[Echocardiographic diagnosis of a rare mechanical complication of biventricular infarction. Rupture of the free wall of the right ventricle].

The authors report a case of rupture of the free wall of the right ventricle, diagnosed by two dimensional echocardiography. This examination revealed an intrapericardial clot associated with a fissure of the diaphragmatic wall of the right ventricle. This case emphasises the value of two dimensional echocardiography in the acute phase of myocardial infarction for the diagnosis of complications which require urgent surgical treatment.
