Discussion
One hundred and thirty patients who underwent VGLA using the first
generation LB were analyzed in the present retrospective single center
study. The main findings of our study were as follows: (1) we could
successfully isolate the LCPVs at the ostium with only the VGLA in 9/11
patients (81.8%), (2) the total procedure time was significantly
shorter in the patients with an LCPV than in those without (174.9 ± 31.6
min vs. 148.2 ± 19.9 min, P < 0.01), and (3) the presence and
configuration of the LCPV was not a significant predictor of any atrial
tachyarrhythmia recurrence after the ablation procedure.
