BMI = body mass index; LA = left atrium; LCPV = left common pulmonary
vein; HR = hazard ratio; CI = confidence interval.

Figure 1. An example of a voltage map of the left atrium and
pulmonary veins before and after the PVI (purple area; a voltage of more
than 0.5 mV, gray area; a voltage of less than 0.1 mV). The distance
between the LCPV ostium and bifurcation was 18mm. The LCPV was
successfully isolated with an LB inserted into the LCPV superior branch.
PVI = pulmonary vein isolation; LCPV = left common pulmonary vein;
LB = laser balloon.
Figure 2. Long-term freedom from atrial tachyarrhythmia
recurrence after an initial VGLA guided PVI.
VGLA = visually guided laser ablation; PVI = pulmonary vein isolation.
