What this trial studies

This clinical trial is a prospective, randomized, single-blind study that aims to compare two methods for guiding Vein of Marshall ethanol infusion (VOMEI) in patients with persistent or longstanding persistent atrial fibrillation. Participants will be randomly assigned to receive VOMEI either through conventional fluoroscopy guidance or through a combination of fluoroscopy and CARTO UNIVU guidance. The study will evaluate the efficacy of the procedures by measuring changes in low-voltage areas and will assess safety by monitoring procedural complications. Long-term outcomes will focus on the recurrence of atrial tachyarrhythmia over a period of 3 to 12 months.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 85 with persistent or longstanding persistent atrial fibrillation who are willing to undergo catheter ablation and VOMEI.

Not a fit: Patients with recent cardiac events, significant comorbidities, or contraindications to anticoagulation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the effectiveness and safety of atrial fibrillation treatments, potentially leading to better patient outcomes.

How similar studies have performed: While the specific approach of using UNIVU guidance for VOMEI is novel, similar studies have shown promise in improving procedural outcomes in atrial fibrillation treatments.
