Is it time for elective left main percutaneous coronary intervention to become ‘main stream‘?

Left main (LM) stenting is considered by many to be one of the last frontiers of interventional cardiology. Begin-ning with the VA cooperative study published in 1976 demon-strating a mortality benefit for patients undergoing coronary artery bypass grafting (CABG), ' the standard of care for treat-ment of left main coronary artery disease has been surgical. The most recent 2005 update of the ACC/AHA/SCAI Practice Guidelines on PCI2 again notes that "CABG using IMA graft-ing is the 'gold standard' for treatment of unprotected left main disease and has proven benefit on long-term outcomes."
