Arterial hypertension in patients with repaired coarctation and hypoplastic aortic arch

At present, surgical techniques for treatment of CoA are well established and the mortality is one of the lowest amongst all CHD patients. Nevertheless, the incidence of arterial hypertension (AH), cerebrovascular disease and heart disease is still high even in those patients who have no signs of re-coarctation and deformity of aorta. According to several modern studies, these problems are thought to be due to microstructural changes of the aortic wall (disorders of the collagen-elastic carcass), malfunctions of the aortic baroreceptors and unnatural geometry of the aorta after surgery. This study was designed to analyze the possible causes of residual AH after surgical treatment of coarctation and hypoplasia of the aorta. A high incidence of residual AH is still a topical issue for this group of patients and requires further research of pathogenesis and optimal therapies of this disorder.
