Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older who are scheduled for catheter ablation due to symptomatic paroxysmal atrial fibrillation and have failed at least one anti-arrhythmic drug.
✕Probably not a fit
Patients who are in overall good health and do not meet the criteria for symptomatic paroxysmal atrial fibrillation may not benefit from this study.

What this trial studies
This post-approval study aims to assess the clinical outcomes of patients treated with the HeartLight System for drug refractory, symptomatic, paroxysmal atrial fibrillation. It is a prospective, open-label, multi-center, single-arm study designed to confirm the safety and effectiveness of the HeartLight System during its commercial use. Participants will be monitored to evaluate the long-term results following catheter ablation procedures. The study seeks to provide additional data following a pivotal clinical study that initially validated the device's efficacy.
Why it matters
Potential benefit: If successful, this study could provide a more effective treatment option for patients suffering from atrial fibrillation who have not responded to medication.
How similar studies have gone: Other studies have shown success with similar ablation approaches for atrial fibrillation, indicating a promising avenue for treatment.
