ABLATE Persistent is a prospective, non-randomized multi-center clinical trial to demonstrate the safety and effectiveness of the AtriCure Bipolar System for treating persistent atrial fibrillation during concomitant on-pump cardiac surgery.

Condition Intervention Phase
Atrial Fibrillation Device: AtriCure Bipolar System Phase 3

Study Type: Interventional

Further study details as provided by AtriCure, Inc.:

Primary Outcome Measures:
  • The primary efficacy endpoint for this study is the percent of patients free from AF and off Class I and III antiarrhythmic drugs at 9 months.
  • The primary safety endpoint is the composite acute major adverse event rate, within 30 days post-procedure or hospital discharge

Secondary Outcome Measures:
  • The secondary efficacy endpoint for this study is the percent of patients free from AF, independent of antiarrhythmic drug status at 9 months
  • The secondary safety endpoint is the composite 9-month post-procedure major adverse event rate.
