I had a patient who had a bioprosthetic aortic valve replacement a few months prior, and I was giving handoff report to my coworker who is an ex-CVICU nurse and he asked what anticoagulation the patient was on. I said I didn't think he needed anticoagulation but the ex-CVICU nurse said that patients that are s/p bioprosthetic valve do require anticoagulation "for a while."
I was hoping someone could elaborate on that for me. Is this all bioprosthetic valves? Why do they need anticoagulation? How long do they need to be anticoagulated?

This is from an article on the American College of Cardiology website.
Thrombotic and embolic complications and anticoagulation-related bleeding are by far the most prevalent contributors to morbidity and mortality after surgery for VHD [valvular heart disease].8,9 The risk of thromboembolic complications is greatest during the first three months after surgery for both mechanical and bioprosthetic devices, with persistent life-long risk for patients with mechanical valves. - See more at: Bad Request
The surgeons I work with do typically prescribe AC therapy for 3 months post-bioprosthetic valve implantation.
Not sure why the link says Bad Request, it works fine for me.
