A giant left ventricular pseudo-pseudoaneurysm following myocardial infarction.

The ventricular pseudo-pseudoaneurysm is extremely scarce and potentially lethal because of acute hemopericardium and cardiac tamponade when a resultant complete tear occurs. Pseudo-pseudoaneurysms, which are formed by incomplete rupture of the myocardium, are usually small and limited to the thickness of the cardiac wall. We reported an uncommon case of a giant left ventricular pseudo-pseudoaneurysm, which was initially suspected by transthoracic echocardiography as a pseudoaneurysm.
