Interventions

QFRother

Patients suspected with CAD undergoing diagnostic coronary angiography with an indication for to perform invasive FFR were included. QFR was analyzed in an independent core laboratory (Uijeongbu Eulji Medical Center) using the software package QAngio XA 3D 2.1 (Medis Medical Imaging Systems, Leiden, the Netherlands).
