The POLAR-WAVE registry is a prospective, multi-center, single-arm study evaluating the efficacy and safety of pressure-guided atrial fibrillation cryoablation, where the occlusion of pulmonary veins will be assessed by pressure waveforms (instead of contrast), over a follow-up period of 12 months.~This is a non-commercial, investigator-driven clinical study, coordinated by the main investigator from University Hospital 12th of October, Madrid, Spain. Several responsibilities are delegated to the Clinical Research Unit (University Hospital 12th of October, Madrid, Spain).~The study was planned according to the Good Clinical Practices. POLAR-WAVE Study has been approved by the Ethics Committee and Spanish Health Authorities. All participating patients must give written informed consent.
