Read our Atrial Fibrillation research guide →Phase 3 — Testing in thousands of people, comparing the treatment against what doctors currently use. This is the last big step before approval.
This trial is testing a new heart procedure called pulsed-field ablation to treat atrial fibrillation — a condition where your heart's upper chambers beat irregularly. Half of the participants will receive the actual pulsed-field ablation procedure, while the other half will receive a sham procedure (no actual ablation) so researchers can fairly compare how well this treatment works. The study will measure whether the real procedure helps you stay in normal heart rhythm and improves your quality of life.
Atrial fibrillation can cause symptoms like shortness of breath, fatigue, and chest discomfort. Doctors need to know whether this new energy-based ablation technique works better than we currently understand, which is why researchers are carefully comparing it to a sham procedure to prove it's truly effective.

You will have a small monitoring device implanted under your skin within the first week. About a month later, you'll undergo an initial heart study to check for other rhythm problems. If you qualify, you'll be randomly assigned to either receive the pulsed-field ablation procedure or the sham procedure. Both procedures take about 20–30 minutes under anesthesia. After your procedure, you'll have a two-month period where your heart rhythm may naturally improve, followed by monitoring and quality-of-life assessments at 6 months to see how well the treatment worked.
