From Chest Pain to Recovery: A Rare Case of Anomalous origin of the circumflex artery from the pulmonary artery in a Child and the Role of Timely Surgical Intervention

This report highlights the diagnostic challenges and successful surgical management in a symptomatic pediatric case with anomalous origin of the circumflex artery from the pulmonary artery. A 4-year-old boy presented emergently with dyspnea and substernal pain. Coronary angiography identified the circumflex artery originating anomalously from the right pulmonary artery. Emergency surgical reimplantation to the aorta was performed, with subsequent normalization of cardiac function (EF 67 % at 3-month follow-up). Although exceptionally rare, anomalous origin of the circumflex artery from the pulmonary artery requires high clinical suspicion in pediatric patients with ischemic symptoms. Early anatomical correction yields excellent outcomes, as demonstrated in this case.
