TCT 2017: Next-generation FFR system launched

424

Acist has announced the global launch of its RXi Mini system—the next-generation system of its RXi Rapid Exchange fractional flow reserve (FFR) system. The system made its debut at the 2017 Transcatheter Cardiovascular Therapeutics (TCT) meeting last week.  

According to a press release, the RXi Mini is designed to provide FFR measurements to complement angiography—providing qualitative assessment of lesion severity and informing intervention strategy in both diagnosis and treatment of coronary artery disease and peripheral arterial disease. The system is designed to seamlessly integrate with existing haemodynamic systems and FFR software. The RXi Mini also offers flexible mounting configurations, a simple and intuitive user interface, and a small and unobtrusive system profile that adapts to operator’s existing workflow and maximizes procedural efficiency.

The first case in the USA and the world was performed by Michael Lim (St Louis University, St Louis, USA). During a complex case performed by Lim, the RXi Mini system was used to measure FFR multiple times during the procedure. He notes: “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 haemodynamic systems where the measurements can be taken and recorded by lab staff, helping the procedure to be performed more smoothly and quickly.

The press release reports that, unlike standard pressure wires, the ACIST RXi Mini system and Navvus rapid exchange FFR microcatheter allow physicians to use their 0.014” guidewire 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.

“Acist is excited about the additional value and flexibility that the RXi Mini will provide the cath lab. This next generation FFR solution reflects our continued organizational commitment to providing technologies that simplify procedures and help physicians improve patient care,” says Brad Fox (president and CEO, ACIST Medical Systems).
