    Abstract:
    UNLABELLED: A retrospective statistical study on late blood pressure in patients operated for coarctation of the aorta have been done, in order to determine the optimum age for elective surgical treatment. Patients were considered hypertensive when their mean blood pressure exceeded the 90th percentile for their age and sex. The series included 126 isolated coarctation of the aortic isthmus operated at the CMC of the Porte de Choisy. The incidence of residual hypertension at rest in the series is as follows: age 1-5: 16,6 %;age 6-10: 34,3%; age 11-15: 47,5 %. In spite of these results there is no significative difference in the incidence by age group. A similar study by the Massachusetts General Hospital on 77 patients showed essentially the same results. A combination of both series (203 patients) which is possible because the study criteria are the same, gives the following results: age 1-5: 11,4 %;age 6-10: 31,9 %; age 11-20: 40,8 %. There is now a significative difference between age group 1-5 and the others (p Less Than 0,02). IN CONCLUSION: the optimum age for elective correction of coarctation of the aorta is 1-5 year. The incidence of residual hypertension is only 11,4 % in that group (70 % confidence limits: 6 to 20%).
