简要总结

The purpose of this study is to determine the best strategy to manage novel oral anti-coagulants (NOACs) at the time of pacemaker or defibrillator surgery. The Investigators hypothesize that performing device surgery without interruption of the novel oral anti-coagulant will result in a reduced rate of clinically significant hematoma.

详细描述

This is a prospective, open-label, randomized trial, with 1:1 randomization to either continued NOAC or interrupted NOAC in patients with non-rheumatic atrial fibrillation or atrial flutter and at moderate to high risk of arterial thrombo-embolic events who require device surgery.

All patients in the study will be receiving Dabigatran or Rivaroxaban or Apixaban for at least 5 days prior to enrollment. The peri-operative management of the NOAC the patient is receiving is randomized to Interrupted NOAC or Continued NOAC.

Interrupted NOAC arm:

  1. Interrupted Dabigatran
  • based on renal function, patients will discontinue Dabigatran 1 day before surgery if GFR > 50 mL/min, and 2 days before surgery if GFR is 30-50 mL/min.
  • Dabigatran will be resumed at the next regular dose time, > or = 24 hours after the end of surgery.
  1. Interrupted Rivaroxaban

结局指标

主要结局

Clinically significant hematoma

时间窗: 2 weeks post-op or until resolution of hematoma

Defined as: 1. Hematoma requiring re-operation - Defined as a hematoma that continues to expand despite all appropriate non-operative measures, or is producing impending or actual wound breakdown or skin necrosis. Minor hematomas that are evacuated at the time of other re-operation (eg. for lead repositioning) are not considered as a primary outcome. or 2. Hematoma resulting in prolongation of hospitalization - Defined as extended hospitalization or rehospitalization for \> 24 hours, post index surgery, primarily due to hematoma. or 3. Hematoma requiring interruption of anti-coagulation. - Defined as reversal or intentional withholding of all anticoagulation for \> or = 24 hours, in response to wound hematoma.

次要结局

  • Composite of major peri-operative bleeding events and thrombo-embolic events(2 weeks post-op)
