Successful left atrial access through GORE CARDIOFORM ASD occluder using an integrated transseptal wire system after failed RF needle approach

Abstract

An integrated transseptal wire system enabled successful left atrial access through the elastic resistance posed by a large GORE CARDIOFORM ASD occluder after failed RF needle attempt, allowing large-bore cryoballoon sheath advancement via sequential sheath technique for atrial fibrillation ablation without procedural complications.
