Classification Dilemma between Right Single Coronary Artery and Agenesis of Left Main Coronary Artery: A Rare Coronary Anomaly [Tek sağ koroner arter ve sol ana koroner arter agenezi arasında sınıflamada çelişki: Nadir bir koroner anomali]

Abstract

The term “coronary artery anomaly” encompasses a broad spectrum of congenital abnormalities that affect the origin, path, and structure of the epicardial coronary arteries. With an estimated occurrence rate of 0.024 to 0.066% in the general population, single coronary artery (SCA) is an uncommon congenital anomaly characterized by the presence of a solitary coronary artery originating from a single coronary ostium, providing blood supply to the entire heart.[1-3] While the affected cases may be asymptomatic, they also are likely to be admitted with a variety of symptomology, including typical or atypical anginal chest pain, ventricular arrhythmias, syncope, acute coronary syndrome, or sudden cardiac death.[2] Herein, we presented a unique case of right SCA that does not fit the current classification system.
