What is left main equivalent disease?

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 significant left main coronary artery?

Significant left main coronary artery disease is defined as a greater than 50% angiographic narrowing of the vessel. In general, there are three options for the treatment of LMCA disease which include optimal medical therapy, percutaneous revascularization, or surgical revascularization, either off-pump or on-pump.

Can you Stent left main coronary artery?

Left main coronary artery stenting is typically suitable for patients who are at high risk for surgical complications or have comorbidities.

What is the Widowmaker?

A widowmaker is an informal term for a heart attack that involves 100 percent blockage in the left anterior descending (LAD) artery, says Stanley Chetcuti, M.D., an interventional cardiologist at the University of Michigan Frankel Cardiovascular Center.

Which is better PCI or CABG?

From both short and long-term studies, it emerges that in patients with multivessel disease, coronary artery bypass grafting (CABG) is associated with better survival, lower rates of major cardiovascular events (specifically myocardial infarction or stroke) and repeat revascularization as compared with percutaneous …

What is significant left main equivalent disease (LMCA)?

Most trials of treatment and treatment guidelines define significant LMCA stenosis as a greater than 50% diameter stenosis, and left main equivalent disease is as severe (greater than or equal to 70%) diameter stenosis of the proximal left anterior descending and proximal left circumflex as judged by contrast angiography.

What is left main equivalent stenosis?

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).

Does the syntax score predict outcome in left main disease?

In left main disease, major adverse coronary and cerebral events (MACCE) was noninferior in the low and intermediate group but lower for surgery in the high-risk group. The SYNTAX score alone only modestly predicts long-term outcome.

What is the prevalence of left main artery disease?

Left main disease occurs with other coronary artery disease in 80% of patients. Stenosis occurs in the distal left main artery in two thirds of cases and proximally in the other third. Bifurcation stenoses were more likely to be more severe than other types of left main lesions.
