By Mayo Clinic staffHeart 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
- Cardiomyopathy
- Valvular heart disease
- Congenital heart defect — a heart problem you're born with
- Failure of a previous heart transplant
In children, heart failure is most often caused by a congenital heart defect.
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, factors that could prevent you from having a heart transplant include:
- Being age 65 or older
- Having another medical condition that could shorten life, regardless of receiving a donor heart
- Poor blood circulation
- Personal medical history of cancer
- Being unwilling or unable to make lifestyle changes necessary to keep your donor heart healthy
