Improved left atrial catheterization efficiency and consistency using a novel steerable transseptal puncture sheath.

Background: While steerable sheaths are widely used to improve catheter stability and contact force during radiofrequency (RF) catheter ablation in patients with atrial fibrillation (AF), steerable sheaths are less commonly used during transseptal puncture. This study evaluated whether left atrial catheterization efficiency can be improved using the VersaCross combined steerable sheath and transseptal system compared to previous standard workflow.

Methods: This study retrospectively analyzed AF ablation performed using the VersaCross Workflow consisting of VersaCross steerable sheath and RF wire for transseptal puncture and catheter ablation (VCW) to the standard workflow using a fixed curve sheath with RF needle followed by exchange for an Agilis steerable sheath for catheter ablation (STW).
