Septals

Septal Arteries from the LAD
Normal axial CT of the septal coronary arteries showing their origin from the LAD. They quickly enter the myocardium and are small and are therefore usually impossible to visualise

Obtuse Marginal Arteries off the Circumflex ? 3D CT
Reconstruction of the CTA of the circumflex coronary artery showing the obtuse marginals supplying the posterolateral wall of the left ventricle (LV)
