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. The PDA ...
The posterior interventricular artery, a branch of right coronary artery, supplies the posterior 1/3 of the interventricular septum. The remaining anterior 2/3 is supplied by the anterior interventricular artery, which is a septal branch of the left anterior descending artery, which is a branch of left coronary artery. [2]
On the posterior surface of the heart, the right coronary artery gives rise to the posterior interventricular artery, also known as the posterior descending artery. It runs along the posterior portion of the interventricular sulcus toward the apex of the heart, giving rise to branches that supply the interventricular septum and portions of both ...
The crux cordis or crux of the heart (from Latin "crux" meaning "cross") is the area on the lower back side of the heart where the coronary sulcus (the groove separating the atria from the ventricles) and the posterior interventricular sulcus (the groove separating the left from the right ventricle) meet. [1]
The right marginal arteries perfuse the right ventricle and the posterior descending artery perfuses the left ventricular posterior and inferior walls. There is also the conus artery , which is only present in about 45 percent of the human population, and which provides collateral blood flow to the heart when the left anterior descending artery ...
The circumflex artery ends at the point where it joins to form to the posterior interventricular artery in 15% of all cases, which lies in the posterior interventricular sulcus. In the other 85% of all cases the posterior interventricular artery comes out of the right coronary artery. [3]

They can be known as subsinosal interventricular groove or paraconal interventricular groove respectively. It is located on the diaphragmatic surface of the heart [1] [2] near the right margin. [2] It extends between the coronary sulcus and the (notch of [2]) apex of the heart. It contains the posterior interventricular artery and middle ...
