This study tracks patients who have a minimally invasive procedure to close off a small pouch in the heart called the left atrial appendage. The procedure aims to reduce stroke risk, and this registry collects information about how patients do after the procedure.
Washington D.C., District of ColumbiaAges 18 years+ - NCT07441382Recruiting
Comparing treatments for frail older adults with atrial fibrillation
This study tests whether combining a heart procedure (catheter ablation) with a device to close the left atrial appendage (LAAO) is safer or better than blood thinners alone for frail patients 75 years or older with atrial fibrillation and high stroke risk. It aims to find a treatment that reduces stroke while lowering bleeding risks.
Guangzhou, GuangdongAges 75 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+ - 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 - 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+ - NCT07523620Recruiting
Heart rhythm procedure with left atrial appendage closure
This trial tests a procedure that closes off a small pouch in the heart (left atrial appendage) while also treating irregular heartbeat (atrial fibrillation) with a catheter ablation procedure. The goal is to reduce your stroke risk and treat your symptoms without needing blood thinners long-term.
Brussels, B CAP RAges 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+ - NCT07453940Enrolling by invitation
Closing off heart pouch with or without pulsed energy in atrial fibrillation
This study tests if adding a special energy treatment (pulsed field ablation) to a standard heart pouch closure is safe and works better for people with persistent atrial fibrillation who have few symptoms but a high risk of stroke.
Hangzhou, ZhejiangAges 18 years+ - NCT03642509Recruiting
Compare a heart procedure to blood-thinner pills for stroke prevention
This trial studies whether closing off part of the heart (the left atrial appendage) can prevent stroke as well as long-term newer blood-thinner pills. It may help people with atrial fibrillation who recently had a stroke or a warning stroke (TIA).
Aarhus, Central JutlandAges 18 years+ - 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 - NCT07125417RecruitingPhase 4
Blood thinner comparison after left atrial appendage closure
This study compares two approaches after a left atrial appendage closure (LAAC) procedure: taking no blood thinner versus taking just one antiplatelet medication. It aims to see which option is safer for people with atrial fibrillation who are at risk for bleeding.
Nagoya, Aichi-kenAges Any age - NCT07575867Recruiting
Reduced Blood Thinner Strategy After Heart Device Closure
This trial tests whether patients who receive a special device to close a hole in the heart (to prevent stroke from irregular heartbeat) can safely take fewer blood-thinning medications afterward. The study compares taking a standard blood thinner for 3 months versus taking aspirin only, to see which approach works best with fewer bleeding risks.
MoscowAges 18 years+ - NCT07360067Recruiting
Comparing two types of heart pacing for sick sinus syndrome
This study compares two different ways of placing a pacemaker lead to see which one better helps heart function and reduces future heart problems in people with sick sinus syndrome.
Seoul, SeoulAges 19 years+ - NCT04220047Recruiting
Surgery changes for preventing irregular heart rhythms during bypass
