[False aneurysm of the left ventricle during the acute phase of myocardial infarction: diagnosis by transesophageal echocardiography].
The authors report a case of myocardial infarction complicated by a false aneurysm of the posterior wall of the left ventricle, the diagnosis of which was confirmed, for the first time, by transesophageal echocardiography (TEE) which provided better definition of the anatomical features of the lesion: visualisation of the particularly wide neck (5 cm) and the site of rupture of the myocardium; demonstration of the presence in the false aneurysm with a thin pericardial wall of a large thrombus of different acoustic density, itself overlain by swirling whorls. Colour Doppler combined with TEE clearly showed the acceleration of flow at the neck and its slowing in the newly formed cavity. Once the diagnosis was made, the patient rapidly underwent surgery with a successful outcome. The quality of the images obtained without risk by TEE suggests the important role which this investigation could play in the future in the diagnosis of certain mechanical complications of myocardial infarction.
