[Echocardiographic diagnosis of rupture of the interventricular septum and release into the wall of the left ventricle (with formation of pseudoaneurysm) in inferior myocardial infarction].

A case of inferior myocardial infarction in a 77 years old woman suffering from angina pectoris for 8 years, is reported. The clinical course was complicated by mild heart failure secondary to interventricular septum repture, diagnosed by Doppler-echocardiography. The patient was discharged in III-IV NYHA class with medical therapy. Then, unstable hemodynamic conditions and episodes of angina pectoris occurred again. Five months after acute myocardial infarction, echocardiography confirmed the interventricular septum defect. An echocardiographic control, performed 17 months after the acute episode, documented, besides previous data, the presence of a pseudoaneurysm of the inferior wall with a large cavity in communication with the left ventricle.
