Intravascular Ultrasound Guidance for Complex High-risk Indicated Procedures
Belgium, France, Germany2,020 participantsStarted 2021-11-02
Plain-language summary
The IVUS CHIP trial is a post-marketing strategy study in which patients with complex coronary lesions, undergoing percutaneous coronary intervention (PCI), are treated either with intravascular ultrasound (IVUS) guided PCI or angiographic guided PCI .
The IVUS-guided PCI approach is indicated to reduce the frequency of target-lesion failure (cardiac death, target-vessel myocardial infarction, and clinically indicated target-lesion revascularization) in patients with complex coronary lesions undergoing PCI.
The objective of this study is to assess the superiority of an IVUS-guided approach versus an angio-guided approach in patients with complex coronary lesions undergoing PCI.

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Target-vessel failure comparison of IVUS-guided PCI to angio-guided PCI in patients with complex coronary lesions
Timeframe: From date of randomization until the analysis cut-off date at approximately 15-18 months of median follow-up
. IVUS is strictly required for pre-PCI lesion severity assessment
. Requiring PCI in a diseased aorto-coronary bypass
. Known contraindication or hypersensitivity to everolimus, platinum-chromium, or to anticoagulants
. Absolute contraindications or allergy that cannot be pre-medicated, to iodinated contrast or to antiplatelet drugs, including both aspirin and P2Y12 inhibitors
. Non-cardiac co-morbidities with a life expectancy less than 1 year
. Currently participating in another trial that is not yet at its primary endpoint. The patient is not allowed to participate in another investigational device or drug study until the trial primary endpoint time point is achieved and may only be enrolled once in the study
