New heart plug aims to cut stroke risk without blood thinners
NCT ID NCT07385599
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tests a new device called the LAmbre™ II, designed to close off a small pouch in the heart (the left atrial appendage) in people with atrial fibrillation who are at high risk for stroke. The goal is to prevent blood clots from forming there, potentially reducing stroke risk without needing lifelong blood thinners. Only 10 participants will be enrolled to check if the device is safe and works as intended.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- LAmbre™ II left atrial appendage occluder device
- What this could lead to
- If successful, this device could offer a way to lower stroke risk in atrial fibrillation patients without needing lifelong blood-thinning medication.
- What could go wrong
- This is a very early, small study with only 10 participants, so results may not apply broadly. There are risks like heart injury, device movement, or stroke during or shortly after the procedure.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. The patient age ≥18 years; 2. The patient has documented paroxysmal, persistent, or permanent non-valvular atrial fibrillation; 3. The patient has a CHA2DS2-VASc score of ≥ 2 in men and CHA2DS2-VASc score of ≥ 3 in women; 4. The patient is recommended for oral anticoagulation therapy, but there is an appropriate rationale for seeking a non-pharmacologic alternative to oral anticoagulation; 5. The patient is deemed suitable for LAA closure by the site investigator and a clinician not a part of the procedural team in the shared decision-making process, and this determination has been documented in the patient's medical record; 6. The patient is willing and able to comply with the required medication post-procedure and follow-up evaluations; 7. The patient (or his or her legally authorized representative) has been informed of the nature of the study, agrees to its provisions, and has been provided written informed consent approved by the appropriate Institutional Review Board (IRB) or Ethics Committee (EC) Exclusion Criteria: 1. Pregnant or nursing patients and those who plan pregnancy during the study period. Female patients of childbearing potential must have a negative pregnancy test (per site standard test) within 7 days prior to the index procedure; 2. Patients with atrial fibrillation that is defined by a single occurrence, or that is transient or reversible (e.g., secondary to CABG, an interventional procedure, pneumonia, or hyperthyroidism); 3. Patients who require long-term anticoagulation for a condition other than atrial fibrillation; 4. Bleeding diathesis or coagulopathy; 5. Patients with rheumatic mitral valve disease, known severe mitral stenosis requiring surgical or percutaneous valve replacement, or existing mechanical valve prosthesis; 6. Active infection with bacteremia; 7. Known hypersensitivity or contraindication to aspirin, clopidogrel, heparin, any device material or component (nickel titanium, PET, polypropylene), and/or contrast sensitivity; 8. Prior atrial septal defect (ASD) or patient foramen ovale (PFO) surgical repair or implantation of closure device; 9. Left atrial appendage is obliterated and surgical ligated; 10. Underwent any cardiac or non-cardiac interventional or surgical procedure within 30 days prior to the procedure or planned to have the interventional or surgical procedure within 60 days after implant procedure (e.g., cardioversion, ablation, percutaneous coronary intervention, cataract surgery, etc.); 11. Recent (within 90 days prior to procedure) stroke, transient ischemic attack, or myocardial infarction; 12. New York Heart Association Class IV; 13. Patients with severe renal failure (estimated glomerular filtration rate\<30 ml/min/1.73m2); 14. Known asymptomatic carotid artery disease with\>70% diameter stenosis OR symptomatic carotid disease (\>50% diameter stenosis with ipsilateral stroke or TIA). Subjects with prior carotid endarterectomy or carotid stent placement may be enrolled, provided that known diameter stenosis is \<50%; 15. Life expectancy is less than 1 year; 16. Current participation in another investigational drug or device study.
