The novel cryoballoon Advance (CB-A) has proven to achieve significantly lower temperatures and faster pulmonary vein isolation (PVI) times in comparison with the first-generation device. Although acutely very effective, best of our knowledge, data on mid-term clinical follow-up is lacking.The aim study was analyse freedom from recurrence atrial fibrillation (AF) a 1-year period, series consecutive patients having undergone PVI CB-A for paroxysmal AF (PAF).Forty-two [30 male (71%); mean age: 57.9 ± 21.1 years] were included. All underwent procedure large 28 mm CB-A. A total 168 PVs depicted pre-procedural computed tomography scan.
