Study of HeartLight during catheter ablation for irregular heartbeat

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 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 looks at whether a special heart rhythm treatment called “ablation” works well when done during certain heart operations. It may help reduce atrial fibrillation (AF) symptoms or future abnormal rhythm episodes for people who are already having surgery.

This study tracks results after a heart ablation procedure used to treat atrial fibrillation (an irregular heart rhythm). You may be asked to help by consenting and following the study plan so the researchers can better understand what happens after ablations.

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 whether pulsed-field ablation (a targeted treatment meant to stop abnormal heart signals) works better than a sham, or “placebo,” ablation. It is for certain people with atrial fibrillation (AF) to see if symptoms and heart rhythm outcomes improve.
