In the coronary circulation, the posterior descending artery (PDA), also called the posterior interventricular artery (PIV, PIA, or PIVA), is an artery running in the posterior interventricular sulcus to the apex of the heart where it meets with the left anterior descending artery also known as the anterior interventricular artery.
Posterior descending artery; Ramus or intermediate artery; Right coronary artery. Right marginal artery; Posterior descending artery; The left coronary artery arises from the aorta within the left cusp of the aortic valve and feeds blood to the left side of the heart. It branches into two arteries, the left anterior descending and the left ...
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
The posterior interventricular sulcus or posterior longitudinal sulcus is one of the two grooves separating the ventricles of the heart (the other being the anterior interventricular sulcus). They can be known as subsinosal interventricular groove or paraconal interventricular groove respectively.
The middle cardiac vein commences at the apex of the heart. It passes posteriorly along the inferior interventricular sulcus to end at the coronary sinus near the sinus' termination. [ 1 ]
[1] [2] It often anastomoses with the nearby parallel posterior interventricular artery, which itself is usually a continuation of the right coronary artery. [ 3 ] Variation

The atrioventricular nodal branch sees significant variation in origin: proximal posterolateral branch from the right coronary artery in around 77%. [1]distal posterolateral branch from the right coronary artery in around 2%.
