Differences between 2 cryoballoon systems in achieving successful pulmonary vein isolation in patients with challenging anatomies.

ABSTRACT:

Background

A new technology, the POLAR cryoballoon system, was designed to enhance maneuvering and stabilizing catheter positions with a softer balloon and more deflectable sheath. These novel characteristics may help achieve successful pulmonary vein (PV) isolation in difficult cases when conventional balloons were used.

Objective

This study aimed to investigate the differences in the lesion profiles, touch-up radiofrequency ablation (RFA) rate, and anatomical predictors of acute PV isolation between the POLAR and Arctic Front Advance Pro (AFA-Pro).

Methods

This retrospective study included 338 consecutive patients who underwent a first cryoballoon ablation for paroxysmal atrial fibrillation at Keio University Hospital from April 2019 to September 2023. Using propens
