Introduction

Until recent years, coronary venous system imaging was overshadowed by coronary artery imaging. However, in recent times, the significance of coronary venous system imaging has risen markedly, particularly due to its pivotal role in diverse interventional cardiology procedures. These interventions encompass a spectrum of tasks, including left ventricular pacing, mapping and ablation of arrhythmias, and retrograde cardioplegia. These procedures are facilitated by utilizing the potential of the coronary sinus (CS). As a result, comprehending the anatomy and anomalies of the CS holds paramount importance, and coronary computed tomography (CT) angiography has proven invaluable for achieving this objective.

In this case report, we present an extraordinary cardiac venous anomaly: a bridging vein connecting the left atrium to the CS with non-specific chest pain. We believe that this case serves as an illustrative example for understanding rarely observed cardiac venous vascular anomalies, while also making a valuable contribution to the existing literature through the utilization of clear and direct coronary CT angiography images.
