Intra-Atrial Right Coronary Artery: A Condition Revealed by Coronary CT Scan

Coronary artery anomalies are rare and may involve the coronary origin, course, or termination. Most are benign; however, some can lead to myocardial damage, sudden death, or potential hazards during interventional or surgical procedures.

The present is a brief review about this rare congenital anomaly.
