This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing a new ablation procedure called pulsed field ablation (PFA) combined with advanced heart mapping to treat persistent atrial fibrillation—a condition where your heart rhythm becomes irregular and difficult to control. Unlike older approaches that only target the pulmonary veins, this treatment uses special mapping technology to find and treat additional abnormal electrical areas throughout the heart. It's designed for patients with long-standing atrial fibrillation who haven't responded well to standard treatments, especially those with heart failure or other serious health conditions.
Most current ablation treatments for long-standing atrial fibrillation only work partially, leaving many patients still dealing with irregular heartbeats—especially those with heart failure or multiple health problems. Doctors need better strategies to find and treat all the abnormal electrical areas in the heart, not just a few spots, and this trial is testing whether a more comprehensive approach can help patients who haven't benefited from conventional treatment.

If you join this study, you'll first have a small heart monitor inserted under your skin to track your heart rhythm continuously. Then you'll undergo the ablation procedure, which involves inserting thin tubes into blood vessels and using advanced mapping technology to identify problem areas in your heart before treating them with the new pulsed field ablation technique. You'll be monitored during and after the procedure, and the research team will check on your progress regularly to see how well the treatment works for you.
