ABSTRACT = {<b>Background:</b> There has been an increasing number of studies documenting the application of the right axillary thoracotomy (RAT) approach for the repair of congenital heart diseases. However, no research has reported the RAT approach in repairing the anomalous aortic origin of a coronary artery (AAOCA). This study aims to investigate the feasibility and safety of the RAT approach for repairing AAOCA in children. <b>Methods:</b> We performed a retrospective study at the Children’s Hospital of Chongqing Medical University between January 2024 and October 2025 to investigate the clinical outcomes of the RAT approach for repairing AAOCA in children. <b>Results:</b> A total of twelve patients with AAOCA were operated on via a RAT approach. Conventional unroofing was performed in eight cases, and a modified unroofing procedure was performed in four cases. Simultaneous repair of associated cardiac defects was conducted in eight cases. Postoperative pneumonia occurred in one patient. There were no early deaths during the hospitalization. The postoperative ostial diameter was significantly larger than the preoperative diameter (<i>p</i> = 0.0005). No patients were lost to follow-up, and aortic valve insufficiency was not observed during the follow-up. There were no late deaths reported following discharge, and ischemic signs were also not documented. <b>Conclusions:</b> Surgical repair via the RAT approach may serve as a safe and effective alternative for children with AAOCA. However, surgical strategies should be carefully determined based on preoperative assessment of the anomalous coronary arteries.},
