| 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.
