Retx Rẹtrànsplantatỉori. cardiomyopathy and patients with coronary artery disease i Figures 5 and 6 present the indications for pediatric heart transplantation age 16 years first as overall indications indications by year for the two major indications and finally indications by age of the recipient. Congenital heart disease is the most common indication for transplantation in the pediatric population and has been since 1989 As anticipated congenital heart disease makes up close to 75 of the transplan-tations in the less than I year age group yet less than 30 in the older aged children. Figure 7 presents the actuarial survival rate after heart transplantation over a 13-vear period. Tile overall 1-year survival rate for heart transplantation is 79 . The patient Á life time to 50 survival is years and in those surviving the first year the patient Ạ life is years. The falloff in survival is almost a straight line from year 1 through 14 with a constant mortality rate of 4 per year. The next series of figures represent actuarial survival rates for year of transplantation recipient age and retransplantation. Figure 8 demonstrates 5-year actuarial survival rates over the past 17 years broken down in 3-year time blocks. There was a substantial increase in more recent patients compared with those who underwent transplantation from 1980 to 1985. There is a marginal but statistically significant further increase in survival rates comparing the last 5 years of the 1980s with patients who underwent transplantation from Years Post Transplantation Figure 7.
