Recruiting studies
- NCT06099106Recruiting
Testing a new device to close the left atrial appendage in AFib
This trial tests a new device called ENDOMATIC SEPIOLA that closes a small pouch in your heart (the left atrial appendage) to lower your stroke risk. It is a non-surgical option for people with atrial fibrillation who cannot take blood thinners.
TbilisiAges 18 years+ - NCT06620757Recruiting
Short-term single blood thinner after LAmbre device implant
This study tests whether it is safe and effective to use just one blood thinner (aspirin or clopidogrel) for a short time after getting a LAmbre device implanted to close off a heart pouch that can cause strokes. It is for people with atrial fibrillation who cannot take standard blood thinners long-term.
A CoruñaAges 18–100 - NCT06061757Recruiting
Combining 4D-ICE and TEE imaging for heart closure
This trial tests a new imaging method (4D-ICE) used alongside a standard ultrasound (TEE) during a heart procedure to close the left atrial appendage, a small pouch in the heart where clots can form in people with atrial fibrillation. The goal is to see if the new method makes the procedure safer and more precise.
Overland Park, KansasAges 18–80 - NCT06075628Recruiting
CT scan study after LAA closure procedure
This study looks at long-term outcomes after LAA closure (a procedure to reduce stroke risk) by reviewing CT scans of the device. It aims to learn if blood flow around the device affects healing and future health.
Overland Park, KansasAges 18 years+ - NCT06405750Recruiting
Study of the left atrial appendage during open-heart surgery
This study looks at a part of the heart called the left atrial appendage during open-heart surgery. It aims to learn more about heart rhythm problems and blood clots, which may help improve future treatments.
CopenhagenAges 18 years+ - NCT06348394Recruiting
Comparing heart imaging methods for a procedure to prevent stroke
This trial is testing two ways to guide a procedure that closes a small pouch in the heart to lower the risk of stroke in people with atrial fibrillation. The goal is to see if one method is as good or better than the other.
Plano, TexasAges 18–90 - NCT06007872Recruiting
Heart device implant using ultrasound probe inside the heart
This trial studies a procedure to implant a Watchman device using a tiny ultrasound probe placed inside the heart, avoiding a probe in the throat. It may help patients with atrial fibrillation who need to reduce stroke risk.
Cleveland, OhioAges 18 years+ - NCT05976685Recruiting
Close the left atrial appendage after stroke despite blood thinners
This study tests whether closing a heart pouch called the left atrial appendage can prevent future strokes in people with atrial fibrillation who had an ischemic stroke even while taking blood thinners. It may help reduce stroke risk by blocking a common place where clotting can start.
BrugesAges 18 years+ - NCT05963698Recruiting
Closing off a heart pouch to prevent stroke
This study tests a procedure that seals off the left atrial appendage (a small heart pouch) to help prevent stroke in people with atrial fibrillation. You may be considered if your stroke risk is high and you are already on blood-thinner medicine.
Birmingham, AlabamaAges 18 years+ - NCT05565209Recruiting
Registry for closing the left atrial appendage
This study is a hospital registry that collects information from people who are having a device placed to close a part of the heart called the left atrial appendage. It helps doctors understand how this procedure works in real life, including different outcomes.
CréteilAges 18 years+ - NCT05257954Recruiting
Testing frailty in people getting a left atrial appendage closure
This study looks at frailty (how strong or vulnerable a person is) in adults who are having a left atrial appendage closure procedure through a catheter. The goal is to understand which patients may be more vulnerable during or after the procedure.
Québec, QuebecAges 18 years+ - NCT04796714RecruitingPhase 4
Aspirin and clopidogrel after left heart appendix closure
This trial studies a “double anti-platelet” medicine plan (aspirin plus clopidogrel) after closing the left atrial appendage, a procedure used to reduce stroke risk in some heart rhythm conditions. It aims to find a safer, better medicine strategy for people who cannot take standard blood thinners.
PessacAges 18 years+ - NCT03243175RecruitingPhase 3
Avoiding blood thinners after brain bleeding in atrial fibrillation
This Phase 3 trial studies whether it’s safer to avoid long-term blood thinners after a spontaneous brain bleed in people with atrial fibrillation (an irregular heart rhythm). It compares different prevention strategies to lower the risk of stroke or other blood-vessel problems without causing new, serious bleeding.
LilleAges 18 years+ - NCT07620262Recruiting
Combined atrial fibrillation treatment and stroke prevention study
This study tests a new approach for people with atrial fibrillation (a type of irregular heartbeat) who are also at high risk for stroke. It combines a procedure to fix the heart's electrical signals with closing off a small pouch in the heart to reduce stroke risk, potentially avoiding long-term blood thinners.
Bay Shore, New YorkAges 18 years+ - NCT06212674RecruitingPhase 4
Stroke prevention: combined heart procedure for atrial fibrillation
This study tests a combined approach — a catheter ablation to fix the irregular heartbeat (atrial fibrillation) and a device to close the left atrial appendage — in people who recently had a stroke caused by a clot. The goal is to prevent future strokes and reduce the need for long-term blood thinners.
Katowice, Upper SilesiaAges 18–75 - NCT04240366Recruiting
Extra left atrial appendage treatment during AF ablation
This trial tests whether adding treatment to the left atrial appendage during a standard catheter ablation helps people with persistent atrial fibrillation (AF). It may improve how well AF is controlled, but you must meet specific heart rhythm and heart scan measurements to join.
Hamburg, Free and Hanseatic City of HamburgAges 18 years+ - NCT04298723Recruiting
Left atrial appendage closure vs blood thinners after brain bleed
This trial compares a procedure that blocks a heart blood-choke point (the left atrial appendage) versus taking blood thinners by mouth. It is for people with atrial fibrillation who have had a brain bleed and may be safer avoiding long-term blood thinners.
Mannheim, Baden-WurttembergAges 18 years+ - NCT06548269Recruiting
Assessing stroke recovery in patients with atrial fibrillation
This study watches how people recover from a recent stroke caused by a heart rhythm problem called atrial fibrillation (or AFib). It aims to find better ways to predict recovery and guide future care.
Jinan, ShandongAges 18 years+ - NCT05164107Recruiting
Test a new pulsed-field catheter procedure for atrial fibrillation
This trial tests a new pulsed-field device used during an atrial fibrillation (AF) catheter ablation, aiming to improve safety and effectiveness. It’s for people who have AF and are planning an AF ablation procedure.

Common questions
- Are there clinical trials for left atrial appendage closure?
- Yes. Clin2 currently lists 43 recruiting left atrial appendage closure studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a left atrial appendage closure trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a left atrial appendage closure trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
