Secondary Endpoints:
30-day survival after transition to long-term therapy (VAD/transplant); 30-day cardiovascular mortality after device explantation; MACCE incidence; Mean support duration; Incidence of bleeding, thrombosis, hematologic events, acute renal/hepatic dysfunction, infection; Hemodynamic trends during support; Changes in SCr, BUN, ALT, TBIL at use, discharge and 30 days post-explantation vs baseline; Device satisfaction. Follow-up: Within 6 hours of initiation, during support, 24 hours, 7 days, 30 days post-explantation/transition, and at discharge.
All clinical data were collected, managed and analyzed by an independent data and statistical center and clinical monitoring unit to support safety/efficacy evaluation and market approval.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
EVAS TreatmentProcedure or surgery
Using interventional implantation of blood conduits into the left cardiac system, an extracorporeal pump shunts blood to the arterial system to partially or fully substitute cardiac pumping function and sustain systemic circulation.
| Study group | Role | What they receive |
|---|---|---|
| EVAS Treatment Group | Experimental | Not described Receives: Procedure: EVAS Treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.

Questions about this trial
What is this clinical trial studying?
A study testing EVAS Treatment in people with Cardiogenic Shock, run by China National Center for Cardiovascular Diseases at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 0 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 18 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact xianqiang wang (13331006960, wangxianqiang@fuwai.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Success rate of extracorporeal mechanical circulatory support using the investigational extracorporeal ventricular assist system (time frame: 30-day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Aug 2026.
