[2 cases of acute myocardial infarct complicated by fatal pulmonary embolism].

Two cases of pulmonary embolism with lethal course in the setting of acute myocardial infarction are presented. Both cases are clinically characterized by a late pulmonary embolism occurrence (2nd and 3rd week, respectively), and the presence of a large infarct, heart failure during acute myocardial infarction evolution and the interruption of anticoagulant therapy due to a complication. From the anatomic point of view, both cases had large hearts and very large biventricular infarctions. On the other hand, deep venous plexus constituted the pulmonary embolism origin in one case, and right ventricular thrombosis in the other.
