§ Mr. Freeman
This information is not identifiable from data collected centrally. Returns of the United Kingdom cardiac surgery register show that 137 A-V canal operations were performed in 1985. We do not have information on the proportion of these operations which involved children with Down's syndrome, or the hospitals in which such operations took place.
§ Mr. Freeman
Information is not available in exactly the form requested. Table 1 shows the number of deaths of children aged 0–14 registered in England and Wales in 1983–87 to which endocardial cushion defects (International Classification of Diseases 9th revision 745.6), which includes A-V canal defect, was assigned as the underlying cause of death.
For 1985 and 1986 all causes of death were coded, and information on the number of certificates mentioning endocardial cushion defects is consequently available. Table 2 shows, for those deaths registered in 1985 and 1986, how many death certificates for 0–14 year olds contained a mention of ICD 745.6 (irrespective of whether or not it was assigned as the underlying cause of death), and how many of those also contained a mention of Down's syndrome (ICD 758.0). Similar information is not available for the other data years.191W
