Plain-language summary

The objective of this clinical trial is to understand the effectiveness and safety of the OmniHeart 4.0 percutaneous ventricular assist device produced by ShanghaiDynaheart Medical Technology Co., Ltd. in providing hemodynamic support for high-risk PCI patients. The main questions it aims to answer are: During the treatment of high-risk PCI, will the application of the OmniHeart 4.0 percutaneous ventricular assist device achieve hemodynamic support that is not inferior to that of ECMO? What medical problems will occur during or after the treatment for participants who receive the OmniHeart 4.0 percutaneous ventricular assist device during high-risk PCI treatment? The researchers will compare the OmniHeart 4.0 percutaneous ventricular assist device with ECMO (a mechanical circulatory support device) using ECMO as the control group to compare the efficacy differences between the two and thereby evaluate the effectiveness and safety of the OmniHeart 4.0 percutaneous ventricular assist device in high-risk PCI treatment. Participants will: Be randomly assigned in a 1:1 ratio according to need during high-risk PCI treatment to either the experimental group or the control group. The experimental group will receive the OmniHeart 4.0 percutaneous ventricular assist device for assistance, while the control group will receive the veno-arterial extracorporeal membrane oxygenation (VA-ECMO) device for assistance. Check-ups and follow-ups will be conducted during the device usage period, at the time of weaning from the device, before discharge, 30 days after surgery, and 90 days after surgery. The effectiveness endpoint will be evaluated by recording indicators such as the incidence of major adverse cardiovascular and cerebrovascular events (MACCE) free of death within 30 days after surgery.

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.
