The purpose of this study is to evaluate major adverse bleeding risks, and thromboembolic event rates post radiofrequency (RF) ablation. The primary goal is to establish safety of dabigatran use for peri-procedural anti-coagulation after left atrial catheter radiofrequency ablation, or cryoablation procedures.

Condition Intervention Phase
Atrial Fibrillation
Atrial Flutter
Drug: dabigatran etexilate mesylate
Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Supportive Care
Official Title: Use of Dabigatran Etexilate to Prevent Stroke and Thromboembolism in Patients Undergoing Left Atrial Catheter Ablation Procedures for Paroxysmal or Persistent (Non-permanent) Atrial Fibrillation and Left Atrial Flutter

Primary Outcome Measures:
  • Frequency of major bleeding complications and thrombo-embolic events in patients administered dabigatran following RF ablation. [ Time Frame: Within 4 months following procedure (+/- 4 days) ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Dabigatran serum drug levels in patients experiencing a major bleeding or thrombo-embolic event. [ Time Frame: Within 4 months following procedure (+/- 4 days) ] [ Designated as safety issue: Yes ]
  • Frequency of minor bleeding events [ Time Frame: Within 4 months following procedure (+/- 4 days) ] [ Designated as safety issue: Yes ]
