Site vs. core laboratory variability in computed tomographic angiography-derived SYNTAX scores in the SYNTAX III trial

To investigate the variability between site and core laboratory (CL) calculation of the anatomical SYNTAX score (SS) based on coronary computed tomography angiography (CTA) alone and functional SS based on coronary CTA and fractional flow reserve derived from computed tomography (FFRCT) in the SYNTAX III trial.The SYNTAX III trial was a multicentre, international study that included 223 patients with three-vessel disease with or without left...
