Posterior LV Branches
The coronary angiogram of the RCA has been shown above but is shown again relevant to this discussion. It is taken in the left anterior oblique projection showing the posterior left ventricular branches taking origin just after the AV nodal artery (AVn). There are two large posterior LV branches that course inferiorly on the posterior aspect of the left ventricle.
