  • During the initial AF ablation procedure ONLY pulmonary vein isolation / ablation will have been performed
  • Documented recurrence of AF lasting more than 30 seconds after the first ablation procedure.
  • With the ability and willingness to sign the informed consent of the patient.
  • With a minimum follow-up capacity of 12 months.

Exclusion criteria

  • Patients aged <18 years.
  • Previous heart surgery.
  • Moderate or severe mitral valve disease.
  • Severe dilation of the left atrium, defined as a volume greater than 48 ml / m2 or a left atrial diameter greater than 50 mm in the parasternal long axis.
  • Contraindication for anticoagulation.
  • Pregnancy or pregnancy intention during the 12-month follow-up.
  • Life expectancy less than 12 months.
