What this trial studies

The VISABL-AFL clinical investigation is a prospective, single-arm, multi-center trial aimed at evaluating the safety and efficacy of radiofrequency (RF) ablation for type-I atrial flutter. This procedure utilizes the Vision-MR Ablation Catheter 2.0 within an interventional Cardiac Magnetic Resonance (iCMR) environment. Patients eligible for this trial must have experienced at least one documented episode of atrial flutter in the past six months and be 18 years or older. The study will assess outcomes related to the effectiveness of the ablation technique in a controlled setting.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a documented history of type I atrial flutter.

Not a fit: Patients with contraindications for MRI procedures or those who have had recent cardiac events may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a safer and more effective treatment option for patients suffering from atrial flutter.

How similar studies have performed: Other studies have shown promising results with RF ablation techniques, suggesting potential success for this novel application in the iCMR environment.
