SR Print(0) ID 1160206810 T1 Left Main Coronary Artery Disease: Approach to Percutaneous Intervention T2 Color Atlas and Synopsis of Interventional Cardiology YR 2018 FD 2018 PB McGraw-Hill Education PP New York, NY SN 9780071749350 LK accesscardiology.mhmedical.com/content.aspx?aid=1160206810 RD 2024/10/05 AB In 1912, James Herrick reported the first description of left main coronary artery (LMCA) occlusion when he described the case of a 55-year-old man who died of cardiogenic shock and was subsequently found on autopsy to have extensive necrosis of the left ventricle associated with thrombotic occlusion of the LMCA superimposed on an area of atherosclerotic narrowing.1 It is now estimated that 4% to 6% of patients undergoing coronary angiography have significant LMCA disease defined as ≥50% stenosis, with more than two thirds noted to have concurrent multivessel disease.2,3 Insofar that interventional cardiologists are usually the first in diagnosing and often determining treatment strategies for LMCA stenoses, it is important to have a thorough understanding of the disease process in order to make informed decisions for this complex disease process.
