What are the risks of an organ transplant?
Potential for a blood transfusion due to blood loss in the operating room and related risk for the transmission of infectious diseases from a blood donor. Blood donors are screened very carefully, but there may be a rare case when a disease may be undetectable and may be passed to the recipient.
Why are transplants risky?
Hyperacute rejection is usually caused by specific antibodies against the graft and occurs within minutes or hours after grafting. Acute rejection occurs days or weeks after transplantation and can be caused by specific lymphocytes in the recipient that recognize human leukocyte antigens in the tissue or organ grafted.

Infection. Transplant patients are at a greater risk of infection because of the need for immunosuppression, which weakens their immune system and ability to fight infection.

The donor heart may have a pre-existing heart disease that worsens after transplantation. But one of the most common reasons a transplanted heart fails is rejection by the recipient's immune system, which attacks the new heart as a foreign object.
