| Abstract: | Aortic arch anomalies underlie numerous congenital disorders. Effectively diagnosing and treating them requires close understanding of cardiovascular embryology. As our Center serves the entire pediatric population of our country, we performed a comprehensive retrospective analysis of all aortic arch anomalies diagnosed at our Center over the past 20 years. We analyzed 40 children with aortic arch anomalies, distinguishing two defect types: Group 1 displayed ring‐forming anomalies, and Group 2 other types of aortic arch anomalies that did not form a vascular ring. We performed detailed morphological analyses using echocardiography, angiography, computed tomography, or magnetic resonance imaging and generated a catalog of all aortic arch anomalies present. Group 1 was represented by 25 patients; 40% with persistent both aortic arches, and 60% with various forms of right aortic arch and an incomplete left aortic arch. Group 2 was represented by 15 patients with complex heart defects. On the basis of our dataset, the incidence of all aortic arch anomalies was 0.033%, and of ring‐forming pathologies 0.021%. Although aortic arch anomalies are rare, it is important to diagnose them correctly. It is critical to distinguish ring‐forming types. Although in complex defects the aortic arch anomaly represents only an additive diagnosis, its correct definition could be crucial for further management. Cumulatively, this unique, long‐term study provides a systematic patient registry and offers critical epidemiological data to aid the study of rare congenital cardiovascular defects. Clin.
