    Abstract:
    This article describes a retrospective investigation concerning the occurrence of hypertension in 65 patients who, between 1975 and 1990, underwent surgical repair of coarctation of the aorta. The objective of the study was to investigate the incidence of hypertension after operative correction of coarctation of the aorta. In addition an attempt was made to find a correlation between recoarctation, age at surgery, surgical technique and associated intracardiac malformations, and the presence of persistent postoperative or late occurring hypertension. Eighteen of the 65 patients (27.7%) appeared to be hypertensive 3 to 13 years (mean 5.2 years) after the operation. In only 3 patients hypertension could be explained by restenosis at the coarctation repair site. In 60% and 34.3% of the patients a correlation existed with the presence of a hypoplastic aortic arch and serious additional intracardiac anomalies, respectively. On the basis of these findings early operative treatment of coarctation of the aorta seems to be indicated, especially when the coarctation is associated with hypoplasia of the aortic arch or with complex intracardiac anomalies. Because of the relative small number of patients that underwent operative correction of coarctation of the aorta beyond the first year of life a correlation between the postoperative occurrence of hypertension and the age at operation was not found.
