Chronic false left ventricular aneurysms have a propensity to rupture and cause sudden death, in contrast to chronic true aneurysms which tend not to rupture.
Chronic false LV aneurysms may rupture even when small; case reports leave open need for prospective data on surveillance.
Two cases are described of sudden death resulting from rupture of small chronic false aneurysm of the left ventricle with secondary hemopericardium. The cases support the point that rupture of chronic false left ventricular aneurysm tends to occur. This appears to be contrary to the potential for chronic true aneurysms of the left ventricle which tend not to rupture. Rupture of true left ventriuclar aneurysm in its deveoping stahe may, however, occur.
