Key result
Percutaneous coronary intervention and optimal medical therapy are evolving as viable alternatives to traditional coronary artery bypass graft surgery for left main coronary artery disease.
Why the study?
Advances in percutaneous coronary intervention and optimal medical therapy have challenged traditional coronary artery bypass graft surgery for left main coronary artery disease, particularly for narrowings between 40% and 69%.
This review summarizes the evolving management strategies for left main coronary artery disease, highlighting the roles of CABG, PCI, and medical therapy.
Remarkable advances in the management of coronary artery disease have enhanced our approach to left main coronary artery (LMCA) disease. The traditional role of coronary artery bypass graft surgery has been challenged by the less invasive percutaneous coronary interventional approach. Additionally, major strides in optimal medical therapy now provide a rich menu of treatment choices in selected circumstances. Although a LMCA stenosis >70% is an acceptable threshold for revascularization, those patients with a LMCA narrowing between 40 and 69% present a more complex scenario. This review examines the relative merits of the different treatment options, addresses key diagnostic and therapeutic unknowns, and identifies future work likely to advance progress.
