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 PDA supplies the posterior third of the interventricular septum. The remaining anterior two-thirds is supplied by the left anterior descending artery, which is a branch of left coronary artery. It is typically a branch of the right coronary artery (70%, known as right dominance).
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 ]
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."
