Over the last months, 2 major trials and several meta-analyses have been published on the treatment of stable, unprotected left main coronary artery stenosis. Currently, North American and European guidelines for the treatment of left main stenosis indicate a class I recommendation for the performance of coronary artery bypass grafting (CABG). They also indicate a class IIa to III (North American) or a class I to III (European) recommendation for percutaneous coronary intervention (PCI), depending on the complexity of the coronary anatomy as determined by the Synergy Between PCI With Taxus and Cardiac Surgery (SYNTAX) score.1
