LAD Coronary Artery |
The
aortic valve has three leaflets, each having a cusp or cup-like configuration.
These are known as the left coronary (LC), right coronary (RC) and the
posterior non-coronary (NC) cusps. The latter is called a non-coronary
cusp because a coronary artery artery does not commonly originate from
this cusp. The left coronary artery arises from the left coronary cusp
and the the right coronary artery arises from the right coronary cusp. The
septal perforators are the other branches of the LAD and supplies
blood to the septum of the left ventricle. |

The aortic valve has three leaflets, each having a cusp
or cup-like configuration. These are known as the left coronary (LC),
right coronary (RC) and the posterior non-coronary (NC) cusps. The latter
is called a non-coronary cusp because a coronary artery artery does
not commonly originate from this cusp. The left coronary artery arises
from the left coronary cusp and the the right coronary artery arises
from the right coronary cusp. The LAD travels in the anterior inter-ventricular groove that
separates the right and the left ventricle, in the front of the heart.
The figure on the top left demonstrates what the coronary arteries look
like in the antero-posterior or AP view. The distal segment of the LAD is the terminal third of the artery. The septal perforators are the other branches of the LAD and supplies blood to the septum of the left ventricle. Thus, the LAD travels in the anterior inter ventricular (AIV) groove which runs in front of the heart, between the right and left ventricles.The Dx or diagonal is a branch of the LAD that runs diagonally away from the AIV groove and towards the antero-lateral portion of the heart. The septal perforators (SP) runs into the septum and provides its blood supply. |
