About this study

Official title: DRAIN-HF: Diuretics Alone vs. Aortix Endovascular Device for Acute Heart Failure

Aortix is a circulatory support device for chronic heart failure patients on medical management who have been hospitalized for acute decompensated heart failure (ADHF) and have persistent congestion despite usual medical therapy.

Eligible ADHF patients with diuretic resistance (irrespective of ejection fraction) will be enrolled and randomized 1:1 to either the Aortix system or standard of care medical management.

Read the detailed description

The study is a prospective, multi-center, randomized, nonblinded study to evaluate the safety and effectiveness of the Aortix System versus standard of care medical therapy in patients hospitalized with acute decompensated heart failure (ADHF) and persistent congestion despite usual medical management.Eligible ADHF patients with diuretic resistance (irrespective of ejection fraction) will be enrolled and randomized 1:1 to either the Aortix system or standard of care medical management. Randomization will be stratified by ejection fraction..

An additional registry arm will enroll patients who are considered candidates for advanced therapies in the near-term, but need improvement in their renal function to be able to receive additional medical therapies. All eligible enrolled registry subjects will receive Aortix system support.

Planned study population is male or female patients 21 years of age or greater, with acute decompensated heart failure and diuretic resistance who remain congested despite standard of care medical therapy.

This study will enroll up to 320 subjects with heart failure at 50 clinical sites in the United States and up to 5 OUS sites. The randomized study includes up to 240 subjects and the Advanced HF registry includes up to 80 subjects.

Questions about this trial

What is this clinical trial studying?

A study testing Aortix System in people with Heart Failure and Cardiorenal Syndrome, run by Procyrion at 50 sites in 2 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 12 inclusion and 69 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 25 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 50 sites in United States, Hungary. 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 Rubi Reyes-Fuentez (832-536-1601, rubi@procyrion.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Safety Endpoint: Incidence of Aortix Device / Procedural-Related Major Adverse Events (MAE) through 30 days of Follow-up. (time frame: Baseline to 30 day Follow-Up). The study lists 2 primary outcomes in all. 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 25 Aug 2026.
