What is the left main coronary artery?
What is the left main coronary artery?
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.
What is distal LM disease?
Background: Distal left main (LM) coronary artery bifurcation disease increases percutaneous coronary intervention (PCI) procedural complexity and is associated with worse outcomes than isolated ostial/shaft disease. The optimal treatment strategy for distal LM disease is undetermined.
Where is the left main artery located?
Location: The left coronary artery (left main coronary artery) emerges from the aorta through the ostia of the left aortic cusp, within the sinus of Valsalva. The plane of the semilunar valve is tilted so that the ostium of the left coronary artery is superior and posterior to the right coronary ostium.
What is left main disease?
Left main coronary artery (LMCA) disease is the highest-risk lesion subset of ischemic heart disease, and has traditionally been an indication for coronary artery bypass grafting (CABG).
Can the left main artery be stented?
Left main coronary artery stenting is typically suitable for patients who are at high risk for surgical complications or have comorbidities.
Can you stent the left main artery?
What is left main equivalent disease?
Left main disease Left main equivalent refers to one stenosis that serves a territory equal to a left main lesion (usually proximal LAD or circumflex, with an occlusion of the other major left coronary artery that is filled by collaterals from the patent LAD or circumflex coronary vessel).
What is protected left main disease?
protected left main disease refers to patients with patent bypass graft to one of 2 major left circulation branches (left anterior descending or left circumflex coronary artery) 2. unprotected left main disease (also called ULMD) refers to patients without bypass to the left coronary circulation 2.
