This is a prospective, randomized pilot study in patients undergoing Sugical Aortic Valve Replacement (SAVR) and Transcatheter Aortic Valve Replacement (TAVR) to estimate the incidence of reduced leaflet motion and assess the impact of perioperative anticoagulation on the incidence of reduced leaflet motion.

Study Timeline
Dates and qualifiers reported by the registry. Estimated dates do not confirm that a milestone has occurred.
Frequency of reduced leaflet motion related to perioperative anticoagulation with warfarin as measured by 4DMCT data. (\<50% reduction in motion), moderately reduced (50 to 70% reduction), severely reduced (\>70% reduction), or immobile (lack of motion of at least one valve leaflet).

Grouped treatment entry
TAVR Warfarin and clopidogrel
The registry names several treatments. This does not confirm that participants received them together or that they form a single product.
Begin Warfarin and clopidogrel (75 mg/day) treatment within 1-3 days postop for 12 weeks with a target INR of 2-3 When warfarin is discontinued, begin aspirin (81 mg/day) and continue aspirin/clopidogrel for 12 weeks At 24 weeks, study treatment will end and patients will be treated according to standard of care (aspirin 81 mg/day) indefinitely
Also known as: Coumadin, Plavix
