Comparison between First- and Second-Generation Cryoballoon for Paroxysmal Atrial Fibrillation Ablation

Table 4

Comparison of lesion area between the first- and second-generation CryoBalloon catheter. Data obtained from electroanatomic mapping performed after cryoablation using the NavX system (St. Jude Medical, St. Paul, MN, USA).

Lesion area	CB, 1st	CB, 2nd
LPVs, cm^2 (mean SD)	68.2 44	75.3 26	0.61
RPVs, cm^2 (mean SD)	73.1 33	79.4 22	0.57

LPVs: left pulmonary veins; RPVs: right pulmonary veins.
