Clinical features and prognosis in patients with coronary anomalies: the experiences and follow-up results of a single center.

Introduction: Coronary anomalies (CAs) are rare congenital abnormalities often found incidentally on conventional coronary angiography (CCA), coronary computed tomographic angiography (CCTA), or autopsy. Aim: This study aimed to investigate the prevalence of origin and termination coronary artery anomalies via CCTA, and to evaluate outcomes over an 8-year follow-up. Material and methods: To diagnose CAs, the CCTA data of 3017 consecutive patients who had undergone CCTA between January 2015 and January 2023 were analyzed retrospectively and followed up. Results: Among the 3017 patients, 60 (2%) had coronary anomalies. Fifty-seven (95%) patients had origin and distribution anomalies, and 3 (5%) patients had a coronary artery fistula. The most common origin anomaly (13, 21.7%) was an anomalous origin of the right coronary artery (RCA), and the second one was (12, 20%) congenital atresia of the left main artery. It was also found that among anomalies, the most common (16, 26.6%) was the anomaly of course. Statistical analysis showed that the presence of CAs did not affect the development of major cardiovascular events (MACE) or mortality ( Conclusions: In this single-center study, the prevalence of CAs (2%) and the results of MACE and mortality were similar to those reported in the literature.
