Testing a new catheter ablation method for irregular heartbeat
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Age 18 or older
- Diagnosed with paroxysmal atrial fibrillation (irregular heartbeats that stop on their own within 7 days) or persistent atrial fibrillation (lasting more than 7 days but less than 1 year), with at least one documented episode
- Your irregular heartbeats have caused noticeable symptoms (like shortness of breath, chest discomfort, or fatigue) in the past 6 months
- Heart rhythm medications (antiarrhythmic drugs) have either not worked well enough or caused side effects that you couldn't tolerate
- Your doctor has already planned for you to have catheter ablation (a minimally invasive procedure to treat the irregular heartbeats)
- Able and willing to attend follow-up visits at 30 days and 90 days after the procedure

Other trials that look related to this one.
This trial tests a new method called pulsed field ablation to treat atrial fibrillation (AF), a type of irregular heartbeat. It aims to safely stop AF episodes by targeting specific areas in the heart, and may help people with paroxysmal (coming and going) or persistent AF who haven't had this procedure before.
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 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 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.
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 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.
