Analysis of morphometric details of aortic coarctation and collateral circulation using computed tomography (CT) and its impact on clinical symptoms is a perspective which is missing in the published literature.

To perform CT-based qualitative and quantitative evaluation of aortic coarctation and collateral circulation with reference to clinical symptoms.

The study comprised 2022 patients who underwent CT angiography. If aortic coarctation was seen, the patients underwent evaluation of its anatomy and associated clinical symptoms.

Aortic coarctation was found in 33 patients. Follow-up (median 2476 days; range 1692–3543) was performed in 31 (94%) individuals. In this group (median age 42 years; range 30–52.5 years), median stenosis at the site of coarctation was 70% (range 58–85%) of the lumen area, with 17 (55%) patients presenting with significant (≥70 …
