Objective:
To investigate the efficacy and safety of circumferential pulmonary vein ostial isolation guided by EnSite NavX three-dimensional electrophysiological mapping in patients with atrial fibrillation (AF).
Methods:
Thirty-eight patients with drug refractory paroxysmal or persistent AF underwent circumferential pulmonary vein ostial isolation and were followed up to investigate the efficacy and safety of the treatment.
Results:
All cases reached the endpoint of the ablation, and both sides of the pulmonary vein were completely isolated, with an average procedure time of 200.4-/+37.0 min, X-ray exposure time of 54.7-/+9.7 min, and three-dimensional left atrial geometry reconstruction time of 27.5-/+7.5 min. During the follow-up for 9-/+3 months, the success rate of initial ablation was 89.5%, and the incidence of procedure-related complications were 7.9%.
Conclusions:
Circumferential pulmonary vein ostial isolation guided by EnSite NavX three-dimensional electrophysiological mapping can be effective and safe for AF treatment.
