One Year Incidence of Atrial Septal Defect after PV Isolation: A Comparison Between Conventional Radiofrequency and Cryoballoon Ablation

Abstract

the incidence of IASD at 1-year follow-up following CB ablation procedure for PVI is significantly higher with respect to RF procedures. Although no adverse clinical events were recorded in patients with persistence of IASD, more detailed echocardiographic examinations might be advised in all individuals exhibiting this finding.
