Results:
Eleven patients (8.5%) had an LCPV (ostium maximal average diameter: 27.5 ± 4.9 mm, ostium minimal average diameter: 17.7 ± 3.5 mm). Nine out of 11 (81.8%) LCPVs were successfully occluded and isolated at the ostium with a VGLA guided PVI. The ablation procedure time was significantly shorter in the patients with than without an LCPV (61.5 ± 15.4 vs. 86.9 ± 32.9 min, p = 0.01). There was no difference regarding the atrial tachyarrhythmia recurrence between those with and without an LCPV (p = 0.18). A total of fifteen patients underwent a redo procedure, but reconnections were not observed in any of the LCPV patients.
