In a coronary CT scan, what exactly does the LAD score and …
2014年3月10日 · Calcium in the coronary circulation roughly tracks the amount of plaque – the higher the score, the more plaque. Obviously, a score of “zero” is optimal, and a score of >300 (or >400, depending upon who you listen to) warrants further work-up, like a …

2008年10月14日 · The LCA divides almost immediately into the circumflex artery (Cx) and left anterior descending artery (LAD). On the left an axial CT-image. The LCA travels between the right ventricle outflow tract anteriorly and the left atrium posteriorly and divides into LAD and Cx.
The Coronary Arteries – The Cardiovascular - ECG & ECHO
Arteries to the posterior wall (these arteries branch of after the right marginal artery) may be given off by the RCA (and otherwise the LCx). The LAD supplies the anterior two-thirds of the interventricular septum (this area is referred to as anteroseptal area).

2024年6月28日 · The left coronary artery has a short common stem (and is hence often referred to as the left main coronary artery), that bifurcates into the left circumflex artery (LCx), which courses over the left atrioventricular groove, and the left anterior descending artery (LAD), which passes towards the apex in the anterior interventricular groove.
Coronary artery anomalies overview: The normal and the abnormal
Normally, there are three main coronary arteries, the right coronary artery (RCA), left circumflex artery (LCX) and left anterior descending (LAD), with the LCX and LAD arteries arising from a common stem, the left main coronary artery (LMCA).

2023年7月24日 · The RCA and LMCA extend from the aortic root to supply different regions of the heart. The RCA gives rise to the sinoatrial nodal branch of the right coronary artery, posterior descending artery branch of the RCA, and the marginal branch. The LMCA branches into the circumflex and LAD.
Anatomy and Terminology for the Interpretation and Reporting of …
Image in 58-year-old man with multiple cardiac ischemic risk factors who presented with chest pain shows left main artery (curved arrow), left anterior descending (LAD) artery (arrowhead), and left circumflex artery (straight arrow). LAD also gives rise to diagonal branches.
Anatomy, Thorax, Heart Anomalous Left Anterior Descending (LAD) Artery
This article will describe in detail the normal structure and function of the LAD, embryologic anomalies of the LAD, surgical considerations, and clinical significance of anomalous LAD. Coronary anomalies of the left anterior descending artery (LAD) are very rare, with a frequency of less than 1% in the general population.[1]
Coronary… | The American Association for Thoracic Surgery - AATS
The left main coronary artery originates from the left coronary sinus of the aorta and courses between the pulmonary trunk and the left atrial appendage. The left coronary artery then divides into the LAD artery and the circumflex artery, with an occasional ramus intermedius artery in the middle of these two branches.

2023年1月27日 · The left anterior descending artery (LAD) is the largest coronary artery that runs anterior to the interventricular septum in the anterior interventricular groove, extending from the base of the heart to the apex. The LAD gives 2 sets of branches.
