Late Results of Surgical Repair for Tetralogy of Fallot and Corrected Transposition of the Great Arteries at the Mayo Clinic
Between 1955–1970, there were 681 surgical survivors of complete repair of tetralogy of Fallot at the Mayo Clinic. Age at correction varied from infancy to adulthood, but 84% of patients were 5 years of age or greater at time of repair. Late follow-up information was obtained in 1977. For patients who underwent surgery between 1955–1964, the period since surgery ranged from 12–22 years, with a mean of 16.5 years. For the other subgroup of patients who underwent surgery between 1965–1970, the range of follow-up was 6–12 years, with a mean of 9 years. Follow-up information was obtained from all but 7 of the 681 total surgical survivors.
