Safety of Revascularization Deferral of Left Main Stenosis Based on Instantaneous Wave-Free Ratio Evaluation

The aim of this study was to assess the long-term clinical outcomes of patients with left main coronary artery (LM) stenosis in whom treatment strategy was based on the instantaneous wave-free ratio (iFR).The overall safety of iFR to guide revascularization decision making in patients with stable coronary artery disease has been established. However, no study has examined the safety of deferral of revascularization of LM disease on the basis of...
