Unknown extra cardiac echo-free space: diagnosis of a left ventricular pseudoaneurysm by color flow echocardiography.

At times, visualization of a ventricular pseudoaneurysm by two-dimensional echocardiography can be difficult. This case report describes the unique diagnostic potential of color flow echocardiography in the diagnosis of an unknown extra cardiac echo-free space, a left ventricular pseudoaneurysm. Using color Doppler echocardiography flow can be seen communicating between the left ventricle and the pseudoaneurysm.
