Revascularization of unprotected left main coronary artery disease with percutaneous coronary intervention: the role of drug-eluting stents.
The percutaneous revascularization of left main coronary artery stenosis has until recently been reserved for patients at prohibitive surgical risk or for selected emergent cases. This adopted practice of coronary artery bypass grafting, as the standard of care for left main coronary artery stenosis, has largely occurred secondary to disappointing results with bare metal stents implanted in the left main coronary artery. However, in the current era of drug-eluting stents (DES) which significantly reduce restenosis compared to bare metal stents, there has been a renewed interest in examining the role of percutaneous coronary intervention as a means of revascularization of left main disease. This article discusses recent and ongoing studies investigating the role of percutaneous intervention of left main disease, with an emphasis on the use of DES for this purpose.
