Key result
Temperature-guided slow AV nodal pathway ablation significantly reduced mean ablation time (19.9 vs 30.9 min, P<=0.02) and prevented coagulum formation compared to non-temperature-guided ablation.
Why the study?
Does temperature-guided slow AV nodal pathway ablation improve procedural times and prevent coagulum formation compared to non-temperature-guided ablation in patients with symptomatic AVNRT?

Absolute Event Rate: 19.9% vs 30.9%
p-value: p=<=0.02
Temperature-guided slow AV nodal pathway ablation is safe, effective, and reduces fluoroscopy and ablation times while preventing coagulum formation compared to non-temperature-guided ablation.

May shorten AVNRT ablation times without coagulum; hypothesis-generating until randomized confirmation.
Epstein et al. (1997) conducted a cohort in symptomatic AV nodal reentrant tachycardia (AVNRT) (n=82). Temperature guided slow AV nodal pathway ablation vs. Nontemperature guided slow AV nodal pathway ablation was evaluated on mean ablation time (minutes) (p=<=0.02). Temperature-guided slow AV nodal pathway ablation significantly reduced mean ablation time (19.9 vs 30.9 min, P<=0.02) and prevented coagulum formation compared to non-temperature-guided ablation.
