Recruiting studies
- NCT02138695Recruiting
Study of outcomes after atrial fibrillation catheter ablation
This study follows people after a procedure called catheter ablation to treat atrial fibrillation (an irregular heart rhythm). It aims to learn which factors help predict outcomes, so future care can be better tailored.
SeoulAges 19 years+ - NCT05311137Recruiting
Closed-loop monitoring for atrial fibrillation
This study tests a “closed-loop” approach to treating atrial fibrillation, meaning the care plan may adjust based on how you’re doing. It may help improve how heart rhythm problems are managed over time.
Shanghai, Shanghai MunicipalityAges 18–100 - NCT02558699Recruiting
Virtual mapping guided catheter ablation for atrial fibrillation
This trial tests whether a “virtual” computer map created from your heart scans can help doctors do catheter ablation to treat atrial fibrillation (AF). It aims to improve the procedure for people whose AF symptoms were not controlled well with anti-arrhythmia medicines.
SeoulAges 19–80 - 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 - NCT05508256RecruitingPhase 4
Ablation for atrial fibrillation in heart failure with preserved function
This trial tests whether a catheter procedure that treats atrial fibrillation works better than standard care for people with heart failure with preserved ejection fraction. It aims to improve heart rhythm symptoms and overall outcomes compared with conventional treatment.
BerlinAges 18 years+ - NCT04997824Recruiting
AI-guided selection for atrial fibrillation ablation
This trial tests whether an artificial intelligence (AI) system can help choose the best patients for a procedure called catheter ablation for atrial fibrillation (AF). It may improve which people benefit most while keeping safety in mind.
SeoulAges Any age - 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 - NCT05961865Recruiting
Study of inflammation during catheter ablation for atrial fibrillation
This study measures changes in inflammation in people with atrial fibrillation (AF) who are getting a catheter ablation procedure. It may help doctors better understand what happens in the body during the procedure and why some patients do better than others.
MilanAges 18–85 - NCT05539040Recruiting
Testing why certain heart signals trigger atrial fibrillation
This trial studies abnormal electrical signals in the right upper heart chamber and how they relate to atrial fibrillation (AF). It may help improve how doctors target AF treatment during catheter ablation for people who have AF symptoms.
LondonAges 18–85 - NCT06125925Recruiting
Ablation for AFib in patients with heart failure and preserved ejection fraction
This study tests whether a catheter ablation procedure can help people with atrial fibrillation and a kind of heart failure where the heart pumps normally but doesn't relax properly (HFpEF). It looks at whether the procedure can improve symptoms and heart function.
NanjingAges 18–80 - NCT04715425Recruiting
Surgery vs catheter procedure for persistent atrial fibrillation
This trial compares two ways to treat persistent atrial fibrillation: a minimally invasive surgery approach versus a catheter ablation. It may help people find the most effective option to reduce ongoing abnormal heart rhythm and avoid repeat procedures.
AmsterdamAges 18–80 - NCT06249347Recruiting
New ablation approach for persistent atrial fibrillation with stroke risk
This trial tests a new type of catheter ablation (using heat to create scar lines in the heart) for people with persistent atrial fibrillation who have a higher risk of stroke or bleeding. It aims to see if this approach can help prevent strokes and reduce the need for long-term blood thinners.
Wenzhou, ZhejiangAges 18 years+ - 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+ - NCT07857044Recruiting
Left atrial fibrosis in persistent atrial fibrillation study
This study looks at how scar tissue in the heart's upper chambers relates to other health issues in people with persistent atrial fibrillation. It aims to improve understanding and treatment for this condition.
Augsburg, BavariaAges 18 years+ - NCT06145906Recruiting
Optimizing catheter ablation for atrial fibrillation
This trial is studying a way to improve the entire process of catheter ablation for atrial fibrillation. It may help people who are having this procedure for the first time and have a normal-sized left atrium and good heart function.
Zhengzhou, HenanAges 18–80 - NCT06333327Recruiting
Atrial fibrillation ablation with a balloon catheter registry
This study is collecting data on people having a procedure called catheter ablation for atrial fibrillation using a special radiofrequency balloon. The goal is to see how well it works and to help improve future treatments.
BrusselsAges 18–85 - NCT06363604Recruiting
Alcohol injection with ablation for persistent atrial fibrillation
This trial is testing a new approach to treat persistent atrial fibrillation (a type of irregular heartbeat) by combining standard catheter ablation with a special injection of alcohol (ethanol) into certain heart veins. It may help people whose symptoms haven't improved with medication.
Shanghai, Shanghai MunicipalityAges 18–85 - NCT06402617Recruiting
Ablation of active spots in atrial fibrillation
This trial is testing a new way to treat atrial fibrillation by using a catheter to target the specific areas in the heart that trigger the irregular heartbeat. If you have persistent atrial fibrillation and haven't had prior catheter ablation, you may be eligible to join.
LondonAges 18–85 - NCT07852221Recruiting
Pace and ablate for atrial fibrillation
This study looks at how well a treatment called 'pace and ablate' works for people with atrial fibrillation. It involves using a pacemaker or similar device to control the heart rate, and it aims to see who benefits most and how they do over time.
ZabrzeAges 18 years+ - NCT03355456Recruiting
Catheter ablation for atrial fibrillation with low-voltage mapping
This trial studies a catheter procedure that targets areas in the heart that show low electrical voltage to treat atrial fibrillation (an irregular heartbeat). You may be eligible if you have non-paroxysmal atrial fibrillation, have tried heart rhythm medicines, and your scan shows low-voltage areas in the left atrium.
Cleveland, OhioAges 18–85 - NCT05978388Recruiting
CT scan before catheter ablation for atrial fibrillation
This trial is testing whether a coronary CT angiography scan, performed before catheter ablation for atrial fibrillation, helps doctors find hidden blockages in heart arteries. It may help people without known heart disease avoid unnecessary procedures.
Hellerup, Capital RegionAges 18 years+ - NCT07809347Recruiting
Factors linked to slow heart rate after pulsed field ablation
This study looks at why some people have a slower heart rate after a heart procedure called pulmonary vein isolation using pulsed field ablation (PFA). It aims to find out what factors might make this more likely, which could help doctors predict and manage it better.

The software analyzes heart signals during the ablation to guide treatment, potentially improving outcomes for people whose condition is more complex.
AvignonAges 18 years+ - NCT07799519RecruitingPhase 2

- How do I know if I qualify for a atrial fibrillation ablation 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 atrial fibrillation ablation 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.
