ABSTRACT
Examinations were performed in 153 consecutive patients with myocardial infarction (MS), which were divided into two groups. Group I (21 persons) consisted of patients with echocardiographically diagnosed left ventricular mural thrombus, and in group II were patients without evidence of thrombi. Significantly more patients with anterior myocardial infarction were in the the group I, whereas those with inferior MI in the group II. Increased left ventricular wall contractility index and considerably percentage of dyskinesis, mostly of the apex region were stated in the group I. 15 patients (71%) of the group I were treated with heparin, but only 4 of them within 4 hours from the beginning of angina pain. In 4 patients of the group I (19%) thromboembolic complications occurred: in 1 patient during proper anticoagulant therapy and in 3 others without treatment with heparin. Thus mural thrombi were observed in majority in patients with anterior myocardial infarction and were localized in a diskinetic region. Echocardiograms of patients with mural thrombi testified to greater than in others left ventricular function impairment. Heparin administration during first hours of myocardial infarction seemed to lower the incidence of mural thrombi and probably thrombembolic complications.

Authors presented intravitally diagnosed and well echocardiographically supplied documentary evidence for a huge thrombus positioned in the left atrioventricular ostium in a 52 years old woman within two months of Björk-Shiley mitral valve replacement because of a mitral valve disease.
