A localized outpouching of ventricular cavity that is generally associated with dyskinesia and paradoxical expansion during systole.

Aneurysm is considered a severe form of dilatation. Ventricular aneurysms may have rim of calcium in the affected regions of the ventricular wall (which can become fibrotic). Thromboembolism is a potential complication. Ventricular aneurysms can be diagnosed by ventriculography.
