[Unusual development of ventricular aneurysms. Echocardiographic diagnosis].

Two cases of posterior left ventricular aneurysms compressing the left atrium diagnosed by 2D echocardiography are reported. The diagnosis was made on visualisation of an abnormal intra-left atrial cavity, contiguous with the mitral ring, exhibiting systolic expansion, which could not be opacified by peripheral venous injection of echo-contrast.
