title: Stenting of unprotected left main coronary artery stenosis.
abstract: Unprotected left main stenosis greater than 50% has traditionally been managed with coronary artery bypass surgery. There is now emerging evidence to support a percutaneous strategy adopting drug-eluting stents, especially in patients at high risk for surgery. This paper will review recent outcomes of both bare-metal and drug-eluting stent use for unprotected left main stenosis and summarise results of an Australian registry. Results of studies comparing the percutaneous approach to surgery will also be reviewed together with ESC and AHA/ACC current guidelines. Although percutaneous intervention of unprotected left main has been shown to be a safe and feasible procedure, unanswered questions remain. Large multi-centre randomised trials underway comparing percutaneous to surgical intervention will help clarify these ongoing issues.
