Abstract: Background: Coarctation of the aorta (CoA) is a well-known congenital heart disease, which is often associated with other cardiac and vascular anomalies, most frequently a bicuspid aortic valve. Aortic coarctation is an unusual cause of hypertension during pregnancy, and its management is not clarified. Case summary: We report a case of a 24-year-old pregnant woman with long-standing hypertension, who presented at the end of the first trimester with severe refractory hypertension. The diagnostic investigation culminated in the diagnosis of a CoA. Facing risks for pursuing pregnancy such as aortic complications, hypertensive disorders, and foetal adverse outcomes, aside from limited therapeutic options and having in mind the relatively early stage in pregnancy, it was decided by multidisciplinary team and the patient for pregnancy interruption. After that, the patient was treated by percutaneous dilatation of aortic coarctation with stent implantation, with good results. Recently, the patient was able to carry out a newly full-term pregnancy without major incidents. Conclusion: Coarctation of the aorta should be considered in pregnant women with refractory hypertension. It is associated with considerable risks to the mother and to the foetus. In cases presenting with refractory severe hypertension, termination of pregnancy needs to be considered, especially in first-trimester pregnancies.This case also highlights the importance of investigating secondary causes of hypertension in young people, as these can often be treated, averting potentially severe complications.
