Usually organs are just transplanted the once, since transplanting them again would increase the chances of organ failure for the next person to get it (particularly if it were a heart). Also, for an organ such as the kidneys, if they are transplanted once they will also be subjected to having to filter out many immunosuppressants and other drugs that the patient is required to take. Over time this does diminish their function, making them unsuitable for retransplantation.

It is called organ rejection, which occurs when the recipient's immune system recognizes the transplanted organ as foreign and tries to attack and destroy it. Organ rejection can lead to the failure of the transplanted organ if not managed properly with immunosuppressive medications.

T cells and antibodies are two primary substances produced by the body that are responsible for rejection of a transplanted organ. T cells recognize the transplanted organ as foreign and mount an immune response, while antibodies can target the transplanted tissue for destruction. These responses can lead to rejection if not controlled by immunosuppressive medications.
Doctors can ensure that a transplanted organ works successfully by carefully matching the donor and recipient, prescribing immunosuppressant medications to prevent rejection, closely monitoring the recipient for signs of rejection or infections, and providing long-term follow-up care to maintain the health of the transplanted organ.
