Right Coronary Artery Originating From Mid Left Anterior Descending Artery: A Rare Variant of Anomalous Right Coronary Artery Detected on CT Coronary Angiography.

Background: A single coronary artery (SCA) is a rare anomaly encountered using conventional angiography. right (RCA) originating from left anterior descending (LAD) subtype of SCA. Only few cases are described in published literature. Case presentation: We this 55-year-old male who presented with angina pectoris. The anomalous RCA was suspected by angiogram and confirmed computed tomography (CT) Using CT, we demonstrated the course abnormal vessel its relation to main vessel. also detected presence plaque, which caused luminal stenosis proximal LAD, may cause global ischaemia. Conclusion: concluded that although angiography an important diagnostic method, new non-invasive methods such as CT can be better screening tool detect characterise anomalies.
