Question

A 35-year-old woman with a mechanical mitral valve has chronic atrial fibrillation. She asks whether she can change from warfarin to a newer direct oral anticoagulant. Her renal and liver function are normal. What is the most appropriate response?

Switch warfarin to apixaban as it has fewer food interactions

Answer

Switch warfarin to rivaroxaban because a once-daily dose improves adherence

Answer

Stop anticoagulation and use aspirin alone

Answer
