No results posted yet for this study

Summary

Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. Virtual stent implantation technique combined with QFR was recently developed to predict the functional significance of coronary stenosis as if the stenosis was revascularized.

The purpose of this study is to evaluate the diagnostic accuracy of QFR in in tandem lesions with fractional flow reserve (FFR) as the reference standard. The secondary purpose is to evaluate the diagnostic accuracy of QFR-based virtual stent technique in predicting the FFR values after revascularizing the culprit lesion.
