Enrolment begins in the ACIST-FFR multi-centre study


The first patient in the ACIST-sponsored FFR study—Assessment of Catheter-based Interrogation and Standard Techniques for Fractional Flow Reserve (FFR) measurement—was enrolled by William Fearon, professor of cardiovascular medicine at Stanford University, Palo Alto, USA on the 14th November.

Led by co-principal investigators, Matthew Price Scripps Clinic, La Jolla, USA and William Fearon, Stanford Hospital, Palo Alto, USA, the purpose of the ACIST-FFR Study is to advance clinical understandings of FFR technologies. The researchers will investigate measurement accuracy, incidence of drift and device success in 240 patients at 12 US sites. The results of the study are predicted by ACIST medical systems to demonstrate the FFR clinical utility of their Navvus rapid exchange FFR microcatheter.

In 2014, ACIST Medical Systems, Eden Prairie, USA launched the ACIST RXi Rapid Exchange FFR System and Navvus Rapid Exchange FFR Microcatheter. This rapid exchange FFR technology is designed to allow physicians to use their preferred 0.014″ guide wire throughout the procedure, and so address the challenges of pressure wires, including accessibility in challenging anatomies, maintaining wire position, pressure-measurement drift and ease of obtaining post-intervention FFR.
