Ventricular aneurysm: false or True? An important distinction.

A case of ventricular false aneurysm withe the typical clinical, radiological, electrocardiographic, and angiographic features of this entity is presented. The distinction between false ventricular aneurysm and true aneurysm is discussed. This distinction is important because of the propensity of false aneurysms to rupture. An early diastolic murmur was present prior to, but not after, resection of the aneurysmal sac. A theory as to the origin of this murmur is offered.
