Evaluating new technologies for successful atrial fibrillation ablation

Advanced TecHnologies For SuccEssful AblatioN of AF in Clinical Practice: ATHENA Study

Observational Azienda Ospedaliero, Universitaria Pisana · NCT05617456

This study is testing how well a common heart procedure called catheter ablation works for people with atrial fibrillation over a year to see if it helps keep their heart rhythm steady.

What this trial studies

This observational study aims to evaluate the effectiveness of catheter ablation for atrial fibrillation (AF) in a large population over a 12-month follow-up period. It will collect data on clinical outcomes, including recurrence of AF and other atrial arrhythmias, as well as adverse events. The study will analyze up to 20 clinical and procedural parameters to identify predictors of long-term success in AF ablation. Patients will be treated according to standard care protocols at participating centers.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with an indication for AF ablation according to current guidelines.

Not a fit: Patients currently enrolled in other investigational studies that may interfere with this study will not benefit.

Why it matters

Potential benefit: If successful, this study could improve the long-term outcomes of patients undergoing ablation for atrial fibrillation.

How similar studies have performed: Previous studies have shown success with catheter ablation techniques for atrial fibrillation, making this approach well-established.

Inclusion Criteria:

* Patients with an indication to an ablation procedure of Atrial Fibrillation according to current international and local guidelines (and future revisions), existing IFU and per physician discretion
* Patients who are willing and capable of providing informed consent, participating in all testing at an approved clinical investigational center.
* Patients whose age is 18 years or above, and of legal age to give informed consent specific to state and national law.
