Brief 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.

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • \- 1. The patient's age is between 18 and 90 years old (inclusive). 2. There is at least one lesion (including primary lesions and restenosis lesions) in the native coronary artery or grafted bypass vessel, and percutaneous coronary intervention (PCI) needs to be performed under hemodynamic support.
  • \. The patient meets one of the following conditions:
  • The left ventricular ejection fraction (LVEF) is \<=35%, and the vessel to be treated with interventional therapy is an unprotected left main coronary artery lesion or a lesion with only a single remaining open vessel.
  • The left ventricular ejection fraction (LVEF) is \<=30%, and the vessel to be treated with interventional therapy is a three-vessel coronary artery lesion.
  • Among them, a three-vessel coronary artery lesion is defined as follows: there is at least one significant stenosis in each of the three main epicardial coronary arteries (the left anterior descending branch and/or its branches, the left circumflex branch and/or its branches, the right coronary artery and/or its branches). A significant stenosis is defined as a luminal stenosis \>= 50% (by visual inspection) or complete occlusion, and at least two vessels have a luminal stenosis \>= 70%. For left-dominant coronary arteries, the presence of \>= 50% stenosis in both the left anterior descending branch and the proximal left circumflex branch is also regarded as a three-vessel coronary artery lesion.
  • \. The subject or his/her legal guardian is able to understand the purpose of the trial, voluntarily participates in the trial and signs the informed consent form, and is willing to complete the follow-up as required by the trial.

  • \. A history of stroke or transient ischemic attack (TIA) within 1 month before enrollment.
  • \. Allergic or intolerant to iodine contrast agents, heparin, aspirin, ADP receptor inhibitors, and with a history of heparin-induced thrombocytopenia (HIT) in the past.
