Jun 21, 2012 · Distal LAD disease is presence of plaques in the vessel beyond two major branches. LAD stands for left anterior descending coronary artery.

Jun 8, 2014 · Heart blockage is a term commonly used by patients referring to coronary artery disease, a build-up of plaque causing narrowing of the arteries that supply the heart muscle with blood.

Septals originate from the LAD at 90 degrees to the surface of the heart, perforating and supplying the anterior 2/3 of the interventricular septum. Diagonals run along the surface of the heart and supply the lateral wall of the left ventricle and the anterolateral papillary muscle.

Feb 11, 2015 · LAD stands for left anterior descending artery. It is a coronary artery, which is the name given to arteries that supply the heart muscle with blood. The LAD is considered the most important of the three main coronary arteries and is almost always the largest.

The left coronary artery (LCA, also known as the left main coronary artery, or left main stem coronary artery) is a coronary artery that arises from the aorta above the left cusp of the aortic valve, and supplies blood to the left side of the heart muscle. [citation needed] .

Jan 27, 2023 · These are also numbered D1 and D2, onwards starting from proximal to distal. Around the apex, the LAD anastomoses with the terminal branches of the posterior descending artery, usually a branch of the right coronary artery.

Sep 1, 2009 · Coronary angiogram still shot showing distal left main coronary artery and tight left anterior descending coronary artery disease in a left anterior oblique caudal view.

Nov 7, 2016 · Stenosis of mid segment of left anterior descending (LAD) coronary artery seen on anteroposterior (AP) cranial view just after diagonal branch. Distal LAD is relatively narrow and there is mild ectasia just after the LAD stenosis. Proximal LAD also shows mild plaques.

The distal left anterior descending artery is referred to as L3. It extends from the origin of the third septal artery to the apex of the left ventricle. If there is no third septal branch, then the third segment begins halfway between S1 and the apex of the left ventricle.

Feb 22, 2025 · distal: distal to half the distance from the D1 origin to the apex. The LAD should arise from the left coronary cusp which lies between 3 and 6 o'clock on an axial view. The length of the LAD can be highly variable. On angiography, it may be reported as types I-III: type I: short vessel (can terminate before apex) type II: intermediate vessel
