Objective: To compare aortic vessel measurements obtained by CT and DA in patients diagnosed with aortic coarctation treated at a pediatric hospital in Peru. Materials and methods: An observational, descriptive, and cross-sectional study was conducted through a retrospective review of medical records of patients under 18 years of age diagnosed with CoA and treated between 2013 and 2023. Epidemiological, clinical, and aortic vessel measurement variables were collected, and diameters obtained by both techniques were compared. Results: Of the 42 patients included in the study, 64.3% were male, with a median age of 8.5 years (IQR: 3–13.25). The postductal form was the most frequent (52,3%). Therapeutic catheterization was the predominant treatment (64%). In the comparison of aortic measurements, DA showed slightly higher values in the aortic arch, isthmus, and coarctation site, although no statistically significant differences were found compared to CT (p>0.05). Conclusion: CT and DA showed similar measurements in the evaluation of aortic anatomy in pediatric patients with CoAo. In Peru, where access to invasive procedures is centralized, CT is a highly valuable noninvasive diagnostic tool for anatomical characterization and follow-up, particularly when immediate therapeutic intervention is not required.
