Abstract


Anomalies involving the origin of the coronary arteries are extremely rare, with the left main artery coronary artery (LMCA) originating from the right coronary sinus (RCS) one of its rarest forms. Anomalous origin of left main from right coronary sinus poses a high risk of sudden cardiac arrest. In our report, we shed light on the case of a 43-year-old female who suffered a witnessed cardiac arrest due to underlying anomalous origin of the left main artery from right coronary sinus. The patient was initially pronounced dead until return of spontaneous rhythm with concomitant myocardial infarction led to the diagnosis of anomalous coronary artery. This case stresses important points to consider when dealing with the acute management and chronic treatment plan for this subset of high-risk patients. We also consider the utility of mechanical circulatory support in management of this condition.
