history of cancer
  • Are unwilling or unable to make lifestyle changes necessary to keep your donor heart healthy, such as not drinking alcohol or not smoking

For some people who can't have a heart transplant, another option may be a ventricular assist device (VAD). A ventricular assist device is a miniature pump implanted in your chest that helps pump blood through your body. VADs are commonly used as a temporary treatment for people waiting for a heart transplant, but are increasingly being used as a permanent treatment for heart failure.
