We compared the single procedure success of CF\u2010guided pulmonary vein isolation (PVI) with that of non\u2010CF guided PVI during a 3\u2010year (1,095 days) follow up period and analyzed the pattern of pulmonary vein (PV) reconnection.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cohort of 167 subjects (68 CF vs. 99 non\u2010CF) with paroxysmal AF were included in the study.
