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

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...
