Elevate your physiologic decision-making with iFR Co-registration

Only Philips iFR Co-registration helps you decide where to treat by mapping the iFR pull back directly onto the angiogram for a new dimension in PCI guidance.  Confident assessment: 38% of stenoses severity classifications changed when using iFR Co-registration compared to using angiography alone [3,4]. Minimize unnecessary stent placement: iFR Co-registration helps identify lesions that will truly benefit from PCI. Tailored intervention: Obtain additional perspective on PCI planning by helping identify strategies for the most physiological gain.

Demonstrated results

    1 in 4

    patients with successful PCI left the cath lab with residual ischemia

    (defined as iFR <0.90 residual DS <50% in any treated lesion) [1].

  2. 81.6%

    of patients with ischemia, were caused by an inapparent focal stenosis

    81.6%

    of patients with ischemia, were caused by an inapparent focal stenosis

    with residual ischemia, were caused by an untreated angiographically inapparent physiologically focal stenosis (≤ 15 mm) [1].

  3. 79%

    reduction in residual ischemia

    79%

    reduction in residual ischemia

    if all focal lesions had been successfully treated (24% to 5%) [1].

  4. 68%

    relative relative reduction in clinical events

    68%

    relative relative reduction in clinical events

    in clinical events at 1 year follow-up among patients achieving post-PCI iFR ≥ 0.95 (p-value=0.04) [2].

Virtually plan your PCI and predict results
Angiography provides a visual picture, but often lacks the detail needed for optimal PCI planning. Only Philips provides advanced physiologic guidance to help you determine not just whether to treat, but also where to treat, ensuring precise, patient-focused care.
1. Identify the precise locations causing ischemia - each yellow dot signifies a 0.01 drop of iFR
2. Plan your treatment, before a stent is even placed, with a virtual stent
3. Determine lesion lengths without need for a pullback device
4. Predict physiologic gain with iFR Estimate to determine the best treatment strategies
