摘要
Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) disagrees on the hemodynamic significance of a coronary lesion in approximately 20% of cases. It is unknown if the physiological pattern of disease is an influencing factor for this discordance. This study assessed whether the
