320-slice Computed Tomography Angiography Imaging Findings and Follow-up in A Patient with Aortic Coarctation Misdiagnosed as Hypertension: A Case Report and Literature Review.

In this case, we report a simple coarctation of the aortic isthmus (CoA) in a patient without intracardiac abnormalities or patent ductus arteriosus, who was misdiagnosed as essential hypertension for over 20 years. The patient underwent X-rays, echocardiography, and 320-slice CT angiography (CTA). Among them, CTA comprehensively showed the diameter of the aortic coarctation, the anatomy and morphology of the heart and aortic arch, and the collateral circulation before surgery. It also accurately evaluated the postoperative status of the bypass vessel. This article highlights the excellent performance of 320-slice CTA in the diagnosis, surgical planning, and follow-up in CoA. Moreover, when adolescents suffer from refractory hypertension, the possibility of organic cardiovascular disease should be considered.
