Treatment of unprotected left main disease with drug-eluting stents in patients at high risk for coronary artery bypass grafting.

Abstract

BACKGROUND: Percutaneous coronary intervention (PCI) for high-grade stenosis of the left main coronary artery with bare-metal stents has been limited by restenosis, and most patients are managed with coronary artery bypass grafting (CABG). Recently, drug-eluting stents (DES) have reduced instent restenosis after PCI, but their role in the treatment of left main disease remains unclear. AIMS: The aim of this study was to determine the outcomes after utilizing DES to treat left main disease. METHODS: Twenty consecutive symptomatic patients with >50% angiographic stenosis of the left main coronary artery with no prior history of CABG ["unprotected left main" (ULM)] underwent PCI with DES.
