Aim: We examined the change of body temperature during ablation therapy for atrial fibrillation with either cryoballoon (CB) or radiofrequency (RF) catheters.
Methods and Results: We retrospectively examined 18 patients who underwent CB ablation (CB group) and 18 patients who underwent RF ablation (RF group) for pulmonary vein isolation using propofol for their sedation during procedure. While body temperature at the entry into the cardiac catheterization laboratory was similar between the two groups, the body temperature at the exit of laboratory was lower in the CB group than the RF group (p=0.001). The difference of body temperature between entry and exit was 1.6℃ and 0.9℃, in the CB group and the RF group, respectively, and this difference between the two groups was statistically significant (p<0.001).
Conclusions: The CB ablation decreased the body temperature significantly more than the RF ablation during procedures when patients were sedated with propofol.
