Little is known about post–intervention fractional flow reserve (FFR) in Endovascular Therapy. The purpose of this study was to assess utility of FFR (based on systolic pressure) in the endpoint determination after iliofemoral intervention.
62 iliofemoral disease patients were measured post–intervention peripheral FFR (pFFR) using by 300cm pressure wire. In addition, post–intervention systolic pressure gradient ratio of lesion distal to proximal (named pFFR–systolic). We compared them with post–procedural Peak Systolic Velocity (PSV) demonstrated by duplex ultrasound retrospectively.
Post–procedural ABI significantly higher than baseline (0.91±0.15 vs 0.67±0.24, P < 0.0001). Post–intervention pFFR was not significantly correlated with post–procedural PSV (R=–0.35, P=0.038). However, Post–intervention pFFR–systolic was significantly negative correlated with post–procedural PSV (R=–0.60, P<0.001).
Post–intervention pFFR–systolic could be useful in the endpoint determination after iliofemoral intervention.
