In group A, 20\/20 (100%) right superior (RSPV) and inferior (RIPV) PVs, 18\/19 (95%) left superior (LSPV) and inferior (LIPV) PVs, and 1\/1 (100%) left common ostium (LCPV) were successfully isolated. First\u2010pass success rate was 95%, 85%, 68%, and 95% for the RSPV, RIPV, LSPV, and LIPV, respectively. Touch\u2010up radiofrequency ablation was required in 1\/19 (5%) LSPV and LIPV. In group B, an attempt at circumferential PVI was feasible in 2\/18 (11%) septal PVs and successful on first pass.
