Intracardiac echo-guided radiofrequency catheter ablation of atrial fibrillation in patients with atrial septal defect or patent foramen ovale repair: a feasibility, safety, and efficacy study.
UNLABELLED Intracardiac Echo-Guided Radiofrequency Catheter . INTRODUCTION Patients with atrial septal defect ( ASD ) are at higher risk for  atrial fibrillation ( AF )  even after repair . Transseptal access in these patients is perceived to be difficult . We describe the feasibility , safety , and efficacy of pulmonary vein antral isolation ( PVAI ) in these patients . METHOD We prospect ively compared  post-ASD/patent foramen ovale ( PFO ) repair patients ( group I , n = 45 ) with age-gender-AF type matched controls ( group II , n = 45 ) . All the patients underwent PVAI through a double transseptal puncture with a roving circular mapping catheter technique guided by intracardiac echocardiography ( ICE ) . The short-term ( 3 months ) and long-term ( 12 month ) failure rates were assessed . RESULTS In group I , 23 ( 51 % ) had percutaneous closure devices and 22 ( 49 % ) had a surgical closure . There was no significant difference between group I and II in the baseline characteristics . Intracardiac echo-guided double transseptal access was obtained in 98 % of patients in group I and in 100 % of patients in group II . PVAI was performed in all patients , with right atrial flutter ablation in 7 patients in group I and in 4 patients in group II . Over a mean follow-up of 15 + /- 4 months , group I had higher short-term ( 18 % vs 13 % , P = 0.77 ) and long-term recurrence ( 24 % vs 18 % , P = 0.6 ) than group II . There was no significant difference in the perioperative complications between the two groups . Echocardiography at 3 months showed interatrial communication in 2 patients in group I and 1 patient in group II , which resolved at 12 months . CONCLUSION Percutaneous AF ablation using double transseptal access is feasible , safe , and efficacious in patients with ASD and PFO repairs
