Abstract

We herein describe a case and provide images of a bioprosthetic mitral valve thrombosis and a huge left atrial appendage thrombus occurring during atrial fibrillation 12 years after initial heart surgery. The patient was treated conservatively with oral anti-coagulation because he was a high surgical risk with complete resolution of the thrombosis after 2 months of therapy. This case suggests that in a high surgical risk patient, effective oral anticoagulation might be a good alternative to surgery.
