New ablation approach for persistent atrial fibrillation with stroke risk
This trial tests a new type of catheter ablation (using heat to create scar lines in the heart) for people with persistent atrial fibrillation who have a higher risk of stroke or bleeding. It aims to see if this approach can help prevent strokes and reduce the need for long-term blood thinners.
Wenzhou, ZhejiangAges 18 years+ - NCT06145906Recruiting
Optimizing catheter ablation for atrial fibrillation
This trial is studying a way to improve the entire process of catheter ablation for atrial fibrillation. It may help people who are having this procedure for the first time and have a normal-sized left atrium and good heart function.
Zhengzhou, HenanAges 18–80 - 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 - NCT04432220RecruitingPhase 4
Taking blood thinners one year after atrial fibrillation ablation
This study looks at whether people who have stayed in normal rhythm one year after atrial fibrillation ablation should continue blood thinning treatment. It may help guide safer, more personalized choices about long-term blood thinners after a successful procedure.
SeoulAges 19–80 - NCT06165510Recruiting
Convergent ablation and left atrial appendage isolation for persistent AF
This trial tests a two-step procedure for persistent atrial fibrillation that combines a heart ablation with isolation of a small heart pouch. It aims to see if this approach is more effective than standard care.
LondonAges 18–80 - NCT07272902Recruiting
Atrial fibrillation treatment: Ablation vs. medication
This trial compares two ways to treat atrial fibrillation in people with heart failure where the heart's pumping strength is still normal. You'll either get a procedure called ablation to restore normal rhythm or medication to control your heart rate. The goal is to see which approach works better for people like you.
Halifax, Nova ScotiaAges 18 years+ - 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+ - NCT05511246RecruitingPhase 2
Alcohol injection for fast heart rhythm
This trial tests injecting ethanol (alcohol) into a vein near the heart to treat a dangerous fast heart rhythm called ventricular tachycardia. It may be an option for people who have an implanted defibrillator and have not found relief with other treatments.
Houston, TexasAges 18–85 - NCT04499326Recruiting
Improve quality-of-life reporting after defibrillator heart ablation
This study looks at how to better track patients’ quality of life (how you feel and function) after catheter ablation for a dangerous heart rhythm, using questionnaires you complete. It may help the care team understand how to measure patient outcomes more accurately after treatment.
LondonAges 18 years+ - NCT05116384Recruiting
Renal nerve ablation plus AF ablation for persistent AF
This study tests whether treating kidney-related nerves along with the usual AF (irregular heartbeat) catheter procedure works better than the usual procedure alone. It may help some people with persistent AF, but you must meet specific heart and kidney safety requirements.
Short Hills, New JerseyAges 18 years+ - NCT05557526Recruiting
Improving quality of life after atrial fibrillation ablation
This study aims to improve how patients feel in daily life after a procedure to treat atrial fibrillation (an irregular heartbeat). It focuses on whether better patient expectations and support can lead to a better quality of life after the procedure.
Düsseldorf, North Rhine-WestfaliaAges 18 years+ - 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+ - NCT05794464Recruiting
Safe tracking registry for people with Afib
This registry is collecting health information from people with atrial fibrillation (Afib) who are being considered for a procedure to restore normal rhythm. It aims to better understand safety and outcomes so future care can be improved.
Ostrava, Moravian-Silesian RegionAges 18 years+ - NCT06216769Recruiting
Pill-in-the-pocket blood thinners after AF ablation
This study tests a 'pill-in-the-pocket' approach for blood thinners after a catheter ablation for atrial fibrillation. Instead of taking a daily blood thinner, you may only take it when needed, which could reduce the risk of bleeding while still preventing strokes.
SeoulAges 19–89 - NCT06360939Recruiting
Radiation or ablation for ventricular tachycardia in heart disease
This trial compares two treatments—radiation therapy or catheter ablation—for people with structural heart disease who have a type of fast heart rhythm called ventricular tachycardia. It aims to see which approach works better to prevent repeat episodes.
WestmeadAges 18 years+ - NCT06528262RecruitingPhase 4
Study of enavogliflozin to prevent atrial fibrillation return after heart ablation
This trial tests if enavogliflozin, a diabetes drug, can help prevent atrial fibrillation (an irregular heartbeat) from coming back after a catheter ablation procedure in people with heart failure. If you've recently had or are planning this procedure, this study may offer a new way to keep your heart rhythm steady.
SeoulAges 19–84 - NCT06542263Recruiting
CPAP for preventing AF recurrence after ablation in people with AF and sleep apnea
This study tests whether using a CPAP machine at night can help prevent atrial fibrillation from coming back after a heart procedure called catheter ablation. It is for people who have both AF and moderate to severe obstructive sleep apnea.
Suzhou, JinagsuAges 18 years+ - NCT06584266Recruiting
Cardiac imaging registry for atrial fibrillation
This study collects data from heart imaging tests (TEE) in people with atrial fibrillation or atrial flutter. It aims to better understand how these imaging results relate to treatment decisions and outcomes.
BrnoAges 18 years+ - NCT06602635Recruiting
New scoring system for outflow tract arrhythmias with wide QRS
This study is testing a new scoring system (called a Hybrid Score) to better predict the origin of ventricular arrhythmias coming from the outflow tract of the heart. The goal is to improve treatment planning for people with a wide QRS complex on their ECG.
Brussels, BelgiumAges 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 - NCT07036965Recruiting
Comparing two types of ablation catheters for atrial fibrillation
This trial tests two different catheters that use pulsed field energy to treat atrial fibrillation (a heart rhythm problem). It aims to find which one works better for people who need blood thinners but have a high risk of bleeding.
HangzhouAges 118 years+ - NCT07271238Recruiting
Study of a new imaging system for heart ablation
This study tests a new imaging system (VERAFEYE) that helps doctors guide catheter ablation, a procedure to fix irregular heartbeats like atrial fibrillation. It aims to see if the system makes the procedure safer or more effective.
SplitAges 18 years+ - NCT02138695Recruiting
Study of outcomes after atrial fibrillation catheter ablation
This study follows people after a procedure called catheter ablation to treat atrial fibrillation (an irregular heart rhythm). It aims to learn which factors help predict outcomes, so future care can be better tailored.
SeoulAges 19 years+ - NCT07447297Recruiting
Early Rhythm Control for Device-Detected Fast Heart Episodes
This trial tests whether starting treatment early to control your heart's rhythm can help people with a heart device who have short bursts of a fast heartbeat (called atrial high rate episodes) but haven't yet been diagnosed with atrial fibrillation on a standard EKG or Holter monitor.
