Abstract
The existence of pulmonary vein (Pv) common ostia in pts with atria1 fibrillation (AF) could suggest a more complex and arrhythmogenic substrate. The aim of this study was to evaluate the prevalence and signiiicance of this anatomic variant in AF pts. Methods: We considered 43 pts (33 males; age 53S p<O.OOOl). EI of arrhythmogenic and non-mhythmogenic PVs (except the right inferior PV that was treated only if involved in arrhyhnogenesis) was achieved with a mean radiofrequency energy delivery of 21&18 min. At a mean follow-up of 5.5&3 months, AF recurred (without antr p: IX). Conclusions: A PV common ostium is frequently documented in pts with AF. Since it is often involved in arrhythmogenesis, it represents a major target for PVEI procedures. Longer follow-up data are required to assess the clinical relevance of this finding.
