Frequently Asked Questions

What is the posterolateral artery?

The posterolateral artery is a coronary artery that branches from either the right coronary artery or the circumflex artery and is involved in supplying blood to the posterior and lateral walls of the left ventricle.

Where is the posterolateral artery located?

The posterolateral artery is located on the posterior surface of the heart, running in the atrioventricular groove or along the posterior wall of the left ventricle, with its origin depending on coronary dominance.

What is the function of the posterolateral artery?

The posterolateral artery is involved in supplying oxygenated blood to the posterior and lateral walls of the left ventricle, as well as potentially to the posteromedial papillary muscle and adjacent myocardium.

What conditions may be associated with the posterolateral artery?

Myocardial infarction involving the posterior or lateral left ventricle, coronary artery disease, or ischemia detected on cardiac stress testing may be associated with stenosis or occlusion of the posterolateral artery.

How is the posterolateral artery examined?

The posterolateral artery may be assessed through coronary angiography, CT coronary angiography, cardiac MRI, or nuclear medicine perfusion studies evaluating posterior and lateral wall myocardial blood flow.
