Exercise program to improve symptoms in atrial fibrillation and heart failure
This study tests if starting a supervised exercise program can help older adults with both atrial fibrillation and a type of heart failure called HFpEF feel better and have a better quality of life. You'll be asked to join exercise sessions and have regular check-ins to see how you're doing.
Chicago, IllinoisAges 60–99 - NCT06523738Recruiting
Studying heart size changes after shock and ablation for AF
This trial looks at how the size of your heart's upper-left chamber (left atrium) changes after a procedure to restore a normal rhythm (cardioversion). It aims to see if these changes can predict whether atrial fibrillation (AF) will come back after a later procedure called radiofrequency ablation.
Chongqing, Chongqing MunicipalityAges 18 years+ - NCT04432220RecruitingPhase 4
Taking blood thinners one year after atrial fibrillation ablation
This study looks at whether people who have stayed in normal rhythm one year after atrial fibrillation ablation should continue blood thinning treatment. It may help guide safer, more personalized choices about long-term blood thinners after a successful procedure.
SeoulAges 19–80 - NCT07217067RecruitingPhase 2
Study of PKN605 for people with atrial fibrillation
This trial tests a new medicine called PKN605 for people with atrial fibrillation (irregular heartbeat). The goal is to see if it can safely help control heart rhythm. You will need to have had at least two AF episodes recently and meet other heart health criteria.
Tupelo, MississippiAges 18 years+ - NCT07728539Recruiting
Comparing a faster ablation method for atrial fibrillation
This study compares a newer, faster type of ablation (high-power short-duration) with the standard approach for treating atrial fibrillation. The goal is to see which method is safer and more effective at restoring a normal heart rhythm.
MoscowAges 18–70 - NCT04529785Recruiting
Tested added ethanol vein treatment during repeat atrial fibrillation ablation
This trial compares two ways to help stop atrial fibrillation during a repeat procedure: standard vein isolation only versus standard isolation plus an added medicine (ethanol) into the vein of Marshall. It aims to see whether the added step improves results when atrial fibrillation returns after a previous successful treatment.
Bruges, Please SelectAges 18 years+ - NCT04696081Recruiting
Atrial fibrillation treatment in people with active cancer
This trial studies atrial fibrillation (an irregular heartbeat) in adults who have active cancer. It looks at people whose atrial fibrillation started after their cancer diagnosis or returned after cancer diagnosis.
Caen, NormandyAges 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+ - NCT05115214Recruiting
Device test for treating irregular heartbeat with AF ablation
This trial studies a heart procedure using the Affera SpherePVI system to treat paroxysmal (comes and goes) or persistent atrial fibrillation. It’s for people who still have symptoms despite at least one anti-arrhythmia medicine, and who are good candidates for catheter ablation.
PragueAges 18–75 - NCT05144503Recruiting
Test of a new catheter procedure for irregular heart rhythm
This study checks how safe and effective a special catheter procedure (SpherePVI) is for treating paroxysmal (comes and goes) or persistent atrial fibrillation. You may be considered if your atrial fibrillation keeps returning and you’ve already tried at least one medication but it didn’t work or you couldn’t tolerate it.
VilniusAges 18–75 - NCT05266144Recruiting
Catheter ablation for non-valvular atrial fibrillation
This trial studies catheter ablation, a procedure that targets heart rhythm triggers, for people with atrial fibrillation (an irregular heartbeat). It may help improve rhythm control, but you must meet specific heart and testing requirements and avoid certain conditions.
Beijing, Beijing MunicipalityAges 18–80 - NCT05638841Recruiting
Study of repeat atrial fibrillation risk after ablation
This study follows adults who have had a procedure to treat an irregular heartbeat, to understand who is more likely to have it return. It may help doctors predict risk and plan follow-up after the procedure.
BeijingAges 18 years+ - NCT05776797Recruiting
Ablation vs best medicines for CRT patients with permanent atrial fibrillation
This trial compares two approaches—an AV junction ablation procedure versus continued best medical treatment—in people who already have a heart device for heart failure (CRT) but still have ongoing permanent atrial fibrillation. It aims to improve how well your heart rhythm is controlled and how effectively the device can pace your heart.
Liberec, Liberec RegionAges 18–85 - NCT05872776Recruiting
Home ECG monitoring to reduce atrial fibrillation episodes
This trial uses a home heart monitor (a chest patch with an ECG) to study how atrial fibrillation (an irregular heartbeat) changes over time and how this may help manage symptoms. You may be included if you have a documented, short-lasting type of atrial fibrillation and a moderate amount of AF seen on a 14-day heart recording.
Tel AvivAges 18–85 - NCT05890664RecruitingPhase 3
Colchicine after shock treatment to stop atrial fibrillation
This trial tests whether colchicine given after cardioversion (a procedure that restores normal rhythm) helps keep the heart in normal rhythm afterward. It may help some people have fewer early returns of atrial fibrillation.
Bruderholz, Basel-LandschaftAges 18 years+ - NCT06322017Recruiting
Early vein isolation for atrial fibrillation in older adults
This study compares doing vein isolation soon after diagnosis versus usual care in people 75+ with new or early atrial fibrillation. The goal is to see if early treatment prevents the condition from getting worse and improves quality of life.
Nantes, Loire AtlantiqueAges 75 years+ - NCT06528262RecruitingPhase 4
Study of enavogliflozin to prevent atrial fibrillation return after heart ablation
This trial tests if enavogliflozin, a diabetes drug, can help prevent atrial fibrillation (an irregular heartbeat) from coming back after a catheter ablation procedure in people with heart failure. If you've recently had or are planning this procedure, this study may offer a new way to keep your heart rhythm steady.
SeoulAges 19–84 - NCT06556732RecruitingPhase 1
Eplerenone for preventing atrial fibrillation return
This trial is testing whether a medication called eplerenone can help prevent atrial fibrillation (AF) from coming back in people who have structural heart disease and have already had their heart rhythm restored to normal. It may be a good option if you are looking for a way to keep your heart in a normal rhythm.
AsyutAges 20–70 - NCT06615596RecruitingEarly Phase 1
Stopping blood thinners after successful atrial fibrillation ablation
This trial tests whether it is safe to stop taking blood thinners (anticoagulants) after a successful ablation procedure for atrial fibrillation. If you have had no AF for 3 months after your first ablation, you may be able to stop these medications, reducing your risk of bleeding.
Boston, MassachusettsAges 18 years+ - NCT06696170Recruiting
New catheter for atrial fibrillation using nanosecond pulses
This trial tests a new catheter that uses very short electrical pulses to treat atrial fibrillation (a type of irregular heartbeat). It may help people whose AF symptoms continue despite medication.
HasseltAges 18–75 - NCT06784466Recruiting
New ablation procedure for atrial fibrillation
This study is testing a new type of ablation procedure for atrial fibrillation (an irregular heart rhythm). It uses special energy to create scar tissue in the heart to block faulty electrical signals. If you have AF that isn’t controlled by medication, you may qualify.
Birmingham, AlabamaAges 18–80 - NCT06871228Recruiting
Stopping blood thinners after successful AF ablation with close heart monitoring
This trial tests whether people with atrial fibrillation who have had a successful ablation procedure can safely stop taking blood thinners (NOACs) if they wear a monitor to check for any silent heart rhythm problems. It may help you avoid the risks of long-term blood thinner use if your ablation has been effective.
Hefei, AnhuiAges 18–80 - NCT06954610Recruiting
