Summary
Murray-law based single-view quantitative flow ratio (µQFR) has been recommended for guiding percutaneous coronary intervention (PCI) in selective patients. However, it's reliability has not been validated in bifurcation lesions which present complex anatomy and flluid conditions before and after PCI. The goal of this study is to investigate the diagnostic performance of µQFR in side branch after single-stent treatment for bifurcation lesions in patient with obstructive coronary artery diseases.
