NCT02696226

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Leaflet Motion

    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).

    4-6 weeks post procedure

Study Arms (4)

SAVR Warfarin Arm

EXPERIMENTAL

Warfarin arm-(target INR of 2-3)

Drug: SAVR Warfarin

TAVR Warfarin and Clopidogrel Arm

EXPERIMENTAL

Warfarin (target INR of 2-3) and Clopidogrel (75mg/day) arm

Drug: TAVR Warfarin and clopidogrel

SAVR Aspirin Arm

EXPERIMENTAL

Aspirin arm (81mg/day)

Drug: SAVR Aspirin

TAVR Aspirin and Clopidogrel Arm

EXPERIMENTAL

Aspirin (81mg/day) and Clopidogrel (75mg/day) arm

Drug: TAVR Aspirin and clopidogrel

Interventions

Warfarin treatment for 12 weeks with a target INR of 2-3 Warfarin treatment to begin on postoperative day 1-3 according to the patient's clinical status When warfarin treatment is discontinued, patients will be treated according to standard of care (aspirin 81 mg/day) indefinitely

Also known as: Coumadiin
SAVR Warfarin Arm

Aspirin (81 mg/day) to begin within 1-3 postoperative days according to the patient's clinical status and continue indefinitely per standard of care.

Also known as: Aspirin
SAVR Aspirin Arm

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
TAVR Warfarin and Clopidogrel Arm

Aspirin (81 mg/day) and clopidogrel (75 mg/day) in periprocedural period and continue for 24 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: Plavix
TAVR Aspirin and Clopidogrel Arm
