Intra-Atrial Course of Right Coronary Artery: Rare Anatomical Variants Are Becoming More Common with Modern Cardiac CT Scanners

Coronary artery anomalies, which range from benign variations to potentially malignant conditions, are increasingly being identified due to advancements in coronary computed tomography (CT) imaging. This case report highlights a 51-year-old male patient who was diagnosed with an intra-atrial course of the right coronary artery while undergoing evaluation for symptoms suggestive of angina. The detection of this rare anatomical variant was facilitated by modern cardiac CT technology. Following diagnosis, the patient was thoroughly reassured and educated about his condition. He was advised to avoid excessive physical exertion and was given guidance on lifestyle modifications to manage his symptoms effectively. It is crucial for healthcare providers to be aware of such anomalies, especially when planning surgical interventions or invasive procedures, to prevent potentially catastrophic outcomes.
