Overview

Retrospective analysis compares cooling gains and outcomes of POLARx and Arctic Front cryoballoon systems for atrial fibrillation.

Key Points

  • POLARx demonstrated superior cooling kinetics with lower nadir temperatures than Arctic Front.
  • Key metrics showed lower nadir at -57.6 °C with POLARx, versus -50.1 °C for Arctic Front.
  • Retrospective analysis of 200 patients underwent cryoballoon ablation for paroxysmal or persistent atrial fibrillation.
  • Both systems carried a similar rate of complications, highlighting comparable safety in procedures.
