Lifestyle Change to Improve AF Ablation Results
This trial tests whether a healthy lifestyle program (including exercise and weight loss) can help people with atrial fibrillation (AF) who are overweight or have related health risks. You will have a catheter ablation procedure, and the study will see if lifestyle changes improve your heart's rhythm long-term.
Calgary, AlbertaAges 18 years+ - NCT06249347Recruiting
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+ - NCT07181590Recruiting
Balloon-based ablation for atrial fibrillation: post-approval study
This trial tests a balloon catheter that uses pulsed field energy to treat atrial fibrillation (AF) in people who have tried medication without success. It aims to see how well it works in real-world use.
LinzAges 18 years+ - NCT04606693Recruiting
Screening for sleep apnea before heart rhythm ablation
This study looks at whether checking for sleep apnea (breathing pauses during sleep) and treating it helps people prepare for atrial fibrillation ablation. It may help by improving outcomes for patients with atrial fibrillation who keep having episodes despite medication.
Madrid, MadridAges 18 years+ - NCT04088071Recruiting
Ablation for heart rhythm problems using a specific technology
This study looks at how well catheter ablation works for treating certain heart rhythm disorders (like atrial fibrillation or ventricular arrhythmias) using a specific brand of catheters. The aim is to gather real-world data to better understand the procedure's outcomes.
Birmingham, AlabamaAges 18 years+ - NCT06510556Recruiting
Testing a new mapping and ablation system for AFib
This study tests a new device (FARAFLEX) that uses pulsed field energy to treat atrial fibrillation (AFib). You may qualify if you have persistent or paroxysmal AFib symptoms and have not had a prior ablation.
BrusselsAges 18 years+ - NCT06557616Recruiting
CoolCryo system for treating atrial fibrillation during mitral valve surgery
This trial tests a new tool called CoolCryo that freezes heart tissue to treat atrial fibrillation while you have mitral valve surgery. If you are already having this surgery and also have AF, this device could correct both problems at once.
BydgoszczAges 18 years+ - NCT07444320Recruiting
Testing new energy pulses for atrial fibrillation treatment
This trial tests a new way to deliver energy (FARAPULSE PFA system) to treat atrial fibrillation (AF), a type of irregular heartbeat. It aims to see if these new waveforms can safely and effectively stop AF symptoms and improve quality of life.
