What are the diagonal arteries?
Diagonal branches of the left anterior descending coronary artery supply blood flow to the anterior and anterolateral walls of the left ventricle. There are usually denoted as D1, D2, D3, etc. There are termed “diagonal” due to them branching from their parent vessel at acute angles.
How many diagonal branches are there in LAD?
The Left Main coronary artery typically bifurcates into two branches, the left anterior descending artery (LAD) and the circumflex artery (Cx). Occasionally, a third branch called Ramus Intermedius may arise between the LAD and the Cx.
Where does the anterior interventricular artery branch from?
The left anterior descending artery (also LAD, anterior interventricular branch of left coronary artery, or anterior descending branch) is a branch of the left coronary artery.
What is the anterior interventricular branch?
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. Therefore, it is colloquially known as the widow maker artery.
Where is the diagonal branch?
left coronary artery
The diagonal branch is one of the terminal branches of the left coronary artery, as well as the circumflex and anterior interventricular branches, when it splits into three or four branches.
What branches into the anterior interventricular artery and the marginal 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. Anterior cardiac veins seen on the anterior wall of the right ventricle drain directly into the right atrium.
Which of the following accompanies the anterior interventricular artery?
great cardiac vein
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. Anterior cardiac veins seen on the anterior wall of the right ventricle drain directly into the right atrium.
What does the anterior interventricular artery do?
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.
Which of the following accompanies anterior interventricular artery?
The anterior interventricular artery supplies the: left ventricle. right ventricle – small section of outflow tract. interventricular septum.
What is the function of anterior interventricular branch of left coronary artery?
What is the left anterior descending artery (AIV)?
Kim Bengochea, Regis University, Denver 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.
Where does the anterior interventricular artery end?
The artery ends approximately halfway along the inferior surface by anastomosing with the inferior interventricular branch (a.k.a posterior interventricular/posterior descending branch) of the right coronary artery. Within the anterior interventricular sulcus, the AIV is accompanied on the left side by the anterior interventricular vein.
What are the anterior and inferior interventricular septal branches?
Interventricular septal branches, which are divided into anterior and inferior. 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.
What does the anterior interventricular sulcus supply?
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. 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.
