Implantation of Covered Stent for Coarctation of the Aorta and Secondary Hypertension in Adolescents—Case Report

Abstract

Introduction: Coarctation of the aorta represents a narrowing of the thoracic aorta. Hypertensive patients with blood pressure differences ≥20 millimetres of mercury have an indication for surgical or interventional treatment. Implantation of a covered stent became the preferred therapy for the management of this pathology in adolescents/adults. Case report: We report the case of a 14-year-old male sportsman, who presented in the emergency room with headache, dizziness, and tinnitus. The clinical exam revealed blood pressure differences between the upper and lower limbs of up to 50 mmHg. Based on the clinical and paraclinical data, we established the diagnosis of coarctation of the aorta and severe secondary arterial hypertension. The case was discussed by a multidisciplinary team and accepted for covered stent implantation. The 24 h blood pressure Holter monitoring after the procedure indicated the persistence of stage I arterial hypertension. Conclusions: Coarctation of the aorta is a congenital cardiovascular anomaly with high morbidity and mortality rates. Arterial hypertension, heart failure, and aortic dissection are complications of this pathology, some of them being sometimes direct consequences of secondary hypertension. Periodic cardiology follow up after the procedure is mandatory to assess the hemodynamic response, to identify potential complications, and to stratify the cardiovascular risk.
