Plain-language summary
Coronary calcified lesions will have an increasing impact in the daily practice of coronary angioplasty, considering the epidemiological explosion of factors favoring coronary calcifications, first of all diabetes. Moreover, calcified lesions are underestimated in angiography and associated with an increase in angiographic complications, as well as with a worse clinical prognosis. The usual techniques for the preparation of calcified plaque, in particular rotary atherectomy, have a low penetration rate in France (3% of procedures) and are associated with an increase in per-procedural complications without clinical evidence of effectiveness4. A new device has been developed by Schockwave Medical Inc. for the treatment of calcified lesions to facilitate stent delivery: the C2 Shockwave Medical® Coronary Lithotripsy System (IVL), Inc. This system uses the principle of lithotripsy to induce microfractures in the calcified plaque prior to low-pressure balloon dilatation. The objective of the study is to evaluate the safety and performance of the C2 Shockwave Medical® (IVL), Inc. coronary lithotripsy system in coronary angioplasty in the general population in France.

Questions worth asking your doctor
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?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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.
