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.
In the other 20%, of cases (left dominant or codominant), the PDA arises from the left circumflex artery or is supplied by both the right coronary artery and the left circumflex. [8] The PDA supplies the inferior wall, ventricular septum, and the posteromedial papillary muscle. [citation needed] The RCA also supplies the SA nodal artery in 60% ...
The right coronary artery (RCA) originates within the right cusp of the aortic valve. It travels down the right coronary sulcus , towards the crux of the heart . The RCA primarily branches into the right marginal arteries , and, in 67% of individuals, gives place to the posterior descending artery. [ 4 ]
RCA = right coronary AB = atrial branches SANB = sinuatrial nodal RMA = right marginal LCA = left coronary CB = circumflex branch LAD/AIB = anterior interventricular LMA = left marginal PIA/PDA = posterior descending MARG = left marginal AVN = atrioventricular nodal VEINS: SCV = small cardiac ACV = anterior cardiac AIV/GCV = great cardiac MCV ...
The artery that supplies the posterior third of the interventricular septum – the posterior descending artery (PDA) [3] determines the coronary dominance. [ 4 ] If the posterior descending artery is supplied by the right coronary artery (RCA), then the coronary circulation can be classified as "right-dominant."
The circumflex branch of left coronary artery (also known as the left circumflex artery or circumflex artery [citation needed]) is a branch of the left coronary artery.It winds around the left side of the heart along the atrioventricular groove (coronary sulcus).

Curved planar reformatted image of sinoatrial nodal artery originating from proximal left circumflex artery. Variant anatomy. The sinoatrial nodal artery, sinoatrial nodal artery or sinoatrial artery is an artery of the heart which supplies the sinoatrial node, the natural pacemaker center of the heart.
