ZagrebAges 18 years+ - NCT04088071Recruiting
Ablation for heart rhythm problems using a specific technology
This study looks at how well catheter ablation works for treating certain heart rhythm disorders (like atrial fibrillation or ventricular arrhythmias) using a specific brand of catheters. The aim is to gather real-world data to better understand the procedure's outcomes.
Birmingham, AlabamaAges 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 - NCT07316270Recruiting
Catheter ablation for atrial fibrillation after brain bleeding
This trial studies a procedure called catheter ablation to treat atrial fibrillation (an irregular heartbeat) in people who have had a brain hemorrhage. The procedure aims to reduce stroke risk and improve heart rhythm without increasing bleeding risk.
Hefei, AnhuiAges 18 years+ - 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+ - NCT07445334Recruiting
Catheter ablation vs. medications for frequent extra heartbeats
This study compares two ways to treat premature ventricular contractions (extra heartbeats that can cause symptoms). One approach is a catheter ablation (a procedure that destroys the tissue causing the extra beats), and the other is using anti-arrhythmic drugs (medications to control the rhythm). If you have frequent PVCs and a healthy heart, this trial could help you find the best treatment.
Westmead, New South WalesAges 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 - NCT05765175Recruiting
Radioablation versus repeat ablation for hard-to-treat VT
This trial compares a heart procedure using targeted radiation (called radioablation) to a repeat catheter ablation for people with high-risk, hard-to-control ventricular tachycardia (VT). It aims to find which approach is safer and works better after standard ablation and amiodarone have not stopped the abnormal rhythm.
Los Angeles, CaliforniaAges 18 years+ - 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+ - 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+ - NCT03444337Recruiting
High-resolution MRI before a special heart ablation for atrial fibrillation
This study uses high-resolution MRI scans to get a detailed picture of the heart before a special type of ablation for atrial fibrillation (an irregular heartbeat). The goal is to help doctors target the treatment more precisely.
Columbus, OhioAges 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 - NCT04664686Recruiting
Compare two heart-rhythm strategies after CRT for atrial fibrillation
This study looks at whether a “rate control” or “rhythm control” approach works better for people with CRT devices who still have atrial fibrillation. It aims to improve heart failure symptoms and help the heart pace more effectively.
LondonAges 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+ - NCT06557876Recruiting
Pulse field ablation for atrial fibrillation mechanics
This study tests if a new type of energy called pulse field ablation (a procedure that uses short bursts of electric pulses) works as well as standard ablation for restoring normal heart rhythm in patients with episodes of irregular heartbeat. It may help your heart pump more normally.
Paris, FranceAges 18 years+ - NCT04331249Recruiting
Monitoring heart device during and around your procedure
This trial looks at how to manage and check implanted heart devices (pacemakers/defibrillators) during and around a planned procedure. It may help teams improve safety and decision-making during surgery or catheter procedures.
Fürth, BavariaAges 18 years+ - NCT07130773Recruiting
Comparing two catheter types for atrial fibrillation ablation
This trial compares two types of special catheters (thin tubes) used during a procedure called ablation to treat atrial fibrillation (irregular heartbeat). It aims to see which catheter works better during the procedure, and may help improve future treatments for people with heart rhythm problems.
Lugano, Canton TicinoAges 18 years+ - 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 - NCT07047235Recruiting
Targeted ablation for persistent atrial fibrillation
This trial is testing a specific approach to catheter ablation for people with persistent atrial fibrillation. It aims to improve how abnormal heart tissue is targeted to help restore a normal rhythm.
LondonAges 18 years+ - NCT07585968Recruiting
New Catheter Treatment for Dangerous Heart Rhythms
This trial tests a new catheter-based procedure to treat life-threatening irregular heartbeats (ventricular tachycardia) that keep coming back despite medication. If you've had a heart attack and your implanted defibrillator hasn't fully controlled these arrhythmias, this procedure might help prevent future episodes.
Indianapolis, IndianaAges 18–85 - NCT07523750Recruiting
Pulsed field ablation for persistent atrial fibrillation
This study tests two types of pulsed field ablation catheters to treat persistent atrial fibrillation, a heart rhythm problem lasting more than 7 days but less than a year. The goal is to see if these catheters can safely and effectively restore a normal heart rhythm.

New catheter for ventricular tachycardia
This trial tests a new catheter system (Sphere-9 and Affera) to treat a fast, dangerous heartbeat called ventricular tachycardia (VT) in people with heart scarring. It aims to see if this system is safe and effective at stopping VT, especially if past treatments haven't worked.

Common questions
- Are there clinical trials for catheter ablation?
- Yes. Clin2 currently lists 118 recruiting 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 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 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.
