Stroke may herald fatal prosthetic valve thrombosis; this Level 5 case leaves open optimal screening and anticoagulation strategies.
Prosthetic valve thrombosis is a serious complication of valve replacement associated with a high mortality rate. Stroke may be the first symptom of prosthetic valve thrombosis. We present the case of a patient who visited the emergency department with symptoms of dysarthria and left hemiparesis. An examination revealed an ischemic stroke with hemorrhagic transformation, stemming from a thrombosis of their mitral valve prosthesis, which progressed to the patient's death. We emphasize the difficulty in the therapeutic and diagnostic management of these patients.
