The anterior interventricular sulcus is situated on the sternocostal surface of the heart, close to its left margin. The anterior interventricular branch of the left coronary artery runs in the sulcus along with the great cardiac vein.
What does anterior interventricular sulcus contain?
anatomy of heart
The other, the anterior interventricular sulcus, runs along the line between the right and left ventricles and contains a branch of the left coronary artery.
What is the function of the posterior interventricular sulcus?
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.
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.
Which vein drains most of the anterior ventricles?
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.
What is the function of the anterior interventricular branch of left coronary 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 supplies the interventricular septum?
The posterior interventricular artery, a branch of right coronary artery, supplies the posterior 1/3 of the interventricular septum. The remaining anterior 2/3 is supplied by the anterior interventricular artery which is a septal branch of the left anterior descending artery, which is a branch of left coronary artery.
What lies in the interventricular groove?
The interventricular groove runs anteriorly toward the apex and contains the great cardiac vein. Posteriorly, it continues along the inferior surface of the heart toward the right margin and contains the middle cardiac vein.
Which vessel travels in the right atrioventricular sulcus?
The right coronary artery can be found variably superficial or deep to the vein along its course in the atrioventricular groove. The anterior cardiac veins may also receive blood from the right marginal vein as it travels along the acute cardiac border.
What does the posterior interventricular a supply?
The posterior interventricular artery (in 90% of individuals), which supplies the posterior one-third of the interventricular septum, the inferior surface of the right ventricle and a portion of the inferior surface of the left ventricle.
What supplies blood to the myocardium?
The coronary arteries provide the main blood supply to the heart. The coronary arteries also supply the myocardium with oxygen to allow for the contraction of the heart and thus causing circulation of the blood throughout the body.
Where is anterior interventricular?
The anterior interventricular artery, often clinically termed the left anterior descending artery, is a branch of the left coronary artery. It originates at the left margin of the pulmonary trunk, anterior to the left atrial auricle.
What structure is embedded in the interventricular sulcus?
The interventricular sulcus contains the left anterior descending coronary artery and the left coronary vein embedded within adipose tissue.
Why is it called a Widowmaker?
A heart attack is particularly dangerous when it’s caused by blockage in the left anterior descending artery, which supplies blood to the larger, front part of the heart, earning it this scary-sounding nickname.
What is the anterior interventricular a called clinically?
The anterior interventricular artery, often clinically termed the left anterior descending artery, is a branch of the left coronary artery. It originates at the left margin of the pulmonary trunk, anterior to the left atrial auricle.
Which artery is called the Widowmaker?
A widowmaker is an informal term for a heart attack that involves 100 percent blockage in the left anterior descending (LAD) artery, says Stanley Chetcuti, M.D., an interventional cardiologist at the University of Michigan Frankel Cardiovascular Center.
