Pulsed-field ablation for recurrent atypical atrial flutter
This study tests a new type of energy called pulsed-field ablation (PFA) to treat a specific kind of irregular heartbeat called atypical atrial flutter that keeps coming back after a prior ablation. It aims to see if this approach can safely stop the abnormal rhythm.
TaipeiAges 18–80 - NCT06542263Recruiting
CPAP for preventing AF recurrence after ablation in people with AF and sleep apnea
This study tests whether using a CPAP machine at night can help prevent atrial fibrillation from coming back after a heart procedure called catheter ablation. It is for people who have both AF and moderate to severe obstructive sleep apnea.
Suzhou, JinagsuAges 18 years+ - NCT05963698Recruiting
Closing off a heart pouch to prevent stroke
This study tests a procedure that seals off the left atrial appendage (a small heart pouch) to help prevent stroke in people with atrial fibrillation. You may be considered if your stroke risk is high and you are already on blood-thinner medicine.
Birmingham, AlabamaAges 18 years+ - NCT07390175Recruiting
New heart-ablation method for long-lasting arrhythmias
This study tests a new way to destroy the tissue causing dangerous heart rhythms using a detailed model of how the heart's electrical signals spread. It may be an option for people with long-lasting atrial fibrillation or hard-to-control ventricular arrhythmias who are already scheduled for a standard ablation procedure.
Madrid, MadridAges 18 years+ - NCT06578104Recruiting
Pulsed AF Study: PulseSelect Catheter for Afib
This study tests a new way to treat atrial fibrillation (Afib) using a special catheter system called PulseSelect that delivers short bursts of energy to create scar tissue in the heart. It is for people whose Afib comes and goes or stays for a while but not more than a year, and who have not had a prior ablation procedure or have a pacemaker or defibrillator.
Tampa, FloridaAges 18 years+ - NCT07390214Recruiting
Comparing two catheters for repeat atrial fibrillation ablation
This study compares two types of catheters (AFFERA vs. standard contact-force guided) for a repeat ablation procedure in people whose atrial fibrillation or related symptoms returned after a first ablation. It aims to find which catheter works best for a second treatment.
Frankfurt am Main, HesseAges 18–85 - NCT07096219Enrolling by invitation
Catheter Ablation for Leaky Mitral Valve in Persistent Atrial Fibrillation
This trial tests if catheter ablation—a procedure to fix heart rhythm—can help people with a leaky mitral valve that is caused by atrial fibrillation (functional mitral regurgitation). If you have persistent atrial fibrillation and moderate leaky valve, you may benefit from this treatment.
Guangzhou, GuangdongAges 18–75 - NCT06828939Recruiting
Balloon treatment for atrial fibrillation
This trial tests a new balloon device that uses gentle energy pulses to treat atrial fibrillation (AF), a type of irregular heartbeat. It may help people whose AF has not improved with medication.
Prague, Czech RepublicAges 18–75 - NCT07308847Recruiting
Study of a new catheter system for treating atrial fibrillation
This trial tests a new catheter and mapping system designed to treat paroxysmal atrial fibrillation (AF), which is a type of irregular heartbeat that comes and goes. If you have this condition, the study aims to see how well the new system works with a minimally invasive procedure.
Jonesboro, ArkansasAges 18–80 - NCT07429214Recruiting
Study of a new catheter for atrial fibrillation ablation
This trial tests a new catheter system to treat atrial fibrillation (AF) by creating small scars in the heart to block faulty signals. It may help people with symptoms that continue despite medication and who are scheduled for a standard ablation procedure.
AalstAges 18–75 - NCT05300997Recruiting
Test blood and antibody markers for suspected acute stroke
This study looks at blood tests to find signs of immune activity after a suspected stroke. It may help doctors diagnose stroke faster and better understand what is happening in the body soon after symptoms start.
Hong KongAges 18–100 - NCT05826665Recruiting
Study of heart rhythm mapping during AF ablation
This is an observational study that looks at how a special heart mapping system may affect the procedure and outcomes for people having ablation for persistent atrial fibrillation (AF). It may help doctors better understand what works best and how procedures turn out.
Jonesboro, ArkansasAges 18–80 - NCT06164808Recruiting
Comparing a wearable heart monitor to a standard Holter monitor
This study compares a new wearable heart monitor (HeartWatch) that you wear on your left bicep to the standard Holter monitor. It aims to see if the HeartWatch is as good at recording your heart's rhythm over 24-48 hours, so you might have a more comfortable option for heart monitoring.
Calgary, AlbertaAges 22 years+ - NCT06657404Recruiting
Modified 'Pills-in-the-Pocket' strategy for AF after ablation
This study tests a modified 'pills-in-the-pocket' approach—taking antiarrhythmic drugs only when symptoms occur—for people with non-valvular atrial fibrillation (AF) who still have arrhythmias lasting over 24 hours after their first catheter ablation. It aims to see if this strategy can safely control symptoms without needing daily medication.
Guangzhou, GuangdongAges 18 years+ - NCT07428564Recruiting
VARIPULSE catheter and TRUPULSE generator for persistent atrial fibrillation
This study tests a new catheter and generator system to treat persistent atrial fibrillation (an irregular heartbeat that lasts more than a week). It may help people whose symptoms haven't been controlled by medication and who need a procedure called ablation to fix the heart's electrical signals.
AalstAges 18–75 - NCT06935591Recruiting
AI-guided ablation for hard-to-treat atrial fibrillation
This trial uses an artificial intelligence system (vMap) to find and target abnormal electrical signals outside the pulmonary veins that may be driving atrial fibrillation (AF). The goal is to improve ablation results for people with persistent or recurrent AF.
Jonesboro, ArkansasAges 22 years+ - NCT07224178Recruiting
Heart strain and stroke of unknown cause
This study looks at how well the left side of the heart pumps (called strain) in people who had a stroke without a known cause. It aims to see if this heart measurement can help predict future strokes or heart rhythm problems like atrial fibrillation.

Common questions
- Are there clinical trials for atrial fibrillation recurrent?
- Yes. Clin2 currently lists 65 recruiting atrial fibrillation recurrent 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 atrial fibrillation recurrent 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 recurrent 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.
