Prosthetic Valve Thrombosis Presenting as an Acute Embolic Myocardial Infarction in a Pregnant Patient: Issues on Anticoagulation Regimens and Thrombolytic Therapy

Mechanical valves are inherently thrombogenic and require meticulous anticoagulation. Pregnancy produces a hypercoagulable state and achieving adequate anticoagulation is difficult. We present a pregnant patient who had a nonobstructive thrombus of mechanical mitral valve causing embolic acute myocardial infarction. Issues surrounding management of anticoagulation and use of thrombolytic therapy during pregnancy are discussed. Education regarding the critical nature of adequate anticoagulation in these patients is important.
