Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 75 with a documented history of atrial fibrillation who are scheduled for an AF catheter ablation procedure.

Probably not a fit

Patients with contraindications to open heart surgery, active systemic infections, or significant heart failure may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the safety and effectiveness of the Globe Mapping and Pulsed Field Ablation System for patients with atrial fibrillation (AF). Participants will undergo a catheter ablation procedure using this innovative technology, which aims to improve treatment outcomes for AF. The study will collect clinical data to assess how well the device performs in a real-world setting. It targets individuals who have a documented history of AF and are between the ages of 18 and 75.

Why it matters

Potential benefit: If successful, this approach could lead to improved treatment options for patients suffering from atrial fibrillation.

How similar studies have gone: Other studies have shown promise with similar ablation techniques, but the specific use of the Globe Mapping and Pulsed Field Ablation System is relatively novel.
