Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Prospective assessment of vitamin K dependent coagulation factor levels after temporary warfarin reversal in participants with left ventricular assist devices (LAVD).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Prospective evaluation of the levels of the vitamin K dependent coagulation factors 2,7,9,10, and proteins C and S, in patients on warfarin treated with four factor prothrombin complex concentrate (4F-PCC). Participants on vitamin K antagonists (VKA) such as warfarin have suppressed levels that are brought to the normal range with treatment with 4F-PCC to reverse the warfarin effect. The investigators will assess the duration of effect of 4F-PCC on these factor levels in participants with left ventricular assist devices (VAD) requiring temporary reversal of warfarin for invasive procedures that have a risk of bleeding. The investigators will also assess the time to return to therapeutic INR..

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Treatment

Based on starting international normalized ratio (INR) and target INR, the dose of four factor prothrombin complex concentrate will be calculated and infused. Coagulation factor levels will be assessed over 48-72 hours.

Group Type EXPERIMENTAL

four factor prothrombin complex concentrate

Intervention Type DRUG

After treatment with 4F-PCC, coagulation factor levels will be assessed. Time to return to anticoagulation target INR will also be determined.
