Key result
Pain during posterior wall RF ablation strongly predicts esophageal temperature rise in ~77% of cases.
Why the study?
The relationships between chest pain, esophageal temperature rise, and anatomical locations of radiofrequency ablation during pulmonary vein isolation were not well characterized.
Does chest pain during radiofrequency ablation predict esophageal temperature rise in patients undergoing pulmonary vein isolation?
Observational (n=40)
Does chest pain during radiofrequency ablation predict esophageal temperature rise in patients undergoing pulmonary vein isolation?
Absolute Event Rate: 77.4% vs 0.8%
p-value: p=<0.0001
Chest pain during radiofrequency ablation for pulmonary vein isolation under moderate sedation is a highly sensitive and specific predictor of esophageal temperature rise.
No takes yet. Share an insight, caveat, or question.
Pain during posterior wall ablation was associated with esophageal temperature rise; hypothesis-generating and should not yet change PVI practice.
Aryana et al. (2007) conducted an observational in Patients undergoing pulmonary vein (PV) isolation (n=40). Pain during radiofrequency ablation vs. Absence of pain during ablation was evaluated on Esophageal temperature rise (ETR) (p=<0.0001). Pain during posterior wall radiofrequency ablation strongly predicted esophageal temperature rise compared to pain-free applications (77.4% vs 0.8%; P<0.0001).
