actually the patient has the thrombosis of the prosthetic valve.
so that we need to raise the INR, as soon as possible.
therefore, she needs heparin.
The use of low-molecular-weight heparin for prosthetic valves remains controversial, but there is agreement that monitoring of factor Xa levels is needed if this agent is used in patients with a prosthetic valve. Low-molecular-weight heparin is not optimal in this patient because anticoagulation may need to be quickly reversed, depending on subsequent therapy.
so that unfractionated heparin is the answer.
Congrats for your correct anticipation !!!
