Twin Circumflex Arteries: A rare Coronary Artery Anomaly

Accurate recognition and documentation of coronary artery anomalies and their course at the time of coronary angiography is essential to determine the significance of such findings and to avoid therapeutic complications. The identification of this anomaly demands a high level of anticipation during the performance of selective coronary angiography to ensure that an adequate study is obtained. Failure to recognize and properly demonstrate the anomaly may result in improper therapeutic decisions that may be hazardous to the patients. Special surgical considerations must be made when performing the valvular replacement or coronary artery bypass grafting, if desired, in such patients.
