Prosthetic valve thrombosis is a rare and dreaded complication of patients with mechanical valves, particularly those in the mitral position. A 45-year-old female with status post prosthetic mitral valve replacement was admitted to the hospital with acute pulmonary edema. Echocardiography showed mitral valve thrombosis which was treated with tissue plasminogen activator (t-PA). During t-PA infusion she developed acute inferoposterior myocardial infarction. Coronary angiography showed normal coronary arteries. Presented case had acute inferoposterior myocardial infarction secondary to coronary emboli after the successful thrombolytic treatment of prosthetic mitral valve thrombosis.
