Why the study?
Does biatrial mapping and extensive ablation restore sinus rhythm in a patient with refractory persistent AF with very short cycle length?
Does biatrial mapping and extensive ablation restore sinus rhythm in a patient with refractory persistent AF with very short cycle length?
Extensive biatrial ablation may be effective for restoring and maintaining sinus rhythm in patients with refractory persistent AF characterized by very short cycle lengths.
May support extensive biatrial ablation in refractory persistent AF with short cycle lengths; hypothesis-generating and requires prospective validation.
We present a case of a 36-year-old woman with highly symptomatic persistent atrial fibrillation (AF) refractory to sotalol, flecainide, and external direct current (DC) cardioversion. The patient underwent biatrial mapping and ablation procedure for AF. Both atria were characterized by refractory properties which were much shorter than reported previously. Global fibrillatory activity was present with a median cycle length of 120 ms (range: 62-143). Extensive map-guided ablation sets had to be delivered to both left and right sides before effective DC cardioversion enabled sinus rhythm (SR) restoration. The patient remained in SR at 9 months of follow-up.
