Coronary artery bypass surgery or drug eluting stent for unprotected left main coronary artery disease.

ABSTRACT

Coronary artery bypass surgery (CABG) is the treatment of choice in unprotected left main coronary artery disease (ULMCA). However drug eluting stent (DES) implantations in ULMCA have ushered a revolution in the field of percutaneous coronary interventions (PCI) for left main coronary artery (LMCA) by reducing peri-procedural mortality and incidence of major adverse cardiac events (MACE). More randomized trials and follow-up studies are required before PCI with DES can be chosen as alternative to CABG.
