What percentage of blockage should be procedurally treated in the left main coronary artery?
Current clinical practice guidelines from both the American College of Cardiology/American Heart Association and the European Society of Cardiology recommend revascularization for all patients with ≥50% stenosis of the left main coronary artery (LM), regardless of symptomatic status or associated ischemic burden.
Can you live with 100 blocked LAD artery?
A widow maker is when you get a big blockage at the beginning of the left main artery or the left anterior descending artery (LAD). They’re a major pipeline for blood. If blood gets 100% blocked at that critical location, it may be fatal without emergency care.
Can you stent a 100% blocked artery?
“Patients typically develop symptoms when an artery becomes narrowed by a blockage of 70 percent or more,” says Menees. “Most times, these can be treated relatively easily with stents. However, with a CTO, the artery is 100 percent blocked and so placing a stent can be quite challenging.”
