Diagnostic Accuracy of Angiography-Based Quantitative Flow Ratio Measurements for Online Assessment of Coronary Artery Stenosis
Conclusions
The FAVOR II China study met its prespecified primary performance goal for the level of diagnostic accuracy of QFR in identifying hemodynamically significant coronary stenosis. It demonstrated the clinical utility of QFR for use in diagnostic catheterization laboratories, and QFR bears the potential of improving angiography-based identification of functionally significant stenosis during coronary angiography.
