where does the posterior descending artery branch from
The posterior descending artery, which is also known as the posterior inter-ventricular artery, is a branch of one of the heart's main arteries. In most people, the posterior descending artery branches away from the right coronary artery, which is called right coronary artery dominance. In left coronary artery dominance, the posterior descending artery branches away from the left circumflex artery.
