Introduction:
The mechanism of Bioprosthetic valve (BPV) dysfunction is predominantly due to structural deterioration. Bioprosthetic valve thrombosis (BPVT) has traditionally been considered a rare event. However, recent data suggest that BPVT is not uncommon and in fact an increasingly recognized entity. The true incidence of BPVT may be underestimated as most cases remain under diagnosed. The diagnosis can be challenging due to low general awareness of the condition. A high degree of clinical suspicion and formal echocardiographic criteria can accurately diagnose BPVT. Early diagnosis remains crucial as it can be successfully treated with anticoagulation.
