- NCT07508618RecruitingPhase 4
Qidong Yixin Granule for preventing atrial fibrillation after ablation
This trial tests whether a traditional Chinese medicine granule, Qidong Yixin, can help prevent atrial fibrillation from coming back after a heart ablation procedure. It is for people with persistent atrial fibrillation who have not had good results from other heart rhythm medications.
HangzhouAges 18–80 - NCT07424326Recruiting
Extended ablation vs. standard treatment for persistent atrial fibrillation
This trial compares two catheter ablation techniques for people with persistent atrial fibrillation (a type of irregular heartbeat that doesn't go away on its own). It will test whether a more extensive ablation (burning more heart tissue) works better than the standard procedure of isolating the pulmonary veins (the veins that bring blood from the lungs to the heart). If you have this condition and have had at least one episode in the past year, this study might help you find a more effective treatment.
OlomoucAges 18–80 - NCT05908955Recruiting
Atrial fibrillation ablation with extra vein targeting
This trial studies a modified ablation procedure that targets the superior vena cava in addition to the pulmonary veins to help stop episodes of paroxysmal (coming and going) atrial fibrillation. It may help people whose symptoms continue despite antiarrhythmic medicines.
Beijing, Beijing MunicipalityAges 40–75 - NCT06825104Recruiting
Long-term comparison of two ablation methods for persistent AF
This long-term study follows people who already completed a 12-month study comparing two types of heart ablation for persistent atrial fibrillation. It looks at how well the treatments worked over time.
BronAges 18 years+ - NCT05903170Recruiting
Shock energy study for heart rhythm conversion in atrial fibrillation
This trial tests whether using a specific “shock energy” during electrical cardioversion works safely and effectively for people with persistent atrial fibrillation. You might be eligible if your cardioversion is planned (not an emergency) and your doctors determine you can safely take blood thinners.
Wellington, Wellington RegionAges 18 years+ - NCT05565781Recruiting
Watch for hidden atrial fibrillation after unexplained stroke
This study uses a smartwatch and a longer heart-monitoring test (a Holter) to find an irregular heart rhythm called atrial fibrillation after a stroke whose cause is unclear. If they detect it, it may help guide better prevention and treatment to reduce future stroke risk.
Barcelona, CataloniaAges 55 years+ - NCT07095959Recruiting
Ethanol vein infusion plus pulsed field ablation for paroxysmal AF
This study compares two treatments for paroxysmal atrial fibrillation (AF that comes and goes): using pulsed electric field ablation alone versus combining it with ethanol infusion into a specific vein. The goal is to see which approach works better for first-time ablation patients.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07077811Enrolling by invitation
Pulsed field ablation for heart failure with preserved pumping strength
This trial tests a new procedure called pulsed field ablation for people who have both persistent atrial fibrillation and a type of heart failure (HFpEF). It aims to see if this ablation safely helps control the heart rhythm.
Nantong, JiangsuAges 18–80 - NCT06960252Recruiting
Cycle length mapping for long-term atrial fibrillation
This study tests a new mapping technique to find chaotic electrical signals in the heart during persistent atrial fibrillation. It may help doctors better target treatment for people whose atrial fibrillation does not stop with medication.
Taipei, Outside USAges 20 years+ - NCT06833138Recruiting
Pacing vs medication for heart rate control in AF with heart failure
This trial tests whether a procedure that regulates your heart rhythm (pacing) works better than medication for people who have permanent atrial fibrillation, heart failure with a normal pumping strength, and were hospitalized for heart failure in the past year.
BesançonAges 18 years+ - 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 - NCT05794386Recruiting
Ablation plan guided by left-heart scar map for persistent atrial fibrillation
This study tests whether using a 3D heart “scar map” helps doctors choose a better catheter ablation strategy for people with persistent atrial fibrillation (AF). It may help reduce ongoing AF by targeting the scar area in the left atrium.
Seoul, Jongno-guAges 19 years+ - 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 - 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+ - NCT03397602Recruiting
Exercise program for long-term atrial fibrillation
This trial studies how an exercise training program affects people with persistent or permanent atrial fibrillation (an irregular heart rhythm). It may help improve how you feel and how well your heart and body handle activity.
London, OntarioAges 40 years+ - NCT05292209RecruitingPhase 2
RiLuzole pill to reduce atrial fibrillation on heart monitoring
This Phase 2 study tests whether riLuzole can reduce episodes of atrial fibrillation (an irregular heart rhythm) around the time of planned cardioversion. Doctors will monitor your heart using a Holter monitor to count and compare rhythm episodes.
Salt Lake City, UtahAges 18 years+ - NCT06383975Recruiting
Two new treatments for AF that returned after first procedure
This trial tests two new treatments for persistent atrial fibrillation that came back after an initial procedure. One uses a targeted chemical injection, the other uses a special energy field to re-isolate the veins involved.
BrugesAges 18 years+ - 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 - 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 - NCT06929897Enrolling by invitation
Comparing Two Ablation Methods for Persistent Atrial Fibrillation
This study compares two types of ablation (a procedure that uses energy to fix irregular heartbeats) for people with persistent atrial fibrillation. It tests whether adding extra treatment to the back of the heart's left upper chamber helps improve outcomes compared to standard treatment alone.
SeoulAges 20–80 - NCT06801392Recruiting
Pulsed-field ablation for non-paroxysmal atrial fibrillation
This trial tests a new way to treat non-paroxysmal atrial fibrillation (AF) using a focused type of ablation (pulsed-field energy) on specific areas of the heart. It aims to see if targeting the left atrial wall and mitral isthmus can improve outcomes for people who have not had this procedure before.
PragueAges 18 years+ - NCT06096246Recruiting
Comparing treatments for persistent atrial fibrillation
This study compares two treatments for persistent atrial fibrillation (AF) that lasts more than 7 days but less than 2 years: electrical cardioversion (a shock to reset your heart rhythm) versus catheter ablation (using radio waves to fix the heart's electrical pathways). It aims to find which option works better for patients like you.
LondonAges 18–85 - NCT05264831Recruiting
Ablation treatment after failed electric heart shock
This trial tests whether blocking faulty heart signals from the pulmonary veins (with or without additional “substrate” modification) works better when electric cardioversion doesn’t stop persistent atrial fibrillation. It may help people who remain in atrial fibrillation after cardioversion by reducing symptoms and abnormal rhythm over time.
