Abstract Background The novel fourth‐generation cryoballoon (CB4) potentially allows for enhanced catheter maneuverability and more frequent capture of pulmonary vein (PV) potentials which can be used to monitor real‐time PV isolation (PVI). aim our study is compare the acute procedural endpoints between CB4 second‐generation (CB2). Methods A single‐center retrospective chart review was examine 50 consecutive patients with drug‐refractory atrial fibrillation undergoing CB4‐based PVI. Procedural data success these were compared propensity‐matched controls who underwent ablation procedure using CB2. Results Procedures performed showed significant shorter fluoroscopy time (14.8 ± 5.5 vs 18.0 6.5 minutes, P = .04), (58.3 15.7 65.3 21 .13), total (10.8 1.5 13.8 1.9 .42). PVI visualization rate 33.3% in CB2 group 74.7% ( < .001). correlated increase recordings regard all single (left superior PV: 58% 84%, .02; left inferior 26% 71%, .001; right 29% 61%, .01; 19% 58%, .002). Conclusion often able subsequent isolation.
