Cryoballoon ablation was developed as a new treatment for pulmonary vein (PV) isolation and has demonstrated high procedural success and comforting long-term clinical outcome. However, some improvements are necessary for real-time visualization of PV signals that appeared important to increase the efficacy and reduce ineffective cryoapplications. We report, for the first time, a cryoablation procedure using the fourth-generation cryoballoon, describing betterment in vein signal recording and acute procedural success.
