Po-680-01 pulmonary vein reconduction patterns after index pulmonary vein isolation using radiofrequency or cryoballoon ablation: lower incidence of lspv-reconduction after cryoballoon ablation

Despite advances in safety and efficacy of pulmonary vein isolation (PVI), atrial fibrillation (AF) recurrence remains a common problem after PVI for rhythm-control treatment of AF. PV reconduction is frequently observed during AF reablation procedures. Several factors including patients’ anatomy and energy source predispose to electrical reconduction of PVs and might have an impact on patient management, e.g., to devote specific attention to certain veins during index procedures.
