Coronary Anomalies: Understanding of Normal Coronary Artery Development for Insight in Treatment of Coronary Artery Disease.

Coronary artery anomalies (CAA) are rare congenital abnormalities with incidence of about 1% in the general population.2Unfortunately, despite the low incidence, CAA can cause sudden cardiac death. Identifying the course of the artery is critical for appropriate management. We present a rare case of the left coronary artery arising from the right coronary ostium with special emphasis on normal coronary artery development as possible insight for treatment of diseased heart.
