Atrial Fibrillation Ablation: Radiofrequency or Cryoablation?

A Comparison of Radiofrequency Catheter Ablation With or Without Contact-force and Cryoablation for Paroxysmal Atrial Fibrillation Ablation

The study aims to compare 3 techniques routinely used for paroxysmal atrial fibrillation ablation: radiofrequency catheter ablation without contact-force, radiofrequency catheter ablation with contact-force and cryoablation. The hypothesis is the non-inferiority between the 3 techniques in terms of free-from atrial fibrillation survival (primary criteria). It will also compare lenght of procedure, radioscopy time and immediate complications (secondary criteria).

Inclusion Criteria:

• Patients who had an atrial fibrillation for symptomatic paroxysmal atrial fibrillation, refractory to antiarrhythmic drugs, between 01/01/2014 and 30/09/2017 in CHR Metz-Thionville

Exclusion Criteria:

• Patients not willing to participate via using their medical files
