BaselAges 18 years+ - NCT03912324Recruiting
CT-guided heart imaging to guide treatment for atrial fibrillation
This trial studies whether using a special CT scan map of the heart muscle thickness can help doctors choose the best strategy during a cryoballoon procedure for paroxysmal atrial fibrillation. It may help improve effectiveness by tailoring treatment instead of using a standard approach.
SeoulAges 20–80 - NCT04281329Recruiting
CT and heart MRI add-on for atrial fibrillation ablation
This trial studies whether CT scans and heart MRI scans (done around the time of atrial fibrillation ablation) can help care planning and results. It may help your team better understand your heart before and after the procedure.
ParisAges 18 years+ - NCT04529785Recruiting
Tested added ethanol vein treatment during repeat atrial fibrillation ablation
This trial compares two ways to help stop atrial fibrillation during a repeat procedure: standard vein isolation only versus standard isolation plus an added medicine (ethanol) into the vein of Marshall. It aims to see whether the added step improves results when atrial fibrillation returns after a previous successful treatment.
Bruges, Please SelectAges 18 years+ - NCT04606693Recruiting
Screening for sleep apnea before heart rhythm ablation
This study looks at whether checking for sleep apnea (breathing pauses during sleep) and treating it helps people prepare for atrial fibrillation ablation. It may help by improving outcomes for patients with atrial fibrillation who keep having episodes despite medication.
Madrid, MadridAges 18 years+ - 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 - 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+ - NCT07523620Recruiting
Heart rhythm procedure with left atrial appendage closure
This trial tests a procedure that closes off a small pouch in the heart (left atrial appendage) while also treating irregular heartbeat (atrial fibrillation) with a catheter ablation procedure. The goal is to reduce your stroke risk and treat your symptoms without needing blood thinners long-term.
Brussels, B CAP RAges 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 - NCT05009797Recruiting
Study follow-up after catheter ablation for atrial fibrillation
This trial is looking at what happens after a heart procedure called catheter ablation for atrial fibrillation (an irregular heartbeat). It mainly collects follow-up outcomes to better understand recovery and results for patients.
LilleAges 18 years+ - NCT05014802Recruiting
MRI scans before heart surgery to predict post-surgery atrial fibrillation
This study uses an MRI scan before heart surgery to look for heart scarring that may predict who will develop atrial fibrillation afterward. Knowing the risk ahead of time could help doctors monitor you more closely and plan prevention.
Covington, LouisianaAges 40–120 - NCT05021601Recruiting
Ablation method comparison for rheumatic valve and ongoing AF
This study compares two heart procedures—targeting one or both upper heart chambers versus only the left upper chamber—to treat people with ongoing atrial fibrillation caused by rheumatic mitral valve disease. It aims to see which approach works better and is safer for restoring normal rhythm.
Beijing, Beijing MunicipalityAges 18 years+ - 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 - 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 - NCT05164107Recruiting
Test a new pulsed-field catheter procedure for atrial fibrillation
This trial tests a new pulsed-field device used during an atrial fibrillation (AF) catheter ablation, aiming to improve safety and effectiveness. It’s for people who have AF and are planning an AF ablation procedure.
PragueAges 18–75 - 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 - NCT05293080RecruitingPhase 3
Early heart rhythm treatment to help prevent stroke
This trial tests an early treatment approach for people who had a recent ischemic stroke (a stroke caused by a blocked blood vessel) and have an irregular heart rhythm called atrial fibrillation (AF). It aims to lower the chance of having another stroke by treating AF as early as possible after the stroke.
HamburgAges 18 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 - NCT05366361Recruiting
Study of persistent atrial fibrillation during heart procedures
This study looks at what happens in the heart in people with persistent atrial fibrillation when they undergo an ablation or Maze surgery. It may help doctors better understand the condition and improve future care for people needing these procedures.
Stanford, CaliforniaAges 22–80 - NCT05371405Recruiting
Using computer learning to improve care for atrial fibrillation patients
This study uses machine learning (computer pattern-finding) to better understand atrial fibrillation and guide care around the time of an ablation procedure. It may help refine how doctors treat certain AF patients based on their heart patterns.
Stanford, CaliforniaAges 22–80 - NCT05411614Recruiting
Testing two heart procedures for atrial fibrillation in heart failure
This study compares two different ablation procedures (treatments that target heart rhythm triggers) for people with atrial fibrillation and reduced heart pumping. It aims to see which approach works best and is safest for improving your heart rhythm when you also have heart failure.
ChertseyAges 18 years+ - NCT05427435Recruiting
Testing alcohol treatment of a heart vein during atrial fibrillation ablation
This study tests whether applying a small amount of alcohol to a specific heart vein (“vein of Marshall”) is safe and feasible during a standard atrial fibrillation (AF) ablation. It may help improve AF treatment, but the goal here is mainly to see if the approach can be done safely in the right patients.
PessacAges 18 years+ - NCT05434819Recruiting
Ablation study during heart surgery for atrial fibrillation
This trial looks at whether a special heart rhythm treatment called “ablation” works well when done during certain heart operations. It may help reduce atrial fibrillation (AF) symptoms or future abnormal rhythm episodes for people who are already having surgery.
Hamilton, OntarioAges 18 years+ - NCT05504356Recruiting
