Device test for treating irregular heartbeat with AF ablation
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’ve been diagnosed with paroxysmal or persistent atrial fibrillation, with at least two documented episodes in the past year
- You’ve tried at least one atrial fibrillation medicine (Class I–IV) but it didn’t work or you couldn’t tolerate it
- Your doctor believes you’re a suitable candidate for a catheter ablation procedure
- You are 18 to under 75 years old and can sign consent
- You must be able to follow all required testing before and after the procedure
- You likely do not have certain heart rhythm causes or other heart conditions that make ablation unsafe or unsuitable

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 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.
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 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 advanced technology to improve how atrial fibrillation (AFib) is treated with a heart ablation procedure. It may help patients who are already advised to have AFib ablation by seeing how well the approach works in real clinical practice.
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.
