Bioprosthetic valve thrombosis (BPVT) is an important and potentially reversible cause
of valvular dysfunction. This complication can occur many years after surgery and
understanding of the precise mechanisms and risk factors is limited. Anticoagulation
therapy has been demonstrated to be effective in improving BPVT. However, the optimal
duration of therapy and the risk of recurrence are unknown. Herein, we describe two
cases—one of late BPVT and one of recurrence of BPVT after cessation of anticoagulation
therapy.
