Ambulatory Blood Pressure Monitoring in Assessment of Systemic Hypertension Following Successful Aortic Coarctation Repair

Abstract

Abstract Background Hypertension following primary coarctation repair affects up to a third of subjects. A number of studies suggest that future hypertension risk is reduced if primary repair is performed at a younger age. This study aims to assess prevalence of systemic hypertension after early coarctation repair (within the first two years of life) compared with late coarctation repair (after the first two years of life), including both catheter-based and surgical intervention using twenty-four hour ambulatory blood pressure monitoring. the study included 30 patients who underwent successful repair of aortic coarctation. All patients underwent complete history taking and clinical examination.All patients underwent full transthoracic echocardiographic study and ambulatory blood pressure monitoring. Results HTN had higher incidence in patients who underwent late coarctation repair than patients underwent early coarctation repair but difference was statistically insignificant. Conclusions Early intervention of aortic coarctation during infancy decreases the risk of late systemic hypertension. However, further studies are needed to evaluate increased risk of recoarctation after early intervention of aortic coarctation.
