In this video, filmed at ACC 2018, Professor John Camm and Dr Michael Ezekowitz discuss the case of a 78-year old male with well-controlled hypertension who presented to the emergency department with palpitations. Discover the anticoagulation approach taken for this patient after an EKG confirmed atrial fibrillation and a cardioversion was planned. The risks and benefits of warfarin versus non-vitamin K oral anticoagulants (NOACs) are also explored, before an in-depth discussion into the optimal NOAC dosage before and after cardioversion.

  • Target audience
    This educational activity is designed for hospitalists, haematologists, interventional cardiologists, internists/physicians, surgeons and any other healthcare professional with an interest or role in the management of patients on anticoagulation undergoing cardioversion for atrial fibrillation.
  • Learning objectives
    After completing this educational activity, participants should be able to:
    • Understand the rationale for using non-vitamin K antagonist oral anticoagulants (NOACs) as anticoagulation therapy for cardioversion in patients who present with early onset atrial fibrillation (AF)
    • Select optimal NOAC dosage before and after cardioversion based on clinical and patient parameters
    • Recall the key trials evaluating NOACS in patients undergoing cardioversion for AF: dabigatran (RE-LY); rivaroxaban (X-VeRT); apixaban (EMANATE); and edoxaban (ENSURE-AF)
