European Bifurcation Club 2019, EBC 2019 - Barcelona, Spain NEWS 2 Feasibility and Efficacy of the Jailed Pressure Wire Technique for Coronary Bifurcation Lesions Author: Manuel Pan, MD, Reina Sofia Hospital, Spain BACKGROUND Evaluation of side branch result during PS: A current challenge When to dilate or stenting the side branch? When to do anything else? Until now, good result: TIMI III flow and no significant compromise of SB ostium FFR is a good method to evaluate SB compromise. OBJECTIVES Safety and feasibility of jailed pressure wire. Utility of physiological SB evaluation using iFR as a new index CONCLUSION The use of jailed pressure wire to monitor SB results for bifurcations treated by provisional stenting seems to be safe. The iFR index seems to provide new physiological information about the significance of the SB stenosis.
