Comparing two techniques for treating persistent atrial fibrillation

Comparison Between VEin of MArshall Ethanol Infusion Versus Extended Pulmonary Vein PULSEd Field Ablation After Failed Pulmonary Vein Isolation in Patients with Persistent Atrial Fibrillation

Not applicable Interventional AZ Sint-Jan AV · NCT06383975

This study is testing two different ways to treat ongoing atrial fibrillation to see which method works better at keeping heart rhythms steady.

What this trial studies

This clinical trial aims to compare two different ablation techniques for patients suffering from persistent atrial fibrillation, a condition characterized by irregular and rapid heart rhythms. One technique uses pulsed field energy to create scars in the heart, while the other employs traditional radiofrequency ablation. Participants will undergo one of these procedures and will be monitored for one year to assess the effectiveness of each method in preventing the recurrence of atrial fibrillation. Regular check-ups and heart rhythm monitoring will be conducted to gather data on the outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals experiencing symptomatic persistent atrial fibrillation despite having undergone a previous pulmonary vein isolation procedure.

Not a fit: Patients with persistent atrial fibrillation lasting more than 12 months or those with significant heart conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients with persistent atrial fibrillation, potentially reducing the recurrence of their condition.

How similar studies have performed: Other studies have shown promise with similar ablation techniques, but this specific comparison of pulsed field ablation and ethanolization is relatively novel.
