What is cross border data transfer?

I agree on cross-border transfer of personal information.

I would like to receive marketing related electronic communications about Philips products, services, events and promotions that may be relevant to me based on my user preferences and behaviour.

Intravascular ultrasound (IVUS) is a catheter-based imaging technology that allows physicians to visualize blood vessels from the inside out. Cross-sectional images help assess presence and extent of disease, plaque geometry and morphology, guide wire position during lesion crossing, and stent position post-treatment. IVUS helps to decide, guide, and confirm the right interventional treatment for each patient.

How IVUS works

A transducer emits high-frequency sound waves that echo off vessel walls and are sent back to the system in varying intensities depending on the tissue. System electronics process the signal to display the cross-sectional image.

Precision-guided therapy system

The IVUS system offers an intuitive interface for optimal ease of use and provides your choice of IVUS and physiology on an integrated platform.

IVUS catheters

Philips Image Guided Therapy (IGT) Devices provides a full line of IVUS catheters to help guide your treatment approach for both coronary^† and peripheral^†† applications. Eagle Eye Platinum, with fast, plug-and-play simplicity, is the #1 choice of physicians for IVUS.¹

Key clinical scenarios

Bioresorbable scaffolds

IVUS may be used to optimize implantation by allowing you to observe:

Precise vessel size
Lesion length
Presence and extent of calcium
Stent expansion and apposition
Edge complications

Because of the thickness and material of the struts, it is common for the struts to present on ultrasound as a double line representing the leading and trailing edges of the strut.

Left main

IVUS may help to determine:

Lesion significance
Vessel sizing
Optimal stent deployment

Repeat patients

For repeat patients, IVUS may help determine:

Extent and mechanism of restenosis for optimal treatment strategy and for the decrease of risk of geographic miss
Location and amount of thrombus

Bifurcation lesions

IVUS may help to determine:

Plaque distribution
Whether two stents are needed
Lesion length
Landing zones
Whether post-dilation is needed (especially at the proximal stent)

Ambiguous angiogram

IVUS may help to determine pathology at the ambiguous site to optimize your treatment strategy and device utilization.

Ostial disease

For ostial disease, IVUS may help to determine location of true ostium to decrease risk of geographic miss or stent struts in the ostium.

Diffuse/long lesions

IVUS may help to determine:

Vessel size and length of disease
Positive remodeling
Plaque burden
Stenosis

IVUS benefits

PCI strategy changed 74% of the time.²

The ADAPT-DES study reported that IVUS guidance was associated with a change in PCI strategy 74% of the time.² Most often, the impact was a larger size of stent or balloon followed by post-dilation. Furthermore, the study reported that larger stent areas resulted in cases where both pre- and post-PCI IVUS were performed compared to when only post-PCI IVUS was performed.

34% reduction in MACE

The ADAPT-DES study reported that IVUS Guidance was associated with a 34% reduction in major adverse cardiac events (MACE) at 2 years (4.9% vs 7.4%, p < 0.001).³

Meta-analysis – largest study of IVUS guidance data

A large body of evidence from randomized trials, observational studies, and meta-analyses reports that IVUS guidance is associated with reduced MACE.^4,5,6,7,8

The Society for Cardiac Angiography and Interventions’ (SCAI) Expert consensus statement: “Definitely beneficial”⁸

IVUS is an accurate method for helping to determine:

Optimal stent deployment

- Complete stent expansion

- Apposition

- Lack of edge dissection or other complications after implantation

Size of the vessel undergoing stent implantation¹⁰

Quality metrics

In-hospital mortality is an important metric of the Medicare value-based purchasing program along with 30-day readmissions that influences hospital quality scores and Medicare’s withholding of payments.^11,12 IVUS guidance was associated with 0.4% in-hospital mortality while guidance by angiography alone was associated with 0.8% in-hospital mortality (p < 0.001), a 50% reduction.⁵ IVUS-guided DES placement has been shown to reduce 30-day event rates.^13,14
