Recruiting studies
- NCT06989580Recruiting
Heart failure monitoring with a wireless implant
This trial is testing a special monitor (BIOMONITOR) that tracks your heart function and sends data wirelessly to your doctor. It aims to help manage heart failure by catching early signs of trouble so you can get treatment sooner.

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.

Clot-busting treatment after stroke while on Factor Xa inhibitor
This trial tests a clot-busting drug (thrombolysis) for people who had a stroke while on a Factor Xa inhibitor blood thinner. It aims to see if the drug can still safely break up the clot and reduce disability.
Aalborg, AalborgAges 18 years+ - NCT06861673Recruiting
Combined PVI and LAAC study
This study is testing if a procedure that combines two treatments—pulmonary vein isolation for atrial fibrillation and left atrial appendage closure to lower stroke risk—can be done safely together. It's for people who need both treatments.
Hamburg, Free and Hanseatic City of HamburgAges Any age - NCT06828939Recruiting

Chest tube duration to prevent afib after heart surgery
This trial tests if leaving a chest tube in a little longer after heart surgery can lower the chance of developing atrial fibrillation (an irregular heart rhythm). It's for people having certain planned heart surgeries who have not had this rhythm problem before.
LundAges 18 years+ - NCT06789588Enrolling by invitationPhase 3
Better warfarin therapy for atrial fibrillation

Recife, PernambucoAges 18 years+ - NCT05432024Recruiting
Heart MRI checks how well ablation lesions form
This study uses a special heart MRI to look at how ablation creates scar tissue in people with atrial fibrillation. It may help doctors improve how ablation is done and understand which technique works best.
NieuwegeinAges 18 years+ - NCT06747091Recruiting
Ablation study for people with persistent atrial fibrillation
This trial tests a catheter ablation procedure for people with persistent atrial fibrillation (a type of irregular heartbeat that lasts more than 7 days but less than a year). It aims to see if the procedure is safe and effective for restoring a normal heart rhythm.
Manhasset, New YorkAges 18–80 - NCT06731673Recruiting
HSP47 protein study in blood clots
This study looks at a protein called HSP47 in people with blood clots, heart attacks, or strokes caused by atrial fibrillation, compared to healthy volunteers. It aims to learn more about how blood clots form and may lead to better treatments.
Aarhus, Central RegionAges 18 years+ - NCT06650995Recruiting
Ablation and Exercise for Heart Failure with Normal Pumping
This study tests whether a combination of catheter ablation (a procedure to correct irregular heartbeats) and a structured exercise program can improve symptoms and quality of life in people with diastolic heart failure and a recent onset of persistent atrial fibrillation.
MunichAges 18–99 - NCT06589700Recruiting
Atrial Fibrillation and Stroke Risk Study
This study looks at the link between the type of atrial fibrillation (an irregular heartbeat that comes and goes) and the risk of having another stroke. It involves people who have had a recent ischemic stroke and have a certain type of AF.
London, OntarioAges 18 years+ - NCT06583395Enrolling by invitation
Meditation retreat study with fitness tracker
This trial studies people attending a 7-day meditation retreat to see how meditation affects well-being. You will wear a fitness tracker and answer surveys.
Palm Desert, CaliforniaAges 21 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+ - NCT06575881Recruiting
Genetic heart muscle disease and heart rhythm study
This study looks at the risk of a fast heart rhythm (ventricular tachycardia) in people with genetic heart muscle diseases. It tests whether having a specific genetic change affects the success of a heart ablation procedure.
Nashville, TennesseeAges 18 years+ - NCT06556667Recruiting
Comparing two cardioversion methods for persistent AFib
This trial compares two ways of doing cardioversion (a procedure to restore normal heart rhythm) for people with persistent atrial fibrillation. It aims to see if one approach leads to a better recovery and fewer complications.
Ottawa, OntarioAges 18 years+ - NCT06529978Recruiting
CoreMap heart mapping for atrial fibrillation ablation
This study tests a new mapping system that helps doctors see the electrical signals in your heart more clearly during a standard ablation for persistent atrial fibrillation. It may improve the accuracy of the treatment.
Naples, FloridaAges 18–80 - NCT06511505Recruiting
Testing AI to find hidden heart conditions from ECGs
This study uses an AI tool to look at your ECG (a simple heart test) to help find early signs of atrial fibrillation (an irregular heartbeat) or structural heart disease (changes in heart structure). It aims to see if the AI can help doctors catch these conditions sooner, even in people who don't yet have symptoms.
Chicago, IllinoisAges 40 years+ - NCT06465459Recruiting
Testing the LAMBRE device for left atrial appendage closure
This study is testing a device called LAMBRE that is used to close a small pocket in the heart (the left atrial appendage). The goal is to see how well it works in everyday medical practice for people who need this closure procedure.
PessacAges 18 years+ - NCT06393920Recruiting
PulseSelect PFA heart ablation registry study
This registry study collects information from people with atrial fibrillation (an irregular heartbeat) who are having a procedure using the PulseSelect PFA system. It helps doctors understand how well this treatment works in real-world settings.
HasseltAges 18 years+ - NCT05643235Recruiting
Loop monitor to watch heart rhythms when starting a BTK inhibitor
This study checks how often abnormal heart rhythms happen when you start a BTK inhibitor (used for certain blood cancers). It uses a small implanted heart monitor to record your rhythm continuously before and after starting the medication, so doctors can detect and manage problems early.
New Hyde Park, New YorkAges 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.

Common questions
- Are there clinical trials for atrial fibrillation?
- Yes. Clin2 currently lists 543 recruiting atrial fibrillation 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 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 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.
