Recruiting studies
- 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 - 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+ - 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 - 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 - 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 - 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+ - NCT04148625Enrolling by invitation
Sub-xiphoid hybrid maze for persistent atrial fibrillation after failed ablation
This trial studies a hybrid heart procedure to treat persistent atrial fibrillation in people whose previous catheter ablation did not work. It aims to improve heart rhythm and reduce ongoing symptoms by using a planned combination of techniques and careful follow-up.
Ages 18–80 - NCT07630857Recruiting
Heart Mapping to Personalize Atrial Fibrillation Treatment
This trial tests a new way to map the heart's electrical signals to help doctors better target and treat atrial fibrillation (an irregular heartbeat). If you're having a procedure to treat AF, this study may help improve the success of your treatment.
Beijing, Beijing MunicipalityAges 18–80 - 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+ - NCT04606693Recruiting
Screening for sleep apnea before heart rhythm ablation
This study looks at whether checking for sleep apnea (breathing pauses during sleep) and treating it helps people prepare for atrial fibrillation ablation. It may help by improving outcomes for patients with atrial fibrillation who keep having episodes despite medication.
Madrid, MadridAges 18 years+ - NCT05723926Recruiting
Carotid implants to help prevent stroke repeat in atrial fibrillation
This trial tests whether placing a carotid implant can reduce the chance of having another stroke in people with atrial fibrillation who are already taking blood thinners. It aims to prevent stroke recurrence while you continue prescribed anticoagulation.
Rockford, IllinoisAges 18 years+ - NCT04045665RecruitingPhase 3
Blood thinner vs usual care for new heart rhythm after bypass surgery
This trial tests whether using a blood thinner in people with new, temporary atrial fibrillation after CABG (heart bypass surgery) can reduce harmful outcomes compared with standard treatment. It may help prevent stroke or other complications if your rhythm problem fits the trial’s timing and risk profile.
Little Rock, ArkansasAges 18 years+ - NCT07518966Recruiting
Heart Rhythm Treatment Success Tracking Study
This study follows patients getting a newer heart rhythm treatment called pulsed field ablation for atrial fibrillation (an irregular heartbeat). Researchers want to understand which patients do well long-term and which may need additional treatment.
Chengdu, SichuanAges 18 years+ - NCT06199180Recruiting
Comparing two ablation methods for repeat atrial fibrillation treatment
This trial tests a newer type of energy (pulsed field ablation) against the standard heat-based method (radiofrequency) for people who have already had one ablation and now have atrial fibrillation again. The goal is to see which works better for keeping your heart in a normal rhythm.
GroningenAges 18–80 - NCT06253000Recruiting
Heat vs. Freezing for the Back of the Heart
This trial tests two ways to treat the back wall of the heart's left chamber in people with stubborn atrial fibrillation. It compares radiofrequency (heat) and cryoablation (freezing) to see which is safer and works better.
MoscowAges 18–80 - NCT07275697RecruitingPhase 4
Weight loss drug and heart ablation study for AFib
This trial tests whether a weight loss medication (semaglutide) given before and after a first-time heart ablation procedure for atrial fibrillation can improve outcomes. It is for people who are overweight or obese and have certain related health conditions.
StockholmAges 18 years+ - NCT05378308Recruiting
Tracking blood thinner use in people with AF or blood clots
This registry study looks at how people with atrial fibrillation (AF) or blood clots (VTE) use blood thinners, especially NOACs, over time. It may help doctors better understand real-world patterns of treatment and outcomes.
Zhengzhou, HenanAges Any age - NCT07018596Recruiting
New pulsed field ablation for paroxysmal atrial fibrillation
This trial tests a new type of heart procedure that uses gentle electrical pulses to fix abnormal signals in the upper chambers of the heart for people with a specific type of atrial fibrillation that comes and goes on its own. It may be an option if your AFib episodes stop within 7 days and medications haven't helped enough.
Prague, RoentgenovaAges 18–85 - NCT05029115Enrolling by invitation
SGLT2 pill study for atrial fibrillation with type 2 diabetes
This trial tests whether an SGLT2 inhibitor pill can help people who have atrial fibrillation (an irregular heartbeat) and type 2 diabetes. You may be eligible if you’re in the right age range, on diabetes pills only, and meet specific heart and lab criteria.
Yangcheon, SeoulAges 20–80 - NCT07671677Recruiting
BodyGuardian monitoring after AF ablation
This study tests using a portable heart monitor called BodyGuardian to check for atrial fibrillation returning after a procedure called ablation. It may help your doctor find irregular heartbeats early.
Delray Beach, FloridaAges 18 years+ - NCT07122947Recruiting
