Balloon cryoablation is a method for paroxysmal atrial fibrillation ablation that has developed as an alternative to radiofrequency ablation. The procedure is performed without a 3D mapping system, under X-ray control. A balloon with a diameter of 23 or 28 mm is placed at the ostium (mouth) of each pulmonary vein (heart usually has 4 of them) and then the inside of the balloon is cooled to -80 ᵒC. The potential benefits of cryoablation are shorter duration of the procedure in comparison to the radiofrequency ablation and the need for a single transseptal puncture. According to the results of studies done so far, success is similar to radiofrequency ablation.

Treatment is available also at the Department for Cardiovascular disease of the Sisters of Mercy University Hospital Centre, whose team on March 9th, 2015 performed the first two cryoablation (Dr. Pavlović, Dr. Manola, Dr. Radeljić)
