The ACIST RXi® Rapid Exchange System offers the ACIST diastolic pressure ratio (dpr) as a non-hyperemic solution for physiological assessment of coronary disease. This approach has the potential to decrease patient discomfort, lower costs, and reduce procedure time. Utilizing the Navvus®II Rapid Exchange FFR MicroCatheter, the ACIST RXi® System serves as an alternative to conventional pressure wires. It allows physicians to employ their preferred 0.014″ guidewire for dependable assessment of coronary physiology. Read on for an examination of the ACIST FFR Study.


Purpose: The data collected during the ACIST-FFR clinical study was retrospectively assessed by an independent, physiologic core laboratory to support ACIST’s dPR algorithm on the ACIST RXi System
