A very rare coronary artery anomaly: Twin circumflex arteries associated with acute coronary syndrome - two cases report

Abstract

Circumflex coronary artery anomalies are the most common type so far observed. However, a dual origin of the circumflex is an extremely rare anomaly. We describe two different patients admitted to our clinic with acute coronary syndrome at the same day. Angiography revealed twin circumflex arteries: one from the left main artery and the other from the proximal right coronary artery.
