TCT-255 Impact of right atrial pressure on fractional flow reserve calculation in the presence of a chronic total occlusion

Background Fractional flow reserve (FFR) is calculated as the ratio of mean distal coronary pressure (Pd) to mean aortic pressure (Pa) during maximal hyperemia. The aim of this study was to assess the impact of mean right atrial pressure (Pra) on collateral donor vessels FFR measurements in the pres...
