The circumflex artery curves to the left around the heart within the coronary sulcus, giving rise to one or more left marginal arteries (also called obtuse marginal branches) as it curves toward the posterior surface of the heart. It helps form the posterior left ventricular branch or posterolateral artery.
It is called the 'obtuse' margin because of the obtuse angle (>90 degrees) created between the anterior part of the heart and the left side, which is formed from the rounded lateral wall of the left ventricle. Within this margin can be found the obtuse marginal artery, which is the a branch of the left circumflex artery.

Illustration of a typical coronary artery bypass surgery. A vein from the leg is removed and grafted to the coronary artery to bypass a blockage at LAD. Coronary artery bypass surgery during mobilization (freeing) of the right coronary artery from its surrounding adipose tissue (yellow).
If the posterior descending artery is supplied by the circumflex artery (CX), a branch of the left artery, then the coronary circulation can be classified as "left-dominant." If the posterior descending artery is supplied by both the right coronary artery and the circumflex artery, then the coronary circulation can be classified as "co-dominant."
