Abstract
The technical and device refinements in percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) has achieved the improvement of outcome in patients with coronary artery disease (CAD). Optimal revascularization methods (PCI or CABG) for severe CAD such as multivessel and / or left main CAD is still in debate in the current clinical practice. In this review, therefore, we discuss the current status of coronary revascularization and outcome in patients with severe CAD on the basis of the evidence of clinical trials in DES era.
