- Right heart dominance: the posterior portion of the interventricular septum is supplied by the posterior descending branch of the right coronary artery.
- Left heart dominance: the entire septum is supplied by branches of the left anterior descending artery; an obstruction in that vessel may lead to loss of the entire septum, an often fatal event. The posterior descending artery is derived from a branch of the circumflex artery instead of from the RCA.
