About this study
Official title: Evaluation of the Safety and Feasibility of a Percutaneously Created Interatrial Shunt to Alleviate Heart Failure Symptoms in Patients With Chronic Heart Failure and Reduced Left Ventricular Ejection Fraction
Patients with heart failure and reduced left ventricular ejection fraction (HFrEF, EF ≤ 40%) with mild to moderate functional limitation will be evaluated for treatment via creation of a no-implant interatrial shunt using clinical, echocardiographic, and invasive hemodynamic data.

- Heart Failure

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ALV1 SystemDevice
The ALV1 system is designed to create a controlled size interatrial shunt via a proprietary intra-cardiac catheter. There is no temporary or permanent implant used to create or maintain the interatrial shunt. The therapy is intended to be delivered in a single procedure administered under general anesthesia in a cardiac catheterization laboratory.
What is being measured
The primary outcome is the main question the study is designed to answer.
The composite incidence of one or more of the following through the 1-month follow-up visit: major adverse cardiac, cerebrovascular and thromboembolic events.
Measured: 1-Month

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing ALV1 System in people with Heart Failure, run by Alleviant Medical, Inc. at 1 site in Georgia.
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 4 inclusion and 28 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: finished, as of the sponsor's last update on 18 Jul 2023. 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 Georgia. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The composite incidence of one or more of the following through the 1-month follow-up visit: major adverse cardiac, cerebrovascular and thromboembolic events. (time frame: 1-Month). 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 Jul 2023; AzTrials last refreshed its copy on 27 Oct 2026.
