Anomalous Right Coronary Artery: A Rare Cause of Recurrent Syncopal Attacks

Anomalous origin of the coronary artery is a rare anomaly and does not generally lead to myocardial infarction and ventricular tachycardia. We report an uncommon case of anomalous origin of the right coronary artery originating from the left sinus of Valsalva with ventricular tachycardia and myocardial ischemia. A 42-year-old male was transferred from an external facility due to syncope and documented episodes of ventricular tachycardia preceding syncope. MPS showed small ischemic area in the inferior wall. Coronary CT angiography confirmed that RCA was originating from the left coronary aortic sinus with a separate ostium from the LMCA and coursing between the aorta and the pulmonary trunk. After consulting with cardiothoracic surgeons, the decision to perform corrective surgery was made. A successful correction surgery was performed by the surgeons, and the patient was asymptomatic after surgery
