We looked at incidence, diagnosis, treatment and outcome and any changes in these parameters during the study period were noted. Material and methods: Data were obtained from hospital records which contained echocardiographic, cardiac catheterization- and autopsy reports. Results: There were 31 children diagnosed as having transposition of the great arteries during the study period, 29 had D-TGA. Follow-up period was from 11 months to 21 years (median 13 years). The incidence was 1:3681 births and male to female ratio 2.4:1. Cardiac catheterization was used as a diagnostic tool in 11 cases, but as of 1984 all diagnoses were made by echocardiography. Of the patients with D-TGA, 21 (72%) had no additional cardiac defects, however when these were present, a ventricular septal defect was most common. Twenty-six patients (84%) underwent a balloon atrial septostomy and it was successful in 24 (92%). Twenty-three of 31 patients (74%) have had cardiac surgery, all fully corrective. Of the 23 surgeries, 21 were done in London, England. Fifteen children had atrial switch repair, a Mustard operation was done twice and Senning in 13 patients. In five cases an arterial switch operation was performed and three patients had other surgeries. Half of the patients had a difficult post operative course, however there was only one death within the first month following surgery. Of the 31 children born with TGA from 1971 to 1996, eight (26%) have died and two are lost to follow-up. All the patients that died were born during the first half of the study period. Of these eight children, four died within the first four days of life. Corrective cardiac surgery had been done on two patients before death. There are 21 patients alive which updated information is available on. All are ...
