AIMS: The provisional strategy (PS) is an accepted modality of treatment in coronary bifurcation interventions, though, after main vessel (MV) stenting, the assessment of the side branch (SB) becomes more difficult. In bifurcation interventions, the major advantage of fractional flow reserve (FFR) is the avoidance of the need for SB intervention. However, SB access with a pressure wire after MV stenting may be difficult, sometimes impossible. The objective of this paper was to evaluate the feasibility and safety of physiologic assessment of SB lesions using FFR with the jailed pressure wire (JPW) in patients undergoing the PS. Although the JPW technique is theoretically possible in the PS, there is no information available on the use of this technique.

METHODS AND RESULTS: We retrospectively evaluated 11 patients who were treated with the JPW technique at a single centre. Procedures were successfully accomplished in all cases without complications, such as damage of the pressure sensor, failure to measure FFR value, removing the polymer coating, and entrapment or fracture of the JPW.

CONCLUSIONS: In conclusion, our limited experience suggests that the JPW technique in the PS may be a safe and technically feasible approach. This technical report details the JPW technique in patients undergoing the PS.
