Plain-language summary
The primary objective is to demonstrate the safety and efficacy of the implantation of the LAmbre PlusTM device in patients with large or irregularly shaped appendages with non-valvular atrial fibrillation who are at increased risk for stroke and systemic embolism compared to oral anticoagulation (OAC).

Inclusion criteria
. The patient is a male or non-pregnant female ≥18 years of age
. The patient has documented paroxysmal, persistent, or permanent non-valvular atrial fibrillation or flutter
. The patient has a CHADS2 score ≥ 2 or a CHA2DS2-VASc score of ≥ 3, and is recommended for oral anticoagulation therapy
. The patient is deemed by their physician to be suitable for short-term OAC, but there is an appropriate rationale for seeking a non-pharmacologic alternative to oral anticoagulation
. The patient is deemed suitable for LAA closure in a shared decision model with a non-implanting physician
. The patient is willing and able to comply with protocol-specified treatment and follow-up evaluations
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Composite of time to first occurrence of stroke, cardiovascular death, or clinically relevant major or non-major bleeding events
Timeframe: through study completion, up to 5 years
2
Composite of time to first occurrence of ischemic stroke or systemic embolism
Timeframe: through study completion, up to of 5 years
. 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
. Pregnant or nursing patients and those who plan pregnancy in the period up to 1 year following index procedure. Female patients of childbearing potential must have a negative pregnancy test done within 7 days prior to index procedure per site standard test
. 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)
. Patients who require long-term anticoagulation/DAPT for a condition other than atrial fibrillation
. Patients not suitable for short term oral anti-coagulation (including due to bleeding diathesis or coagulopathy or absolute contraindication to OAC or DAPT ) or who will refuse transfusion
. Patients with rheumatic mitral valve disease, known severe aortic stenosis requiring surgical or percutaneous valve replacement, or existing mechanical valve prosthesis
. Active infection with bacteremia
. Known hypersensitivity or contraindication to aspirin, clopidogrel, heparin/bivalirudin, any device material or component (nitinol, nickel, titanium, PET), and/or contrast sensitivity that cannot be adequately pre-medicated
. Anatomic conditions that would prevent performance of the LAA occlusion procedure (e.g., prior atrial septal defect \[ASD\] or patient foramen ovale \[PFO\] surgical repair or implanted closure device, or obliterated left atrial appendage)
