One Year Incidence of Iatrogenic Atrial Septal Defect After Cryoballoon Ablation for Atrial Fibrillation

Abstract

IASD after CB ablation of AF is present in up to 20% of patients after 1 year. Although no adverse clinical events were recorded in patients with persistence of IASD, this complication should not be underestimated and systematic echocardiographic examinations might be advised at regular intervals in the follow-up period after CB. Further studies with larger population and follow-up might be required to confirm our findings.
