Septal branches of the left anterior descending artery

Last revised by Craig Hacking on 9 Feb 2021

The septal branches of the left anterior descending artery supply blood flow to the interventricular septum of the heart.

Origin

These are right-sided branches (on axial CTCA) from the left anterior descending artery.

Supply

They provide the main blood supply to the anterior interventricular septum. A smaller posterior section is also supplied from the posterior descending artery instead (see coronary arterial dominance).
