| Anatomical terminology | |
The circumflex branch of left coronary artery (also known as the left circumflex artery or circumflex artery) is a branch of the left coronary artery. It winds around the left side of the heart along the atrioventricular groove (coronary sulcus). It supplies the posterolateral portion of the left ventricle.[1]
In a minority of individuals, the left circumflex artery gives rise to the posterior interventricular artery, in which cases such a heart is deemed left dominant.[1]
