Acute and intermediate-term outcome of endovascular stenting of native aortic coarctation in adolescents and adult patients

Abstract

Introduction Coarctation of aorta (CoA) is a common form of cardiac lesions requiring intervention. Recently, endovascular management with stent implantation has emerged as the preferred strategy. We aim to report our single-center experience of stenting in a wide range of patients using different types of stents and later on its complications. Patients and methods Between January 2012 and December 2017, 56 patients who underwent treatment with stents for CoA were retrospectively studied. All the patients underwent echocardiography and computed tomography scans at 6–12 months follow-up. Results There were 18 women and 38 men with a mean age of 23.24±15.75 years (range, 9–55 years). The median sheath size and balloon diameter were 12 mm (10–14 mm) and 14 mm (12–25 mm), respectively. We achieved an immediate success rate of 94.6% with only three cases recording major complications in the form of migration of stent, infective endarteritis, and stent fracture. At 1-year follow-up, no complications were noted in the computed tomography scans. Conclusion Stent implantation is a good choice for the treatment of CoA in adolescents and adults. It is associated with a low-residual gradient and a low rate of restenosis, both immediately and at mid-term follow-up. It has a relatively low incidence of complications.
