- 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 - 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 - NCT04823299Recruiting
Atrial fibrillation ablation using two different energy types
This trial tests whether one ablation approach works better than another for paroxysmal (intermittent) atrial fibrillation by targeting the heart’s “triggers” and “substrate” (where the rhythm problem is). If you qualify, you’ll be randomly assigned to one of two ablation energy methods during a pulmonary vein isolation procedure.
Ottawa, OntarioAges 18 years+ - NCT05610215Recruiting
Hybrid or catheter ablation for atrial fibrillation in hypertrophic heart
This trial compares two procedures to treat atrial fibrillation (an irregular heartbeat) in people who also have hypertrophic cardiomyopathy (thickened heart muscle). It looks at whether the hybrid approach or a catheter-based approach works better for controlling symptoms and heart rhythm.
BeijingAges 18 years+ - NCT06052098Recruiting
Comparing two ablation methods for early-stage lung cancer
This study compares two ways to destroy early-stage lung cancer without surgery: one using a needle through the chest (CT-guided) and another using a thin tube through the mouth (bronchoscopy-guided). It might be an option if you have small, outer-edge lung cancer and cannot or prefer not to have surgery.
Shanghai, Shanghai MunicipalityAges 18 years+ - 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 - NCT07141745Recruiting
Comparing energy types for repeat atrial fibrillation treatment
This trial compares two different energy methods (electroporation vs radiofrequency ablation) guided by 3D imaging for people who have had a prior ablation for atrial fibrillation but still have recurrences. It aims to find which method is safer and more effective for repeat procedures.
WroclawAges 18–85 - 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+ - NCT07601763Recruiting
Pulsed Field Ablation for Atrial Fibrillation Treatment
This trial tests a newer ablation technique called pulsed field ablation to treat atrial fibrillation, a heart rhythm disorder. The goal is to see if this method works well and is safe for patients who need treatment.
Beijing, Beijing MunicipalityAges 18 years+ - 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 - NCT07156877Recruiting
Balloon Catheter Ablation for Atrial Fibrillation
This study tests a new balloon catheter that uses pulsed electric fields to isolate the veins that carry blood from your lungs to your heart. It may be a treatment option for people with atrial fibrillation who are scheduled for an ablation procedure.
BrugesAges 18 years+ - NCT06647251Recruiting
Comparing different radiofrequency modes for atrial fibrillation ablation
This trial tests three different ways of delivering radiofrequency energy using a specific catheter (QDOT) during a first-time procedure to treat atrial fibrillation (AF), a type of irregular heartbeat. It aims to find which method works best for patients with recent or short-lasting AF episodes.
Paris, ParisAges 18 years+ - NCT06392932Recruiting
Esophageal temperature monitoring during heart ablation
This study tests a new way to monitor the temperature in your esophagus during a standard heart ablation procedure for atrial fibrillation. The goal is to see if the new catheter (Q-DOT Micro) safely heats the heart tissue without harming the esophagus.
Los Angeles, CaliforniaAges 18 years+ - NCT06711120Recruiting
Comparing two treatments for varicose veins in the lower legs
This study compares two minimally invasive treatments (radiofrequency ablation and microwave ablation) for varicose veins in the small saphenous vein. If your varicose veins cause symptoms like pain, swelling, or heaviness, this trial may help determine which treatment works better.
ChengduAges 18–90 - 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 - NCT07671898Recruiting
Freezing vs. Radiofrequency for Slow Heart Rate
This trial compares two procedures to treat very slow heart rates without needing a pacemaker. One uses freezing (cryoablation) and the other uses radiofrequency energy to target nerves that control heart rate.
Tomsk, Tomsk OblastAges 18–60 - 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+ - 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.

Compare two catheter approaches to treat ventricular tachycardia
This study compares an “outer heart” catheter approach (epicardial) versus an “inner heart” approach (endocardial-only) to treat a dangerous heart rhythm called ventricular tachycardia. It aims to see which approach works better and is safest for people with ischemic heart disease who are having their first ablation.

Common questions
- Are there clinical trials for radiofrequency catheter ablation?
- Yes. Clin2 currently lists 29 recruiting radiofrequency catheter ablation 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 radiofrequency catheter 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 radiofrequency catheter 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.
