What vessels are situated in sulcus Interventricularis posterior?
The other groove is the anterior interventricular sulcus, situated on the sternocostal surface of the heart, close to its left margin. In it runs the posterior interventricular artery and middle cardiac vein….

What structures does the posterior interventricular artery supply?
The posterior interventricular artery runs alongside the middle cardiac vein down the posterior interventricular sulcus and supplies the AV node, the posterior 1/3 of the interventricular septum, the posterior 2/3 walls of the ventricles, and is the only vessel supplying the posteromedial papillary muscle.
Is the posterior interventricular artery the same as the posterior descending artery?
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.
What happens when RCA is blocked?
If the blockage occurs more slowly, the heart muscle may develop small collateral blood vessels (or detours) for other coronary arteries to reroute the blood flow, and angina occurs.
What is the function of the posterior interventricular artery?
The origin of the posterior interventricular artery accounts for the termed dominance of the heart. The main function of the posterior interventricular artery is to supply a small posterior aspect of the interventricular septum [7] and the posterior aspect of the right ventricle [6].
What is the posterior groove between the ventricles called?
role in cardiovascular system surface, a groove called the posterior longitudinal sulcus marks the division between the right and left ventricles; it contains another branch of a coronary artery.
Which is true of the posterior interventricular artery?
The posterior interventricular artery (posterior descending artery – PDA) is a branch of the right coronary artery. This artery runs in the posterior (inferior) interventricular sulcus. Its main function is to supply the diaphragmatic (inferior) surface of the myocardium and interventricular sulcus of the heart.
What is the function of posterior interventricular artery?
What is the right posterior descending artery?
The marginal branch of the right coronary artery provides blood supply to the lateral portion of the right ventricle. The posterior descending artery branch supplies blood to the inferior aspect of the heart. The LMCA supplies blood to the left side of the heart.
Where does posterior interventricular artery come from?
| Posterior interventricular artery | |
|---|---|
| Source | right coronary artery |
| Vein | middle cardiac vein, posterior interventricular vein |
| Supplies | ventricles interventricular septum |

Where does the posterior interventricular sulcus begin?
Also called posterior interventricular artery. It originates in the circumflex artery in 15% of the patients and runs through the posterior interventricular sulcus ending, in most cases, in the distal third of the inferior wall. Up to one-third of patients have a trifurcated left main coronary artery.
How many people have the ramus intermedius artery?
The ramus intermedius is a variant coronary artery resulting from trifurcation of the left main coronary artery 1. It is present in ~20% (range 15-30%) 2-3 of the population. It can have a course similar to the obtuse marginal branches of the left circumflex artery or the diagonal branches…
Its main function is to supply the diaphragmatic (inferior) surface of the myocardium and interventricular sulcus of the heart . The posterior interventricular artery can arise from either the left or right coronary artery. The “dominant” coronary artery is the one that gives rise to PDA.
