Successful transplantation after long-term preservation of dog hearts

Nucleoside transport inhibition is a new approach to long-term preservation of donor hearts. To evaluate its effectiveness, the following were tested: 1) the effect of nucleoside transport inhibition on high-energy phosphate content after cardioplegic arrest and during long-term cold storage (group I: cardioplegia, control [n=18]; group II: cardioplegia plus nucleoside transport inhibitor [n=18]
