Pulmonary vein isolation is the main treatment of paroxysmal and persistent atrial fibrillation.
The aim of our study is to prospectively compare the efficacy and safety of the 3 options of radiofrequency delivery with QDOT Micro™, with systematic use of catheter stabilization tools and tighter lesions
Patient aged 18 or over

Paroxysmal atrial fibillation defined as atrial fibrillation lasting less than 48 hours
Early atrial fibrillation defined as atrial fibrillation lastiing between 7 days and 3 months
History of atrial fibrillation ablation (surgery or catheter)
Documented left atrial thrombus
Left atrial (LA) diameter > 60mm / LA area > 35cm2 / Left atrial volulme index (LAVI) > 45ml/m2
