About this study

Official title: Evaluation of the Safety and Effectiveness of a Percutaneously Created Interatrial Shunt to Alleviate Heart Failure Symptoms in Patients With Chronic Heart Failure and Preserved or Mid-Range Left Ventricular Ejection Fraction

Patients with heart failure and preserved left ventricular ejection fraction (HFpEF, EF ≥ 50%) or mid-range left ventricular ejection fraction (HFmrEF, 40% < EF < 50%) 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

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.

  1. The composite incidence of one or more major adverse cardiac, cerebrovascular and thromboembolic events and change in supine exercise PCWP at peak exercise.

    Defined as cardiovascular death, embolic stroke, embolic myocardial infarction, pulmonary or arterial embolism, device-and/or procedure-related serious adverse cardiac events.

    Measured: At 1 month and through 12 months

Questions about this trial

What is this clinical trial studying?

A study testing ALV1 System in people with Heart Failure, run by Alleviant Medical, Inc. at 5 sites in 4 countries.

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 11 inclusion and 21 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 4 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Australia, Canada, New Zealand, Sweden. 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?

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 major adverse cardiac, cerebrovascular and thromboembolic events and change in supine exercise PCWP at peak exercise. (time frame: At 1 month and through 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04838353, which also lists 2 linked publications.

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 4 Oct 2024; AzTrials last refreshed its copy on 27 Oct 2026.
