Does surgical correction of coarctation of the aorta in adults reduce established hypertension?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether surgical correction of coarctation of the aorta in adults (>16 years) results in reduction in established hypertension. Altogether 484 relevant papers were identified using the below mentioned search, 11 papers represented the best evidence to answer the question. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses were tabulated. We conclude that surgical repair of coarctation of the aorta in adult patients is superior to conservative management in the reduction of established hypertension, with one meta-analysis and several retrospective reviews reporting low morbidity and low risk of re-stenosis. The reduction in blood pressure postoperatively has been demonstrated consistently, with most patients reported as normotensive without medication and the remainder having reduced requirements for antihypertensive medications. In all the papers included here (except one), there was no early mortality and no procedure-related late mortality during mean follow-up ranging from 2 to 14 years. Thus, surgical correction of aortic coarctation is a relatively safe procedure.
