Abstract
Mechanical heart valve thrombosis is not so rare in pregnant women because of the difficulties in managing anticoagulant treatment and the hypercoagulability state associated with pregnancy. Among the embolic complications of valve prosthetic thrombosis, the coronary embolism is rare, it requires an urgent pharmaco-invasive approach which must be adapted to this particular associated condition. We report the observation and the difficulties of managing antithrombotic therapy in a pregnant patient hospitalized for non-obstructive prosthetic valve thrombosis complicated by coronary embolism and resulting in ST elevation myocardial infarction.
