November 3, 2017 — Acist Medical Systems Inc., a Bracco Group Company, announced the global launch of its Acist RXi Mini System, the next-generation system of its RXi Rapid Exchange FFR System. The RXi Mini System debuted at the 29th Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, Oct. 29-Nov. 2 in Denver.
The RXi Mini is designed to provide fractional flow reserve (FFR) measurements to complement angiography, provide qualitative assessment of lesion severity, and inform intervention strategy in both diagnosis and treatment of coronary and peripheral artery disease. The system is designed to seamlessly integrate with existing hemodynamic systems and FFR software. The RXi Mini offers flexible mounting configurations, a simple and intuitive user interface, and a small and unobtrusive system profile that adapts to users’ existing workflow and maximizes procedural efficiency.
The first case in the United States and the world was performed by Michael Lim, M.D., and director of cardiology at St. Louis University. During a complex case performed by Lim, the RXi Mini System was utilized to measure FFR multiple times during the procedure. Lim noted “Acist has raised the bar in making physiology accessible and easy to use in the cath lab setting.” The small RXi Mini system is about the size of a fist and connects into hospital hemodynamic systems where the measurements can be taken and recorded by lab staff, making the procedure go more smoothly and quickly. “FFR is the gold standard in diagnosing which lesions will most likely benefit from coronary interventions, including stent placement. The Acist Rapid FFR Mini RXi system makes it much simpler to perform FFR, whenever it is called for. With this advance, it continues to become easier to guide treatment decisions by invasive physiologic measurement – there really aren't that many excuses left for the interventionalist to skip this step.”
Unlike standard pressure wires, the Acist RXi Mini System and Navvus Rapid Exchange FFR MicroCatheter, allows physicians to use their 0.014-inch guide wire of choice throughout the procedure, addressing challenges of pressure wires, including accessibility in challenging anatomies, maintaining wire position, pressure‐measurement drift and ease of obtaining post‐intervention FFR.
