Abstract
Prosthetic valve thrombosis, a serious complication of prosthetic valve replacement, can be lethal without proper treatment. Right-sided valve thrombosis is rare but several therapeutic modalities can be considered: anticoagulation therapy, fibrinolysis, or surgery. Here, we report a case of significant tricuspid valve thrombosis which failed fibrinolytic therapy requiring repeat sternotomy with repeat tricuspid valve replacement with a porcine bioprosthesis.
