SeoulAges 19 years+ - NCT07799519RecruitingPhase 2
Finerenone after heart procedure to lower atrial fibrillation return
This trial tests whether taking finerenone after a heart procedure to fix irregular heartbeat can help prevent atrial fibrillation from coming back. It's for people having their first such procedure and aims to improve long-term heart rhythm health.
TainanAges 18–80 - NCT07759427Recruiting
Using a new mapping method to guide treatment for fast heartbeats after a heart attack
This study tests a new way to find the exact spot in the heart that causes rapid heartbeats, so doctors can treat it more precisely with a procedure called catheter ablation.
BrightonAges 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+ - 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 - 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 - 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+ - NCT07468383Recruiting
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 - 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.
Seoul, SeoulAges 19 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+ - 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+ - 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.
