The inferior interventricular artery (also known as the posterior interventricular artery or posterior descending artery, PDA) is an artery that extends along the inferior interventricular sulcus. The artery supplies the posterior third of the interventricular septum through posterior septal perforating arteries.
It supplies the diaphragmatic portion of the left ventricle.
The inferior interventricular artery can anastomose with the anterior interventricular artery, a branch of the left anterior descending (LAD), over the apex of the heart. It can also anastomose with the LAD through each vessel's respective septal perforators.
The vessel that supplies this artery establishes the coronary artery dominance of the heart. In a right-dominant system (89.1%), the right coronary artery supplies it. In a left-dominant system (8.4%), the left circumflex supplies it.
