Sympathetic reinnervation of cardiac allografts evaluated by 123I-MIBG imaging.

Abstract

Sympathetic reinnervation increases with time after heart transplantation and is seen more frequently after 2 y post-transplantation. Complete reinnervation of the transplanted heart does not occur even up to 12 y post-transplantation. Early vasculopathy may delay the process of sympathetic reinnervation.
