Long-term results and the predictors of outcome of catheter ablation of atrial fibrillation using steerable sheath catheter navigation after single procedure in 674 patients

Abstract

In our patients' cohort, a single catheter ablation procedure based on CPVA using steerable sheath for catheter navigation resulted in a 1 year success rate of 75.7% [without (91.0%) and with (58.6%) early recurrence, respectively, P = 0.0001]. Among those patients who are at high risk for recurrence after CPVA other ablation endpoints rather than completion of predefined lesions might be necessary to increase the success rate.
