Your circumflex artery is a type of cardiac blood vessel that’s part of your circulatory system. This network of blood vessels circulates blood to your heart and the rest of your body. The functions of the circumflex artery vary depending on a person’s unique anatomy.

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.

2022年12月5日 · The circumflex artery, sometimes called the left circumflex artery (LCX), is the posterior division of the left coronary artery. Located in the coronary sinus between the left atrium and ventricle , it wraps around the left cardiac margin crossing from the sternocostal (anterior) to the diaphragmatic (inferior) surface of the heart .

The left anterior descending artery branches off the left coronary artery and supplies blood to the front of the left side of the heart. The circumflex artery branches off the left coronary artery and encircles the heart muscle.

2024年2月6日 · The circumflex artery (Cx) is one of the two major coronary arteries that arise from the bifurcation of the left main coronary artery (the other branch being the left anterior descending (LAD) artery).

The Circumflex (Cx) coronary artery is a branch of the left main coronary artery after the latter runs it's course in between the aorta and the main pulmonary artery,. The Cx travels in the left atrio-ventricular groove that separates the left atrium from the left ventricle.

The circumflex artery travels along the anterior aspect of the heart, within the atrioventricular groove. Here, the left atrial appendage sits over the vessel anteriorly. As the name suggests, the circumflex branch curves to the left and becomes posterior, still within the atrioventricular groove.

2023年7月24日 · The circumflex artery is responsible for blood supply to the left atrium and the posterior-lateral aspect of the left ventricle while the LAD supplies blood to the anterior portion of the left ventricle.

The circumflex artery branches off of the left coronary artery and supplies most of the left atrium: the posterior and lateral free walls of the left ventricle, and part of the anterior papillary muscle.

The prevalence of the left circumflex coronary artery (LCx) as the culprit vessel in ST-segment-elevation myocardial infarction (STEMI) is reportedly lowest among that of the 3 main epicardial arteries, and has not been described for non-STEMI (NSTEMI) and stable angina pectoris.
