An unusual case of postoperative pseudoaneurysm of the left ventricle: Doppler echocardiographic findings

Two years and 9 months after aneurysmectomy of a true left ventricular aneurysm, a 55 year old man presented with clinical features suggestive of acute pericarditis. The echocardiogram revealed a large echo-free space outside the heart. Doppler study showed phasic flow between the echo-free space and the left ventricular cavity through a distinct interruption of the left ventricular apical wall endocardial echoes. The diagnosis of pseudoaneurysm was made and was subsequently confirmed by angiographic and operative findings. After successful repair, a repeat Doppler echocardiographic examination showed a marked reduction in the echo-free space, absence of communication with the left ventricle and no flow signal in the space.
