Can you describe a heart transplant?

Yes: For people you have the most severely damaged hearts a transplant involves removng the heart and replacing it with a donor heart. Multiple heart attacks , and viral damage to the heart muscle are the most common causes.. The supply of donors, usually from severe head trauma is very limited, limiting the number of transplants that can be performed. It is a procedure of last resort.

Yes: The heart recipient has extensive damage and has failed medical and/ or surgical treatments, and possibly devices. So another heart that matches size, blood type, etc becomes available and is used as donor to replace the recipient sick heart. Use heart lung machine to support the patient while operation done.
