Evaluating high power short duration RF for atrial fibrillation ablation

Atrial Fibrillation Ablation by Means of Very High Power Short Duration (AIR HPSD Registry)

Observational Clinica Mediterranea · NCT05777551

This study is testing a new way to use radiofrequency energy for heart ablation to see if it helps people with atrial fibrillation feel better and stay healthy over the next year.

What this trial studies

This observational study aims to assess the safety and efficacy of pulmonary vein isolation using high power short duration radiofrequency energy in patients with paroxysmal or persistent atrial fibrillation. Participants will undergo catheter ablation with commercially approved devices and will be followed for 12 months to monitor the recurrence of atrial fibrillation and identify predictors of outcomes. The study plans to enroll at least 850 patients to ensure adequate statistical power for analyzing the primary endpoint, which focuses on the relationship between clinical characteristics and the effectiveness of the procedure.

Who should consider this trial

Good fit: Ideal candidates include patients with paroxysmal or persistent atrial fibrillation who are on active oral anticoagulation.

Not a fit: Patients who have previously undergone ablation for atrial fibrillation or have significant heart failure may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved outcomes and reduced recurrence rates for patients with atrial fibrillation.

How similar studies have performed: While this approach is being evaluated in this study, similar techniques have shown promise in other studies, suggesting potential for success.
