Descriptive Information
Brief Title  ICMJE Use of Protamine for Heparin Reversal After Catheter Ablation of Atrial Fibrillation
Official Title  ICMJE Use of Protamine for Heparin Reversal After Catheter Ablation of Atrial Fibrillation: A Randomized Trial
Brief Summary The objective of this study is to evaluate the safety, efficacy and efficiency of rapid anticoagulation reversal with protamine sulfate versus routine activated clotting time (ACT) monitoring in patients undergoing catheter based ablation of atrial fibrillation.
Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 4
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE
  • Atrial Fibrillation
  • Catheter Ablation
Intervention  ICMJE Drug: Protamine Sulfate
Protamine sulfate is a highly basic protein that forms stable compounds with acidic heparin to rapidly neutralize the anticoagulation effects.
Study Arms  ICMJE
  • No Intervention: Control
    Patients in the control arm will undergo routine post-procedure management prior to removal of vascular sheaths. This includes routine measurements of ACT beginning 90 min after the cessation of the procedure with a goal ACT of <200s or return to pre-procedural baseline prior to sheath removal.
  • Active Comparator: Protamine
    Patients in the active comparator arm will receive protamine sulfate for rapid reversal of heparin prior to sheath removal. They will first receive a small test dose with close hemodynamic monitoring followed by therapeutic dose if no reaction occurs.ACT levels will then be monitored with a goal ACT of <200s or return to preprocedural baseline prior to removal of vascular sheaths.
    Intervention: Drug: Protamine Sulfate
