Left Main and Right Coronary Artery Arising from Single Coronary Trunk: A Very Rare Cardiac Anomaly

Aim: Single coronary artery is a rare anomaly. Patients may present with syncope, angina or rarely sudden cardiac death.

Presentation of Case: Patient presented with dyspnea on exertion for one year. On 2D Echo patient had small restrictive VSD. On coronary angiography single coronary artery from right cusp was seen. On CT angiography anomalous origin was confirmed. There was no malignant course of coronary artery.

Discussion: Anomalous origin of coronary arteries are rare cardiac anomalies. It can present as syncope, angina, or sudden cardiac death especially in patients with malignant course of coronary artery passing between aorta and pulmonary artery. Hence CT coronary angiography is useful to rule out the malignant course. In our patient, there was no malignant course hence managed conservatively.

Conclusion: Anomalous origin of coronary artery is a rare anomaly and requires tailored treatment according to type and course of artery.
