Test of a new catheter procedure for irregular heart rhythm
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have atrial fibrillation that is either paroxysmal or persistent, and it has been documented more than once in the last 12 months
- At least one anti-arrhythmia heart rhythm medicine tried before either failed or you couldn’t tolerate it
- Your doctor says you are a suitable candidate for catheter ablation
- You are age 18 to under 75, and you can give informed consent
- You can follow all required checkups and testing before and after the procedure

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.
This trial tests a new catheter system to treat atrial fibrillation (AF) by creating small scars in the heart to block faulty signals. It may help people with symptoms that continue despite medication and who are scheduled for a standard ablation procedure.
This study tests a new type of catheter ablation (a procedure that uses energy to treat irregular heartbeats) for atrial fibrillation—a common heart rhythm problem. You may qualify if you have recurring irregular heartbeats that haven't responded well to heart medications and are planning to have this procedure.
This study tests a new catheter system, called Varipulse, to see if it's safe and effective for treating atrial fibrillation (AF), a heart rhythm problem. People with short-lasting AF who haven't been helped by medication may be able to join.
This trial tests a new pulsed-field device used during an atrial fibrillation (AF) catheter ablation, aiming to improve safety and effectiveness. It’s for people who have AF and are planning an AF ablation procedure.
This trial tests a new method called pulsed field ablation (PFA) to treat irregular heartbeats (atrial fibrillation) by isolating the veins that carry blood to your heart. It aims to see how well this procedure works and if it's safe for you.
