What is interarterial?
: situated between the atria of the heart.
What is the course of left coronary artery?
The left coronary artery travels from the aorta, and passes between the pulmonary trunk and the left atrial appendage. Under the appendage, the artery divides (and is thus a very short vessel) into the anterior interventricular (left anterior descending artery) and the left circumflex artery.
What is anomalous left coronary artery?
Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a congenital (present at birth) heart defect in which the left coronary artery arises abnormally from the pulmonary artery. Normally, the left and right coronary arteries arise from the aorta and supply blood with oxygen to the heart.
What are the branches of left coronary artery?
The left coronary artery continues into the superior aspect of the anterior interventricular groove where it bifurcates into its two terminal branches; the left anterior descending artery (anterior interventricular artery) and the circumflex artery.
Why left coronary artery is important?
The left main coronary artery supplies blood to the left side of the heart muscle (the left ventricle and left atrium). The left main coronary divides into branches: The left anterior descending artery branches off the left coronary artery and supplies blood to the front of the left side of the heart.
Which artery is the most critical branch of the left coronary artery?
The LAD typically supplies 45–55% of the left ventricle (LV) and is therefore considered the most critical vessel in terms of myocardial blood supply.
How common is anomalous coronary artery?
An anomalous origin of one or more coronary arteries has been detected in approximately 0.27% to 1.66% of patients undergoing coronary angiography, with a rate of 0.6% detected in autopsy series (2–11).
Which is the artery of sudden death?
Of the left coronary artery arising from the right aortic sinus, especially the interarterial type, where the left coronary artery passes anteriorly between the aorta and the right ventricular outflow tract, is the type in which the patient is at risk of sudden death.
