What is the function of the anterior interventricular artery?
It provides the major blood supply to the interventricular septum, and thus bundle branches of the conducting system. Hence, blockage of this artery due to coronary artery disease can lead to impairment or death (infarction) of the conducting system.
What is the function of interventricular sulcus?
The interventricular sulcus is a superficial groove or depression between the ventricles. It is of importance because this is where some of the large coronary arteries and veins run. Those vessels carry blood to and from the walls of the heart.
What does the anterior interventricular branch supply?
The anterior interventricular septal branches supply the anterior two thirds of the interventricular septum and the atrioventricular bundle. The inferior interventricular septal branches supply the distal third of the inferior interventricular septum.

Which vessel supplies blood to both ventricles and the anterior interventricular septum?
The LAD provides blood to the anterior ventricular septum and the greater portion of the anterior portion of the left ventricle. The LCx supplies blood to the lateral wall of the left ventricle and sometimes to the posterior inferior aspect of the heart when there is left heart dominance.

Which side of the sulcus is the AIV?
Within the anterior interventricular sulcus, the AIV is accompanied on the left side by the anterior interventricular vein. This represents the first part of the great cardiac vein.
Which branch of the ventricular system supplies the left side of the conus arteriosus?
The conal branch is a small branch which supplies the left aspect of the conus arteriosus, anastomosing with the larger conus artery of the right coronary artery.

What is the AIV branch of the heart?
Left anterior descending artery (LAD) The left anterior descending artery, preferably known as the anterior interventricular artery (AIV), is the continuing branch of the left coronary artery. It is located subepicardially within the anterior and inferior interventricular sulci of the heart.
