In the coronary circulation, the posterior interventricular artery (PIV, PIA, or PIVA), most often called the posterior descending artery (PDA), is an artery running in the posterior interventricular sulcus to the apex of the heart where it meets with the anterior interventricular artery or also known as Left Anterior
What is the function of the interventricular sulcus?
role in cardiovascular system
Shallow grooves called the interventricular sulci, containing blood vessels, mark the separation between ventricles on the front and back surfaces of the heart.
What is located in the posterior coronary sulcus?
Coronary Sinus. The coronary sinus, the length of which varies from 15 to 65 mm, is found at the posterior part of the coronary sulcus on the diaphragmatic or posterior surface of the heart and is the principal collector of the venous blood of the heart.
What structures are found in the interventricular sulci?
The anterior interventricular branch of the left coronary artery runs in the sulcus along with the great cardiac vein.

What travels with the posterior interventricular 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. The posterior interventricular artery can arise from either the left or right coronary artery.
Which of the following accompanies the anterior interventricular artery?
The great cardiac vein accompanies the anterior interventricular artery; the middle cardiac vein accompanies the posterior interventricular artery and the small cardiac vein accompanies the marginal artery.
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 function of the anterior interventricular artery?
The artery gives off conal, anterior ventricular and interventricular septal branches. They contribute mainly to the blood supply of the anterior surface of the left ventricle and the distal two thirds of the interventricular septum, both anterior and inferior.
What is the atrioventricular sulcus?
Anatomical terminology. The coronary sulcus (also called coronary groove, auriculoventricular groove, atrioventricular groove, AV groove) is a groove on the surface of the heart that separates the atria from the ventricles.
What coronary vein lies in the anterior interventricular sulcus?
The great cardiac vein (GCV) runs in the anterior interventricular groove and drains the anterior aspect of the heart where it is the venous complement of the left anterior descending artery. It is the main tributary of the coronary sinus.
Where does the posterior interventricular artery come from?
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.
Is the posterior interventricular artery the same as the posterior descending artery?
The posterior descending artery (PDA) is also known as the posterior interventricular artery because it runs along the posterior interventricular sulcus to the apex of the heart. It is at the apex where it meets the left anterior descending artery that is traveling along the anterior surface of the heart.
