left main coronary artery disease
Atherosclerotic narrowing of the left main coronary artery, considered high-risk due to large myocardial territory supplied.
Full Definition
Stenosis affecting the left main coronary artery, which supplies blood to the left anterior descending and left circumflex arteries. This condition is considered particularly high-risk because occlusion would compromise a large portion of the left ventricular myocardium. Treatment decisions typically involve choosing between percutaneous coronary intervention and coronary artery bypass grafting, with specific criteria based on anatomical complexity and patient factors.
Usage
Usage note: Distinguish between distal left main (involving bifurcation) and ostial/mid-shaft disease.
