Comparing two procedures for persistent atrial fibrillation with enlarged left atrium
This study compares two procedures to treat persistent atrial fibrillation in people whose upper left heart chamber is enlarged: catheter ablation (a minimally invasive procedure using a tube through a vein) versus thoracoscopic ablation (a surgical approach using small chest incisions). The goal is to see which method better restores a normal heart rhythm.
Seoul, SeoulAges 19 years+ - NCT04678258Recruiting
Study without x-ray guidance for treating atrial flutter
This trial tests a way to do a heart procedure for “atrial flutter” with less or no x-ray use. It may help reduce radiation exposure while still aiming to cure the abnormal rhythm.
Fürth, BavariaAges 18 years+ - 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.

Changsha, HunanAges 18–80 - NCT06691074Recruiting
Long-lasting CTI block with pulsed field ablation
This trial tests a new type of energy called pulsed field (gentle electrical pulses) to create a permanent block in the CTI area—a spot in the heart that can cause a fast, fluttering rhythm. It may be an option for people with both atrial fibrillation and typical atrial flutter.
Prague, PragueAges 18 years+ - NCT06883864Recruiting
Ablation for leaky valve with constant atrial fibrillation
This study tests whether a catheter ablation procedure (a way to fix abnormal heart rhythms) can help people who have both constant atrial fibrillation and severe mitral regurgitation (a leaky heart valve). It is for people whose heart valve leak is caused by the rhythm problem, not by valve damage.
Hefei, AnhuiAges 18–80 - NCT07064616Recruiting
Pulsed field vs. cryoballoon ablation for persistent atrial fibrillation
This trial compares two techniques—pulsed field ablation and cryoballoon ablation—to treat persistent atrial fibrillation (a type of irregular heartbeat that lasts less than a year). The goal is to see which method works better and is safer for patients.
Sagamihara, KanagawaAges 18–85 - NCT07441382Recruiting
Comparing treatments for frail older adults with atrial fibrillation
This study tests whether combining a heart procedure (catheter ablation) with a device to close the left atrial appendage (LAAO) is safer or better than blood thinners alone for frail patients 75 years or older with atrial fibrillation and high stroke risk. It aims to find a treatment that reduces stroke while lowering bleeding risks.
Guangzhou, GuangdongAges 75 years+ - NCT03729232Recruiting
Japanese registry for people who had catheter ablation
This is a national registry that collects health information from people in Japan who received catheter ablation. It may help doctors and researchers understand outcomes and improve future care.
Suita, OsakaAges Any age - NCT06556485Recruiting
Early ablation for heart failure patients with heart pumps or on transplant list
This trial tests whether doing a catheter ablation early (before dangerous heart rhythms start) can help people with severe heart failure who need a heart transplant or already have an ICD. The goal is to see if this can improve outcomes.
Bad OeynhausenAges 18–99 - 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.
Los Angeles, CaliforniaAges 18 years+ - NCT02558699Recruiting
Virtual mapping guided catheter ablation for atrial fibrillation
This trial tests whether a “virtual” computer map created from your heart scans can help doctors do catheter ablation to treat atrial fibrillation (AF). It aims to improve the procedure for people whose AF symptoms were not controlled well with anti-arrhythmia medicines.
SeoulAges 19–80 - NCT07601763Recruiting
Pulsed Field Ablation for Atrial Fibrillation Treatment
This trial tests a newer ablation technique called pulsed field ablation to treat atrial fibrillation, a heart rhythm disorder. The goal is to see if this method works well and is safe for patients who need treatment.
Beijing, Beijing MunicipalityAges 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 - NCT05047198RecruitingPhase 3
Catheter procedures to stop dangerous heart rhythm episodes
This study compares two catheter-based procedures to treat ventricular tachycardia (VT), a fast, dangerous heart rhythm. It looks to see which approach works better at reducing repeat VT events in people with weakened heart pumping.
Ottawa, OntarioAges 55 years+ - NCT07141745Recruiting
Comparing energy types for repeat atrial fibrillation treatment
This trial compares two different energy methods (electroporation vs radiofrequency ablation) guided by 3D imaging for people who have had a prior ablation for atrial fibrillation but still have recurrences. It aims to find which method is safer and more effective for repeat procedures.
