Outline of Final Research Achievements

In this study, the efficacy of prior Catheter ablation (CA) for prevent of recurrent AF after transcatheter ASD closure were assessed. We evaluated consecutive 52 patients (age, 67 ± 12 years) who complicated with paroxysmal or persistent AF before transcatheter ASD closure. Among them, 35 patients had been undergone CA for AF prior to ASD closure. During the follow-up period after ASD closure, recurrence of AF was observed in 3 of 35 (9%) with CA, contrary in 10 of 17 (59%) without CA (P< 0.001). Prior CA was an independent favorable parameter for AF free survival (p<0.01). Prior CA for AF is a valid therapeutic strategy for reducing the recurrence of AF after transcatheter ASD closure.
