Effect of a Bigger Cryoballoon on the Total Antral Lesion Size: Evaluation of POLARx FIT

Erasmus Medical Center·interventional·Posted May 31, 2023·Updated Dec 4, 2025

In Brief

A clinical study evaluating POLARx FIT cryoballoon for Atrial Fibrillation. Completed, enrolled 20 participants across 1 site.

Detailed Summary

The investigators will prospectively evaluate the extent of antral lesion created by the 31 mm balloon size of a novel cryoballoon catheter (POLARx FIT). In 20 patients with paroxysmal atrial fibrillation, the investigators will perform pre- and post-ablation high-definition 3D maps to quantify the extent of lesion created by the 31 mm POLARx FIT cryoballoon.
