Efficacy of temperature-guided cryoballoon ablation without using real-time recordings - 12-Month follow-up.

Background: We sought to evaluate a temperature-guided approach of cryoballoon (CB) ablation without visualization of real-time recordings.

Methods And Results: We analysed 166 patients (34.9% female, 60 ± 11 years) with paroxysmal or short-term persistent atrial fibrillation (AF).
