Key result
Left pulmonary vein ablation is linked to ~174% higher pain odds versus the right inferior vein.
Why the study?
Does the location of radiofrequency ablation of pulmonary veins correlate with pain sensation in patients with atrial fibrillation?
Population
46 patients with atrial fibrillation undergoing radiofrequency ablation of pulmonary veins.

Left PV ablation associated with more pain; hypothesis-generating for site-specific analgesia strategies during AF ablation.

Does the location of radiofrequency ablation of pulmonary veins correlate with pain sensation in patients with atrial fibrillation?
Odds Ratio: 2.74 (95% CI 1.79–4.19)
p-value: p=< 0.001
Pain during radiofrequency ablation of pulmonary veins is common and more frequently associated with ablation of the left inferior and left superior pulmonary veins, independent of esophageal location.
Alaeddini et al. (2007) conducted an observational in Atrial Fibrillation (n=46). Radiofrequency ablation of left inferior pulmonary vein vs. Radiofrequency ablation of right inferior pulmonary vein was evaluated on Production of pain during ablation (OR 2.74, 95% CI 1.79-4.19, p=< 0.001). Radiofrequency ablation of the left inferior (OR 2.74; 95% CI 1.79-4.19; P<0.001) and left superior pulmonary veins was significantly more likely to produce pain compared to the right inferior vein.
