DEFINE PCI study finds treatable cause for significant rates of residual ischemia in coronary stent patients


(MENAFN- EIN) / EIN News / -- March 17, 2019









  • Nearly one in four patients in the study treated with standard of care percutaneous coronary intervention (PCI) had residual ischemia after coronary stent implantation intended to relieve severe blockages and improve blood flow
  • Physiologic guidance tools such as iFR pullback measurements combined with Philips’ SyncVision iFR Co-registration enable physicians to precisely identify, locate and treat the ischemia, offering promise to further improve PCI outcomes
  • Amsterdam, the Netherlands and New Orleans, U.S. – At the American College of Cardiology’s (ACC) annual meeting in New Orleans, U.S., Royal Philips (NYSE: PHG, AEX: PHIA), a global leader in health technology, today announced the results of the DEFINE PCI [1] study, which assessed the level of residual ischemia found in patients after percutaneous coronary interventions (PCI). This study found that 1 in 4 patients [1] treated with standard of care PCI left the cath lab with residual ischemia (iFR Tailored for advanced physiologic guidance
    iFR is well established for determining whether a vessel is indicated for treatment through the landmark DEFINE FLAIR and iFR Swedeheart outcome studies, both published in the New England Journal of Medicine [4, 5]. The one-year patient outcomes were consistent with fractional flow reserve (FFR), while iFR involved less procedural time, reduced patient discomfort, and reduced cost [6]. Philips SyncVision iFR Co-registration further advances physiology by mapping the pressure profile of the whole vessel onto the angiogram, providing physiologic guidance for where to treat within the vessel. With iFR Co-registration, physicians can identify the precise locations causing ischemia, plan stent length and placement with a virtual stent, and predict physiologic improvement. Philips SyncVision with iFR Co-registration provides physicians with a full physiologic image allowing them to see clearly and treat optimally. 

    “As iFR continues to be adopted into clinical practice, the DEFINE PCI study is the latest addition to mounting evidence that this innovative technology contributes to reducing costs, improving outcomes [4, 5, 7] and enhancing the patient experience,” said Christopher Barys, Business Leader Image Guided Therapy Devices, Philips. “With SyncVision with iFR Co-registration, we are providing physicians with the complete picture, allowing for more optimal treatment of their patients.”

    Philips SyncVision with iFR Co-registration is part of Philips’ unique portfolio of systems, smart devices, software and services in image-guided therapy, which combine to provide healthcare providers with sophisticated, procedure-oriented solutions. It is currently being showcased at ACC in booth #1901. Follow the #ACC19 conversation on @PhilipsLiveFrom throughout the event. More information about iFR Co-registration is available  here . DEFINE PCI is the latest in a series of research on iFR techniques, building from the DEFINE FLAIR study in 2017, with economic results in 2018.
