Acute ST-elevation inferior myocardial infarction in a patient with a non-obstructive mechanical mitral valve thrombosis

Abstract

The risk of systemic embolisation in patients with prosthetic heart valves who are receiving anticoagulation therapy is 0.5 to 1.7% per patient year and most cases present with cerebrovascular events. Here we report the case of a 42-year-old woman who was uneventfully treated with a low dose, prolonged infusion of tissue plasminogen activator because of non-obstructive prosthetic mitral valve thrombosis. It presented as coronary embolism and resulted in acute ST-elevation inferior myocardial infarction.
