<unk><unk>  <unk> i) transplantation is a method of allocation in organ transplantation that permits more efficient use of available organs regardless of<unk>  blood type, which would otherwise be unavailable due to hyperacute rejection. Primarily in use in infants and young toddlers, research is ongoing to allow for increased use of this capability in adult transplants. Normal<unk> -compatibility rules may be observed for all recipients. This means that anyone may receive a transplant of a type-O organ, and consequently, type-O recipients are one of the biggest beneficiaries of<unk><unk>  transplants. While focus has been on infant heart transplants, the principles generally apply to other forms of solid organ transplantation. __TOC__
