Background

Fractional flow reserve derived from coronary computed tomography angiography (FFRCT), Quantitative flow ratio (QFR), and Murray law-based quantitative flow ratio (¥ìQFR) are non-invasive tools for diagnosing obstructive CAD. 

Methods

This study compares FFR at sequential side branches in patients with complex CAD using three different software tools. It is a post-hoc analysis of the FASTTRACK CABG study. All patients in this study underwent CCTA and angiography before CABG. FFRCT was calculated using the HeartFlow software,  QFR using  Medis QAngio XA 3D 2.1 software,  and µFR  using Pulse  AngioPlus (Version 3.0) software. FFR values were calculated at sequential side branch points (SB) with all 3 softwares by 3 independent analysts. All SBs were marked by a blinded matcher after co-registration of CCT angiography with the fluoroscopic angiography view. 

Results
