Patients with ostial Cx stenosis or total occlusions of the Cx or RCA were excluded. Traditionally, surgeons have performed open heart surgery, often a coronary artery bypass graft (CABG), to create a detour around the blockage and restore blood flow. But stents may not provide a lasting treatment and the original symptoms can come back within a year. 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 (OM)) as it curves toward the posterior surface of the heart. (This is called a dissection. ) After a normal head CT and discussion with the on-call interventional cardiologist, the patient is taken for percutaneous coronary intervention (PCI) where a 99% occlusion of the proximal left circumflex (LCX) is found and thought to be the culprit lesion (Figure 2). The obtuse marginal (OM) arteries sometimes referred to as lateral branches are branch coronary arteries that come off the circumflex artery.There can be one or more obtuse marginal arteries.

This study compared people who had heart artery blockages treated with stents and medications to those treated with just medications. The circumflex artery itself divides into smaller arterial systems. Current revascularization guidelines recommend a "heart team" discussion in patients with stable coronary artery disease and proximal LAD disease and confer a class I indication level of evidence A to both, percutaneous and surgical, treatment strategies. The most common way to do that is with a surgery called " carotid endarterectomy .".

It typically traverses along the left margin of heart towards the apex. Percutaneous coronary intervention, also . However, in the presence of severe stenosis, there is limited anterograde flow, which makes it challenging to visualize the course of the stenotic artery, and it can be assumed to be a chronic total occlusion (CTO). The branch angle between left anterior descending artery (LAD) and LCX was shallow, therefore stent implantation seemed at risk of "carina shift" of plaque to the LAD ostium as well as higher . The circumflex artery, fully titled as the circumflex branch of the left coronary artery, is an artery that branches off from the left coronary artery to supply portions of the heart with oxygenated blood.
