Yes, Xarelto (rivaroxaban) can be given on the morning of cardioversion
Rivaroxaban should be continued on the morning of cardioversion as part of an uninterrupted anticoagulation strategy, provided the patient has been on therapeutic anticoagulation for at least 3 weeks prior to the procedure 1.
Key Requirements Before Cardioversion
The 2024 ESC Guidelines establish clear anticoagulation requirements:
- Therapeutic oral anticoagulation for at least 3 weeks (with documented adherence to DOACs) is mandatory before scheduled cardioversion 1
- Direct oral anticoagulants like rivaroxaban are preferred over warfarin for patients undergoing cardioversion 1
- Continue anticoagulation for at least 4 weeks after cardioversion, and long-term if thromboembolic risk factors persist 1
Timing and Dosing on Procedure Day
Continue rivaroxaban on the morning of cardioversion without interruption. The X-VeRT trial, which established rivaroxaban's safety and efficacy for cardioversion, used uninterrupted rivaroxaban (20 mg once daily, or 15 mg if creatinine clearance 30-49 mL/min) including on the procedure day 2. This approach showed:
- Similar rates of stroke and thromboembolic events compared to warfarin (0.51% vs 1.02%)
- Similar bleeding rates (0.6% vs 0.8%)
- Significantly shorter time to cardioversion compared to warfarin (p<0.001) 2
Real-world data confirms that uninterrupted rivaroxaban taken preoperatively for AF ablation (a more invasive procedure than cardioversion) is clinically effective and safe 3.
Clinical Algorithm
- Verify 3-week therapeutic anticoagulation: Confirm patient adherence to rivaroxaban for ≥3 weeks
- Give morning dose: Administer rivaroxaban on the morning of cardioversion at the usual time
- Proceed with cardioversion: No need to delay or check specific anticoagulation levels
- Continue post-procedure: Resume regular dosing schedule after cardioversion
Exception: Early Cardioversion (<48 hours)
If AF duration is definitively <48 hours, cardioversion can be performed without the 3-week anticoagulation requirement 4. However, anticoagulation should still be initiated and continued for at least 4 weeks post-procedure 1.
Important Caveats
- TEE alternative: If 3 weeks of therapeutic anticoagulation has not been achieved, transoesophageal echocardiography to exclude thrombus is required before early cardioversion 1
- Never cardiovert without anticoagulation if AF duration >24 hours or is unknown, unless TEE excludes thrombus 1
- The standard rivaroxaban dose for AF is 20 mg once daily (15 mg if CrCl 30-49 mL/min) - do not use the 10 mg dose, which is inferior in effectiveness 5
