An observational study in Heart Failure, sponsored by CVRx, Inc.. Recruiting at 30 sites in 2 countries. Per ClinicalTrials.gov, last updated 2026-09-11.
Sponsored by CVRx, Inc. · Observational
The purpose of this registry (NCT02880618) is to evaluate the effect of BAROSTIM THERAPY with the BAROSTIM NEO System in the commercial setting in subjects recently implanted under the CE-Marked indication for heart failure with reduced ejection fraction (HFrEF).
Summary:
The CVRx BAROSTIM THERAPY in Heart Failure with Reduced Ejection Fraction (HFrEF) Registry will be performed with subjects who have been recently implanted with the BAROSTIM NEO System in accordance with CE-Mark approved criteria for heart failure. Subjects must be enrolled within 30 days from implant. Up to 500 subjects will be enrolled at up to 50 sites. Data should be obtained from standard of care measurements taken prior to implant, at enrollment/baseline, and at 3, 6, and 12 months after the device was implanted, at which time each subject will be exited from the registry.
Eligibility:
Subjects can be included in the Heart Failure with Reduced Ejection Fraction Registry if they were implanted in the past 30 days and meet the CE-Mark approved indications, and are not contraindicated, for the BAROSTIM NEO System in the treatment of heart failure. The BAROSTIM NEO System is indicated for subjects with heart failure, defined as New York Heart Association (NYHA) functional Class III and left ventricular ejection fraction (LVEF) ≤ 35% despite being treated with the appropriate heart failure guideline directed therapy.
The contraindications are:
Objectives:
To describe change in the following measures at 3, 6 and 12 months compared to pre-implant baseline:
Evaluate health care utilization over follow-up, such as heart failure hospitalizations.
Describe device programming and utilization

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
