A heart transplant is an operation in which a diseased, failing heart is replaced with a healthier donor heart. A heart transplant is a treatment that's usually reserved for people whose condition hasn't improved enough with medications or other surgeries.

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:

A weakening of the heart muscle (cardiomyopathy)
Coronary artery disease
Heart valve disease
A heart problem you're born with (congenital heart defect)
Dangerous recurring abnormal heart rhythms (ventricular arrhythmias) not controlled by other treatments
Failure of a previous heart transplant
