Coronary artery anomalies (CAAs) are known to be anatomical aberrations in the origin and structure. Due to the diverse anatomical variants, surgeons and angiographers have struggled when faced with patients who have CAA. To frame the complicated issues surrounding CAA, we present a case of a young patient found to have two CAAs, concurrently on coronary computed tomography angiography (CCTA), while in the emergency room being evaluated for chest pain. Patient was medically observed without any invasive procedure since he was deemed to have low cardiovascular risk. Subsequently, literature on prevalence, as well as high risk findings are reviewed. Further studies to evaluate pharmacological, angiographic, and surgical interventions may have additional benefit for both patients and practitioners. Our aim is to help shed the light on difficulties cardiologists are facing during angiography. Additionally, our paper offers some guidance for how to evaluate and follow patients with similar findings into the future.
