Acute Myocardial Infarction Secondary to Coronary Embolism in a Patient with Mitral and Aortic Valve Prothesis

Prosthetic cardiac valve thrombosis is a serious and potentially lethal complication. Prosthetic valve thrombosis generally related to inadequate anticoagulation can result in systemic emboli. In recent years, increasing rate of prosthetic valvular surgery has been another significant source for coronary emboli. Myocardial infarction secondary to coronary embolization is an infrequent but life-threatening complication of cardiac valve replacement. In this paper, it was presented a case of coronary embolus resulting in acute myocardial infarction in a patient with prosthetic mitral and aortic valves taking inadequate anticoagulation therapy.
