## TL;DR

A new method using an integrated transseptal wire system successfully accessed the left atrium after a failed RF needle attempt during a heart procedure.

## Contribution

The use of an integrated transseptal wire system for accessing the left atrium through a large occluder is novel and effective.

## Key findings

- The integrated transseptal wire system overcame the elastic resistance of the GORE CARDIOFORM ASD occluder.
- A large-bore cryoballoon sheath was advanced successfully using the sequential sheath technique.
- The procedure was completed without complications for atrial fibrillation ablation.

## 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.
