The Contemporary Management of Left Main Coronary Artery Disease.

The 'gold standard' in the management of left main coronary artery disease has historically been coronary artery bypass surgery. Recent innovations in drug-eluting stent technology coupled with the increasing utility of physiology and imaging guidance for procedures have led to an evolving role of percutaneous coronary intervention in left main disease of low and intermediate anatomical complexity. This revascularization modality carries the clear advantage of being less invasive and significantly reduced recovery times. This practice is currently supported by international guidelines, however, it remains a controversial topic in the field of interventional cardiology, and the long-term outcomes of a percutaneous strategy have been questioned. This review describes the current evidence base for the assessment and choice of intervention in left main coronary artery disease. The percutaneous revascularization techniques and use of imaging to optimize procedures and improve clinical outcomes have been discussed.
