Key result
Fluoroless ablation guided by late-activation mapping achieves ~95% initial success in AVNRT.
Why the study?
As practice trends toward fluoroless catheter ablation for AVNRT, easily obtained and reproducible methods for slow-pathway identification and ablation are increasingly needed.
Does mapping-system detection of late-activation, low-amplitude voltage during sinus rhythm allow for successful fluoroless ablation of the slow pathway in patients with AVNRT?
Observational (n=41)
No
Does mapping-system detection of late-activation, low-amplitude voltage during sinus rhythm allow for successful fluoroless ablation of the slow pathway in patients with AVNRT?
Mapping-system detection of late-activation, low-amplitude voltage during sinus rhythm provides an objective and highly successful method for fluoroless slow-pathway ablation in typical AVNRT.

May support fluoroless AVNRT ablation in experienced centers; leaves open need for randomized confirmation.
Hale et al. (2020) conducted an observational in Atrioventricular nodal reentrant tachycardia (AVNRT) (n=41). Fluoroless ablation using mapping-system detection of late-activation, low-amplitude voltage was evaluated on Initial ablation success. Fluoroless ablation using mapping-system detection of late-activation during sinus rhythm achieved initial success in 95% (39/41) of AVNRT cases.
