Operator Experience and Outcomes After Left Main Percutaneous Coronary Intervention
- 75 Downloads
Purpose of Review
This review was performed with the goal of summarizing the role of operator experience in the treatment of severe left main stenosis by percutaneous intervention techniques.
The Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization (EXCEL) trial demonstrated that percutaneous coronary intervention and coronary artery bypass grafting had similar clinical outcomes for severe left main disease. However, PCI of the left main coronary stenosis is considered to be a high-risk intervention because of the large area of myocardium at jeopardy that can quickly cause hemodynamic compromise. Operator experience and familiarity with the use of hemodynamic support devices, plaque modification techniques, and intravascular imaging tools is associated with better clinical outcomes.
In patients with severe left main stenosis undergoing percutaneous coronary intervention by high-volume operators, the clinical outcomes are superior.
