Catheter ablation for slow heart rate study
This study tests a catheter procedure to treat a slow heart rate (bradycardia) that causes symptoms like dizziness or fainting. It may be an option for people who haven't had a pacemaker and whose heart can still speed up with medication.
Beijing, ChinaAges 18–65 - NCT07535268Recruiting
Heart rhythm ablation outcomes in minority patients
This registry tracks outcomes for racial and ethnic minority patients undergoing a specific type of heart rhythm treatment (ablation) for atrial fibrillation. The goal is to understand how well this treatment works across different populations.
New York, New YorkAges 18 years+ - NCT07607093Recruiting
Early rhythm control for atrial fibrillation with tricuspid valve leakage
This trial tests whether treating atrial fibrillation (an irregular heartbeat) early helps patients who also have tricuspid regurgitation (leakage in a heart valve). Researchers want to see if controlling the heart rhythm early can improve outcomes for people with both conditions.
Seoul, SeoulAges Any age - NCT07671898Recruiting
Freezing vs. Radiofrequency for Slow Heart Rate
This trial compares two procedures to treat very slow heart rates without needing a pacemaker. One uses freezing (cryoablation) and the other uses radiofrequency energy to target nerves that control heart rate.
Tomsk, Tomsk OblastAges 18–60 - NCT06802965Enrolling by invitation
Shanghai atrial fibrillation patient registry study
This study tracks people in Shanghai who have been diagnosed with atrial fibrillation (AF, a heart rhythm condition). By joining a registry, researchers can learn more about how AF is managed over time in the local population.
ShanghaiAges Any age - NCT04520347Enrolling by invitation
Registry for heart rhythm ablation in VT or PVC
This study is a “registry,” meaning it collects information about people undergoing a procedure to treat abnormal heart rhythms like ventricular tachycardia (VT) or premature ventricular contractions (PVCs). It may help researchers better understand which patients benefit from the procedure and how it is done over time.
Phoenix, ArizonaAges Any age - 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 - NCT06455098Recruiting
Pulsed field ablation for paroxysmal atrial fibrillation
This study tests a new procedure called pulsed field ablation using a special catheter to treat paroxysmal atrial fibrillation (AF), a type of heart rhythm problem that comes and goes. It may be an option for people whose AF hasn't been controlled well with medication.
Phoenix, ArizonaAges 18–80 - NCT06543173Recruiting
Preventive heart ablation with defibrillator in high-risk patients
This study tests if doing a special heart procedure (catheter ablation) at the same time as implanting a defibrillator (ICD) can prevent dangerous heart rhythms better than the ICD alone. It is for people with a very weak heart pump due to blocked arteries who are getting a first-time ICD.
Copenhagen, Region HAges 18 years+ - NCT05227053Recruiting
Cryoablation study for paroxysmal atrial fibrillation after approval
This study looks at outcomes after a specific heart procedure called pulmonary vein isolation done with a cryoablation catheter. It is for adults with symptomatic “paroxysmal” atrial fibrillation who are planning this exact procedure.
Anchorage, AlaskaAges 18 years+ - NCT07541092Recruiting
Optrell Catheter for Heart Rhythm Problems from Papillary Muscles
This study compares how well a special heart mapping catheter (Optrell) works in treating irregular heartbeats that start in specific heart muscle areas called papillary muscles. If you're having frequent or bothersome extra heartbeats, this trial may help you get a procedure your doctor already recommends.
New Hyde Park, New YorkAges 18–75 - NCT06333327Recruiting
Atrial fibrillation ablation with a balloon catheter registry
This study is collecting data on people having a procedure called catheter ablation for atrial fibrillation using a special radiofrequency balloon. The goal is to see how well it works and to help improve future treatments.
BrusselsAges 18–85 - 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+ - NCT05948904Recruiting
Cryogenic catheters tested in donated lung tissue
This study tests a technique using a special cold (cryogenic) catheter to collect samples (biopsy) and destroy abnormal lung tissue (ablation) in lungs outside the body. It’s aimed at improving how pulmonary (lung) lesions could be diagnosed and treated in the future.
Montreal, QuebecAges 18 years+ - NCT05996159Recruiting
Using very high power for short duration to treat atrial fibrillation
This study tests a new way to perform a common procedure (pulmonary vein isolation) for people with paroxysmal atrial fibrillation. Instead of using the standard amount of energy for a longer time, this method uses a very high amount of energy for a very short time. This might make the procedure faster and just as safe.
SeoulAges 19 years+ - NCT07301190Recruiting
Study of PFLotus for persistent atrial fibrillation
This study tests a new device called PFLotus for people with persistent atrial fibrillation (AF), a type of irregular heartbeat. The goal is to see if it can help restore a normal heart rhythm in people who haven't gotten better with medicine.
ChengduAges 18–75 - NCT06647251Recruiting
Comparing different radiofrequency modes for atrial fibrillation ablation
This trial tests three different ways of delivering radiofrequency energy using a specific catheter (QDOT) during a first-time procedure to treat atrial fibrillation (AF), a type of irregular heartbeat. It aims to find which method works best for patients with recent or short-lasting AF episodes.
Paris, ParisAges 18 years+ - NCT06940752Enrolling by invitation
