Abstract
PURPOSE OF REVIEW: This review attempts to specifically assess impact of disease location in left main artery on mortality and cardiovascular outcomes in patients treated with percutaneous coronary intervention versus coronary artery bypass surgery. RECENT FINDINGS: The management of left main disease, once thought to be the sole province of cardiothoracic surgeon, has recently undergone a reappraisal by the cardiovascular medicine community. For many years, societal guideline recommendations advised bypass surgery as the "de rigeur" method of revascularization for unprotected left main disease. However, recent studies suggest that coronary intervention, especially with advances in drug-eluting stent technology, has mounted a serious challenge to surgical bypass in treatment of this disease. Although overall mortality rates are comparable for percutaneous coronary intervention and bypass surgery, left main disease location does influence long-term outcomes for percutaneous coronary intervention more than bypass surgery. A patient- and lesion-centered approach to treatment of this disease may provide optimal outcomes.
